Advance Posting
Posted by Mark on March 15, 2024 at 08:59 | Last modified: March 14, 2024 10:11I feel compelled to make a brief entry about my tendency toward posting blog entries in advance.
At the end of the first paragraph here, I write:
> The investing world hasn’t heard from me since.
Followers of this blog had actually been reading consistent posts through Groundhog Day of this year. My regulars probably also know that over the years, I typically post twice per week: Mon / Thurs or Tues / Fri (with an occasional tweak due to market holidays). In doing five stock studies per week for most of 2023, I had more than enough posts to meet my quota of two. I therefore kept posting farther in advance even though many weeks I’d publish an additional post on what should have been a day off. My entry dated 2-2-2024 was actually written 10-26-2023.
When I post is of no real consequence as long as I get the posts done. I appreciate my loyal readers coming along for the ride but ultimately, the blog is to hold me accountable for my projects and work. The last post illustrates what critical importance it plays to that end; without the blog, I might as well be—dare I say—retired??
Were this for my readers, then it would be fair for me to charge a small fee (somewhat reminiscent of the group proposed here except as a blog subscriber you would not be required to contribute content). I have used methodology discussed in this blog to make money for myself and you could surely do the same.
My blog is not monetized, however, and never has been. Not only do I make zero money from its maintenance, I pay a pretty penny between registering the domain name, subscribing to web hosting services, etc.
This will be a shorter post as I have no more to say on the matter. I’m also giving myself a slight break since I just got off the schneid. Despite being shorter, it fulfills my quota of two per week: a huge accomplishment not realized since last October! I remain 10 posts behind, but only readers who keep up with the blog live will notice because entries made in the near future will be backdated to fill in the holes (i.e. “posting in arrears” as opposed to “advance posting”).
To coin a phrase, it’s much ado about nothing.

Posted by Mark on March 12, 2024 at 10:04 | Last modified: March 13, 2024 12:11I did an amazing thing last year with First Cut stock studies: 209 of them! Two hundred nine. The time required for data collection, completing a stock study guide and First Cut report, and blog posting averaged 3-4 hours thereby making for a substantial annual commitment. I began my journey with 55 studies between Sep – Nov 2022 before taking a 65-day break and resuming on Jan 12, 2023. I then did one study per trading day through Oct 26 before a technical glitch blocked access to the M* website through my local library. Expecting this would take days to fix, I waited. Days turned into weeks, however, and I fell off the wagon. The investing world hasn’t heard from me since.
During the interlude, my brain has been in a state of—hibernation? Unwelcomed sabbatical? I really don’t know! I’ve taken breaks before (such as the 2+ months mentioned above), but not this long. Everything else in my life has been proceeding as usual including my trading. Trading pays the bills and takes less than 30 minutes per day; thankfully no interruption has been seen there. In my mind, however, the “optional activities” discussed in these first three paragraphs are what make the difference between working and retirement. Since those optional activities have now been absent for a while, I’ve started thinking of myself as “semi-retired.”
I don’t want to be done yet, though. I feel I have at least one more act left.
First things first: write this post. Since I haven’t blogged in what seems like ages, it took a herculean effort to do basics like login to WordPress, get into my blog folder, search the title index for links, remember what to do with tags, etc. These tasks are automatic when I’m doing them multiple times per week but after four months away, a chisel is needed for newfound rust.
I can now be the last, probably, to say Happy New Year to everyone! Greetings after a long hiatus.
My plan going forward, first and foremost, is to catch up on the blog. This will involve many of the things I wish to revisit: restarting the stock study engine, backtesting option strategies, catching up on financial journals, and studying other investment ideas from my reading or personal trading. Perhaps I’ll also process some of what I have learned from the BetterInvesting volunteer program.
Today’s goal was just to get this post done—whether adequately proofread or not—thereby getting me off the schneid. Tomorrow I’ll need to follow-through but for the time being, mission accomplished!

