When NVIDIA Corp. (Nasdaq: NVDA) split 10-for-1 in June 2024, more retail investors had the opportunity to leverage this stock to sell options. Many already owned NVDA, but now owned 10x the number of shares at 1/10 the price. Writing covered calls against this security created an opportunity for a cash flow on a superior-performing stock (at that point in time). This article will analyze one way to write covered calls using NVDA and implied volatility to both generate income and create a high probability of avoiding exercise of the options and subsequent sale of the shares. This approach to covered call writing is known as portfolio overwriting.
What is portfolio overwriting?
This is a covered call writing-like strategy where deep out-of-the-money (OTM) calls are written to both generate cash-flow and create a low probability of exercise.
What is implied volatility (IV)?
IV is a forecast of the underlying stock’s volatility as implied by the option’s price in the marketplace. Implied volatility stats are based on annualized price movement and 1 standard deviation (expected to fall into the price movement range approximately 68% of the time). To make IV specific to the contract we are considering, we must use a conversion formula to calculate the expected trading range. The BCI Expected Price Movement Calculator will accomplish this for us, using an at-the-money (ATM) IV for the contract in consideration. The conversion formula is inherent in the spreadsheet. Of the remaining 32%, 16% is expected to fall under and 16% above the range. Our concern when portfolio overwriting is the high end. If share price moves above the deep OTM call strike, our shares are subject to exercise (sale).
Determining the ATM IV for NVDA ($124.42) for the 7/26/2024 expiration

The near-the-money $124.00 shows an IV of 51%.
Calculating the expected trading range with an emphasis on the high end to avoid exercise

We will check an option-chain for the deep OTM $142.00 strike which will give us an (approximately) 84% probability of not falling outside the projected range.
NVDA deep OTM option-chain

The $142.00 deep OTM strike shows a bid price of $2.56. Let’s calculate using the BCI Trade Management Calculator (TMC).
NVDA initial calculations

- Yellow cell: The BE price is $121.86
- Brown cells: The initial 30-day return is 2.06%, 25.03% annualized
- Purple cell: There is an upside potential opportunity of 14.13%
Discussion
When seeking to generate cash-flow while, at the same time, looking to avoid exercise, using IV and the BCI Expected Price Movement Calculator can create 84% probability-of -success trades. Even if share price does move beyond the deep OTM call strike selected, we can always buy back or roll that option prior to expiration.

Covered call writing is a cash-generating strategy that lowers our cost basis thereby improving our opportunities for successful investments. It involves a long stock position (we buy the stock) and a short option position (we sell the call option). The PMCC strategy replaces the long stock positions with long call positions, typically deep in-the-money long-term expiration options known as LEAPS. Because long options cost less than stocks, we are investing less money and the return on our capital increases. As with all strategies, there are pros and cons that must be mastered to determine if this is a proper strategy for our personal risk-tolerance and return goals. This program will highlight in great detail:
- PMCC definition
- Pros and Cons
- Risk/reward profile
- Best stocks and ETFs to consider
- How to construct a PMCC trade
- Hypothetical example
- Multiple real-life examples

Alan,
At the start of your recent webinar, you said that covered call writing is less risky than buying stock. Can you explain the reasoning behind this?
Thanks a lot for your time.
Keith
Keith,
When we write covered calls or cash-secured puts, we are lowering our cost-basis or breakeven price points.
For example, if we buy a stock for $50.00 and sell the $55.00 call for $2.00, our breakeven price is $48.00. Without the covered call, it is $50.00.
Now, we are capping the upside, and that is why we must be proficient at strike selection based on overall market assessment, personal risk-tolerance and chart technical parameters.
Lowering our cost basis by selling stock options puts us in a position to potentially beat the market on a consistent basis and many years substantially.
Add to this our exit strategy arsenal and we are in a position to become elite, successful investors.

Alan,
I sell mainly weekly options.
I am a bit concerned about the Fed announcement on Wednesday if there is no rate cut.
Should i just skip this week?
Thanks for any advice.
Sid
Sid,
I can’t give specific financial advice in this venue, but I’m happy to share how I manage Fed announcements.
Since there is a minimum of 8 Fed announcements per calendar year, avoiding them would have a major negative impact on our annualized returns. I don’t avoid them.
However, if there is a specific report that I feel may impact the market negatively in a significant way, I will opt for defensive approaches to my option trades.
For example, I may sell a deep OTM cash-secured put to enter a covered call trade (PCP or “wheel” strategy).
We can also sell ITM covered calls and take advantage of the intrinsic-value components to lower the breakeven price points.
For those who are more concerned over these Fed announcements than I am, taking the week off should be a consideration.
Alan
Hello Alan.
Reviewing the article on NVDA overwriting I did some calculations and it appears to me that if I just use deltas between .16 and .22 I get approximately the same results.
Although I like the price movement calculator, I wonder what the advantage over just using delta?
Thanks
Bob
Bob,
Both Delta and IV are reliable tools we can use to determine the approximate probability of expiring in-the-money (with intrinsic-value) and selecting an appropriate strike price. I will frequently use one to confirm the other.
A few years ago, I did a comparative study of > 100 stocks to see if there was a difference between strikes determined by 16% Deltas and IV conversions. The strikes were similar, but not always precisely the same.
Using the BCI Expected Price Movement Calculator, we also get a low end of the range which we can use when writing deep out-of-the-money cash-secured puts or deep in-the-money covered calls. This can actually also be accomplished by using high Deltas (84%, as an example).
Let’s keep both in our management toolbox.

Today’s market:
Today, the Fed cut interest rates 25 basis points as expected. However, it signaled only 2 rate cuts in 2025, a disappointment to the market. It appears that Wednesday’s market decline was an overreaction to the Fed statement and press conference and, hopefully, we’ll see a recovery leading into the end of the year. As uncomfortable as a day like today is, there is no reason to panic when analyzing the overall market health.