Posted by Mark on March 1, 2024 at 11:41 | Last modified: March 26, 2024 11:28The last table in Part 7 shows pricing data for synthetic long stock (SLS) positions in SPX: a combination of different expirations and strike prices. This brings me to a shocking revelation.
Walking the chain reveals loss from holding the SLS position. This means looking forward in time to get an idea what pricing will be like if “all else remains equal.” 91 days from now, the Sep position—now 182 DTE with a cost of $76.90—will be 91 DTE. Looking at the 91 DTE option chain (hence “walking the chain”) today (Jun expiration) shows the Jun 5275 SLS costs $21.10. 63 days after that, the Sep position would be like today’s Apr position with 28 DTE: established for an $18.40 credit. What I originally purchase for $76.90 will cost me an additional $18.40 to close in 154 days. That represents a loss of $76.90 + $18.40 = $95.30 or $9,530 per contract.
Say what?
The risk graph provides confirmation:
The purple line on 3/21/24 shows a current PnL of -$219.59. The cyan line on 9/21/24 shows a PnL in 182 days of -$11,609.10. This is a loss of $11,389.53. The SLS saves $523,599 (cost of 100 shares) – $7,690 (cost of SLS) = $515,909 for a [all-else-remains-equal] cost of (11,389.53 / 515,900) * (182 / 365) * 100% = 4.43%/year of the capital saved.
Let’s review.
I have been exploring the idea of trading SLS + T-bills as a way to get equivalent long stock exposure and bond interest.
I just discovered that trading the SLS incurs a cost that offsets most interest paid by T-bills.
What we have is another instance [so often heard when studying investing/trading/finance] of “no free lunch.” Also coming to mind is “can’t eat your cake and have it too.”
I had been starting to think trading SLS and investing in T-bills might provide an edge over buying the long stock outright. Rather than a potential edge to be had, I now see it more like a detriment suffered if T-bills are not purchased while holding the SLS. As an option trader with lots of free cash, T-bills must be purchased to avoid missing out on what is basically free money. As a more traditional equity investor, while T-bills still appear to be the better deal (by roughly 0.47%), I’m not convinced going the SLS route is worth doing given the remaining considerations when comparing the two.
I’d be lying if I denied any presence of sour grapes right now. The Options Playbook says:
> For… [SLS], time decay is somewhat neutral. It will erode the value of the option
> you bought (bad) but it will also erode the value of the option you sold (good).
Nothing could be farther from the truth in today’s environment.
I will continue next time exploring why this might be.

Posted by Mark on February 27, 2024 at 10:26 | Last modified: March 25, 2024 15:04Before continuing to compare stock investing (S&P 500 ETFs and mutual funds, in particular) with synthetic long stock / T-bills, I have some other loose ends to tie up.
Let’s detail the first footnote from Part 4:
> The call is more expensive than the put because it includes over
> $2.00 intrinsic value. This is touched upon in the third paragraph
> here,but I would refer you to an introductory book/article on options
> for a more complete explanation. For at-the-money equity
> options, puts [premiums] are generally more expensive than calls.
The Options Playbook echoes this:
> If the stock price is above strike A, the long call will usually cost
> more than the short put. So the strategy will be established for a
> net debit. If the stock price is below strike A, you will usually
> receive more for the short put than you pay for the long call so
> the strategy will be established for a net credit. Remember: the
> net debit paid or net credit received to establish this strategy will
> be affected by where the stock price is relative to the strike price.
As I write in this sixth paragraph:
> Lots of ideas from financial professionals and investment gurus
> sound good, but I believe the only way to understand what has
> truly worked is to analyze the data.
Let’s turn to some data in the form of option chains from three different expirations:
>
>
>
Extracting data from the circled columns, date, and highlighted strikes:
“SLS [Synthetic Long Stock] Natural Price” is the call [ask] premium minus put [bid] premium.
“Total bid/ask” is the sum of the ask premium minus bid premium for both call and put.
Although intrinsic value (strike price minus underlying price for puts and underlying price minus strike price for calls) is nonnegative, I have used a positive (purchase) and negative (sale) sign for calls and puts, respectively, in the “Intrinsic Val” column. This facilitates evaluation of the hypothesis that intrinsic value in calls (puts) makes SLS price higher (lower).
SLS price does indeed go down as intrinsic value shifts toward the puts.
In only one instance out of 14 is SLS price negative, however. I expected SLS of equal and opposite moneyness to have equal and opposite price (as Options Playbook implies above). A closer look at the option chains reveals calls in these near-the-money strikes to be more expensive than puts. This runs contrary to traditional wisdom about vertical skew ever since Black Monday (1987) and demands further research.
But wait: there’s more!
Next time I will continue with the most shocking revelation of all.

Posted by Mark on February 22, 2024 at 13:24 | Last modified: March 24, 2024 08:57Today, I continue addressing the first consideration when comparing stock investing (S&P 500 ETFs and mutual funds, in particular) with synthetic long stock / T-bills.
As mentioned in the second-to-last paragraph of Part 5, synthetic long stock requires advanced trading permissions from the broker [score one point for stock investing]. I think this is mainly due to a need for close monitoring as expiration approaches and knowledge required about proper management depending on whether the underlying has gone up or down.
If the underlying (ETF) has increased through expiration,* the long call must be sold [thereby incurring slippage, commission, and exchange fees—score another point for stock investing] because automatic exercise will occur if in-the-money (ITM) by at least $0.01. This cannot be allowed to happen because avoiding stock purchase is precisely why the synthetic is being traded in the first place. The short put can probably be left to expire with close monitoring for sudden downside movement if the ETF is trading anywhere near the stock price** in order to prevent what I will describe next.
If the underlying has decreased through expiration,* the short put must be bought (to close) [again incurring slippage, commission, and exchange fees]. The short put may be assigned early if it goes deep ITM or assigned at/near expiration if it is even slightly ITM. Extrinsic value is something to be monitored; if this shrinks to a penny or two,*** then immediate closing (rolling) is prudent. Any extrinsic value in the long call could be salvaged by a sale. In fact, for the synthetic long stock to perfectly mimic gain/loss of the underlying shares, both options should be closed together and concomitantly replaced with a later-dated position.****
I have at least two ideas to significantly limit assignment risk. First, avoid expiration week altogether by rolling synthetic long stock no later than 7 DTE. Especially if positions are established far from expiration, the difference between rolling at 7 DTE vs. expiration week proper is trifling. Second, trade the synthetic with SPX options rather than SPY. Any assignment of SPX options results in a cash credit/debit for the difference between strike price and underlying [SPX index] price rather than an obligation to buy the full 100 shares of SPY [multiplied by number of contracts].
I will continue next time with a brief discussion of option liquidity for S&P 500 ETFs.
>
>
* — Assuming an at-the-money synthetic stock position at inception, which need not be the case.
** — This applies more to PM-settled options that can be monitored right up to expiration. Closing
AM-settled by 4:15 PM ET (check option specifications for exact trading hours) is prudent
when trading within a couple (few?) standard deviations of the strike price to limit chances
of a big overnight move resulting in assignment.
*** — $0.05 – $0.10 for SPX options
**** — “Concomitantly” makes this a theoretical impossibility but opening a new synthetic long
stock position ASAP after closing the existing is sufficient.
Investing in T-bills (Part 5)
Posted by Mark on February 20, 2024 at 11:37 | Last modified: March 20, 2024 21:37Having now completed the comparison between long calls and short puts, we’re now ready to consider both at once.
A long call and short put opened at the same strike price produce a risk graph that may look familiar:
This is known as synthetic long stock. One contract of each option will be virtually identical to 100 shares of the underlying stock (SPY ETF in this example) with regard to profit/loss.
Here are the vitals:
- The cost to open this position is $14.14 – $8.31 = $5.83/contract (or $583 compared to $51,220 to buy the stock).
- The purple (cyan) curve shows profit and loss today (in 59 days at May expiration) based on a range of prices for SPY.
- Like stock, this has unlimited profit potential and maximum loss to be realized if SPY goes to zero at expiration.
>
For purposes of T-bill investment, the cost savings is paramount: $51,220 – $583 = $50,637 saved via synthetic stock can buy T-bills for a guaranteed [by the full faith and credit of the United States government] return of [currently] over 5.0% per year.
This blog mini-series has led to exploration of synthetic long stock as a higher-performance alternative to stock shares. Most people who invest in mutual funds or ETFs are committing the full $51,220 mentioned above without any T-bill exposure. What about trading options for a fraction of the cost and getting 5%/year on the difference?
I can’t find any supporting statistics, but I would venture to say investment in S&P 500 index mutual funds and/or S&P 500 ETFs are the most popular equity investments in existence (coming in a close second may be total stock market funds/ETFs). S&P 500 vehicles are offered in every retirement plan I have ever seen, heard of, or read about. Most articles I study in financial journals use these index mutual funds or ETFs (e.g. SPY, IVV, VOO) as a proxy for equity investment performance. They also have among the lowest expense ratios and narrowest bid/ask spreads of any issues traded on Earth.
The first of several considerations to be made when comparing long stock to synthetic long stock / T-bills is option trading permissions. Option trading levels range from beginner to advanced and different brokers have different categories. TD Ameritrade has three “tiers” while Interactive Brokers has four levels of “option trading permissions.” Most novice traders and IRA accounts receive basic authorization that enables use of covered calls and long call or put contracts. This requires some basic options knowledge and a cash or IRA account with enough funding. More advanced authorization usually requires a margin account. Since the broker risks losing money by lending funds, these levels require some options trading experience and sufficient funds or assets in the account to cover any losses.
The short put places synthetic long stock into a more advanced option trading category. Not being applicable to everyone is a disadvantage because it would therefore require added cost for an authorized trader (investment advisor) to manage.
I will continue next time.

Posted by Mark on February 16, 2024 at 10:18 | Last modified: March 19, 2024 12:14I discussed put selling (also known as “short puts” or “naked puts”) last time as a way to participate in underlying stock appreciation in combination with T-bill investing. Before moving forward, I want to tie up some loose ends and present a different way of visualizing previous concepts.
Risk graphs are a way of visualizing potential risk and reward of option positions. I compared and contrasted such details for long calls and short puts in Part 3.
Here is the risk graph for a long call:
- This call is purchased for $14.14/share (the default multiplier for equity options is 100 shares per contract so buying one of these actually costs $14.14 * 100 = $1,414) with SPY [stock, or more precisely ETF] at $512.20/share (early morning on 3/19/24; see second-to-last paragraph here if the dates really confuse you).
- The purple (cyan) curve shows profit and loss today (in 59 days at May expiration) based on a range of prices for SPY.
- Note how the purple curve will sink down to the cyan over time. This represents the premium paid for the call and how some of that premium may be recovered by selling to close prior to expiration (total premium is reflected in the value of the cyan curve to the left: -$1,414).
- Note the unlimited profit potential as the curves have positive slope to the right.
>
Here is the risk graph for a short put:
- This put is sold for $8.31/share ($831/contract) with SPY at $512.40/share (early morning on 3/19/24).*
- The purple (cyan) curve shows profit and loss today (in 59 days at May expiration) based on a range of prices for SPY.
- Note how the purple curve rises to the cyan over time. This represents the premium received for the put and how some of that premium must be surrendered when buying to close prior to expiration (total premium is reflected in the value of the cyan curve to the right: +$831).
- Note the unlimited [technically limited by SPY reaching zero because stock prices cannot go negative] loss potential as the curves have negative slope to the left.**
>
Buying calls depletes whereas selling puts raises cash that may be used to invest in T-bills. If the calls become profitable, however, then selling them will increase cash balance whereas closing a short put (or letting it expire) after the underlying stock has decreased can lower cash balance (more on this later).
I will continue next time.
* — The call is more expensive than the put because it includes over $2.00 intrinsic value. This is touched upon in
the third paragraph here, but I would refer you to an introductory book/article on options for a more complete
explanation. For at-the-money equity options, puts [premium] are generally more expensive than calls.
** — One naked put carries less risk than 100 shares of stock because its maximal loss is offset by the premium
received for selling it. This is discussed in further depth here.
Investing in T-bills (Part 3)
Posted by Mark on February 13, 2024 at 11:09 | Last modified: March 18, 2024 16:33In Part 2, I wrote about investing in T-bills while buying calls (also known as “long calls”) in the same account. Today, I will review that discussion and introduce put selling (also known as “short puts” or “naked puts”).
Long calls generally increase in value with the underlying stock once the increase is enough to offset the initial premium previously described as “rent.” In that example from the sixth paragraph here), I pay $13.73/share premium to buy the calls. After 62 days, my position will be profitable if SPY stock [an ETF] has gone up more than $13.73/share and no limit exists to how profitable these may be (net the initial $13.73 premium). If SPY increases less than $13.73/share, my position loses money. If SPY does not increase at all after 62 days, then my whole investment is lost (albeit only 2.7% of the cost to buy 200 shares outright).
I can only buy as many calls as the free cash in my account will allow (self-imposed guideline: I never want to borrow brokerage funds and owe upwards of 13% interest). Buying calls decreases free cash that may be used for T-bill investing.
Aside from buying calls, another way to participate in the movement of underlying stock is to sell puts. Long (bought) puts generally gain value as the underlying stock falls and sold (short) puts generally gain value as the underlying stock rallies. Selling puts allows me to collect premium rather than paying it; this provides a margin of safety if the underlying stock falls.
As an example, rather than buying the calls previously discussed, suppose I collect the $13.73/share premium by selling the corresponding puts.
The story is now different in several ways:
- First, the premium received for put sales (vs. premium due for call purchase) increases the cash balance in my account that I can use to buy T-bills.
- Second, if SPY increases over 62 days, then I keep the $13.73/share profit (vs. having to overcome any premium paid for profitability).
- Third, $13.73/share is my maximum potential profit (vs. unlimited profit potential net premium paid for long calls).
- Fourth, if SPY decreases up to $13.73/share, then I will have to surrender up to the entire premium received after 62 days. A net loss results if SPY decreases more than $13.73 (vs. long calls that incur maximum loss if SPY goes down at all). Potential loss on the short put is nearly unlimited except for the $13.73/share premium initially received.

I will continue next time.

Posted by Mark on February 8, 2024 at 06:56 | Last modified: March 16, 2024 12:02Last time I presented Investopedia information on the basics of T-bills: what they are, how they work, etc. Today I’m going to start discussing why to consider investing in them.
I invest in T-bills to get a better interest rate on cash than I otherwise would. I tend to have free cash in my brokerage account. The brokerage currently pays 0.35% interest on that cash. According to the Bankrate website, the national average yield for savings accounts is 0.57%. T-bills are currently paying over 5.0% interest.
Borrowing brokerage money to invest in T-bills would be a losing proposition. Suppose I open a margin account with $100,000 cash. I can buy stock with $100,000 and T-bills with $50,000. I will make 5% interest on the T-bills, but since that $50,000 is borrowed from the brokerage I will have to pay upwards of 13% interest. This is a guaranteed loss of at least (13% – 5%) = 8%. Bad idea… really bad idea.
For those investing in stocks, T-bills may not add much benefit. A stock investor opens a brokerage account to buy stocks. Most of the cash will therefore be deployed to that end. $95,000 may be used to purchase stock in a $100,000 account. This leaves only $5,000 to buy T-bills. It may still be worthwhile to do so, but T-bill investing does carry a minimal time commitment (to be discussed later).
Because options are leveraged instruments, cash outlays are different. Options allow me to control stock for a fraction of the cost. This means more leftover cash that I can conceivably use to purchase T-bills.
Imagine buying calls in the hypothetical account discussed above. With SPY at $509.83/share, I can buy 200 shares of SPY for $101,966. Alternatively, two 510 calls would cost me $2,746. This allows me to effectively rent 200 shares of SPY for 62 days. My position is then worth the difference of SPY and $510 [multiplied by two (options)]. If SPY is less than $510 then my position expires (i.e. “goes out,” “ends up”) worthless. If SPY is at $524, then my position is ~$2,800 (slight gain). If SPY is at $530, then my position is ~$4,000 [a much larger (percentage) gain].
With calls, I take on the risk of losing the full $2,746, but this is only 2.7% of the cost to buy shares. The leftover cash can be used to purchase T-bills. Interest received would be 0.05 * (100,000 – 2,746) * (62 / 365) ~ $849. With shares, because I borrowed $1,966 to establish the full position, I would actually owe 0.13 * 1,966 * (62 / 365 ) ~ $43 . The difference is $892 in about two months.
Interest aside, at the end of those two months the SPY position could also be down $2,746 were SPY to fall $13.73 (to $496.10/share). While this is an equivalent loss to the option position, I retain ownership of the shares and can subsequently recoup the loss if SPY moves higher. Expiring worthless means the option position can never rebound.
I will continue next time.

Posted by Mark on February 5, 2024 at 14:37 | Last modified: March 15, 2024 15:36I find an advantage to investing in Treasury Bills, but I am still trying to wrap my brain around how big a benefit this is, to what extent it may be utilized, and/or how much of it is real or just perceived.
Here are some basics courtesy of Investopedia:
> A Treasury bill [T-bill]… is a short-term U.S. government debt obligation
> backed by the Treasury Department with a maturity of one year or less.
> T-bills are usually sold in denominations of $1,000… These securities are

> a T-bill, the U.S. government effectively writes an IOU to the investor.
> Thus, T-bills are considered a safe and conservative investment since the
> U.S. government backs them.
>
> T-bills are generally held until the maturity date. However, some holders
> may wish to cash out before maturity and realize the short-term interest
> gains by reselling the investment in the secondary market.
>
> T-bills can have maturities of just a few days, but the maturities listed by
> the Treasury are are four, eight, 13, 17, 26, and 52 weeks.
>
> T-bills are issued at a discount from the par value (also known as the face
> value) of the bill, meaning the purchase price is less than the face value of
> the bill. So, for example, a $1,000 bill might cost the investor $950.
>
> When the bill matures, the investor is paid the face value—par value—of
> the bill they bought. If the face value amount exceeds the purchase price,
> the difference is the interest earned for the investor.
>
> T-bills do not pay regular interest payments as with a coupon bond, but a
> T-bill does include interest, reflected in the amount it pays when it matures.
>
> The interest income from T-bills is exempt from state and local income
> taxes. However, the interest income is subject to federal income tax.
>

I will get more into the details of investing with T-bills next time.
