One of the common mistakes made by covered call writers and put-sellers is to make investment decisions based primarily on the highest premium returns. Certainly, we all want to generate the highest levels of success but only when factoring in the risk we will be incurring. This article will look at high premium returns from the perspective of the underlying security as well as from the perspective of the “moneyness” of an out-of-the-money strike.
Time value profit and implied volatility of the underlying security
Our time value percentage profit is directly related to the implied volatility of the underlying security. This means that the higher the percentage return, the greater the downside risk. Generally, implied volatility (IV) statistics are based on a 1-year time frame and 1 standard deviation (accurate two-thirds of the time). If a stock shows an implied volatility of 25% and is trading at $60.00, the expected price range over the next year would be between $45.00 and $75.00, 67% of the time. Another $60.00 stock with an implied volatility of 10% would have an anticipated price range of $54.00 to $66.00. There is no need to look up or calculate implied volatility stats because we can glean the degree of risk by looking at our option returns based on our cost basis. I set a goal for initial 1-month returns for near-the-money strikes of 2-4% per month. I will go a bit higher in bull market environments (up to 6%). In my mother’s more conservative portfolio, I set a goal of 1-2% for 1-month returns. Below is a screenshot of a section of the BCI Premium ETF Report for exchange-traded funds. Pages 7-8 shows the implied volatilities which can be compared to that of the overall market (S&P 500):

With the IV of the S&P 500 at 7.76 (red arrow), the screenshot shows some ETFs having slightly less than double that implied risk (purple) and some triple to quadruple the risk (brown) of the S&P 500. Investors with a low risk-tolerance will tend to avoid securities like Deutsche X-trackers Harvest CSI 300 China A-Shares (NYSE:ASHR), iShares MSCI Italy Capped (NYSE:EWI) and iShares MSCI Emerging Markets (NYSE:EEM).
“Moneyness” of out-of-money strikes
When we are bullish on the market and on a specific stock, we favor out-of-the-money strikes which generate time value returns and allow for additional share appreciation up to the strike price. Frequently investors will simply decide based on the strike that is above but closest to current market value. These strikes will tend to generate the highest initial returns but offer little or no opportunity to take advantage of share appreciation. In August 2017, Exact Sciences Corp. was trading at $38.66 and we viewed an option chain for the $39.00, $40.00 and $41.00 out-of-the-money strikes. Here are the calculations generated by the multiple tab of the Ellman Calculator:
Looking at the return-on-option column (ROO), the 5.0% ROO for the $39.00 strike seems like the best choice. However, if we look at the “Upside Potential” column (highlighted in yellow) we see additional opportunities to generate cash. The deeper out-of-the-money strikes offer lower ROOs but higher upside. In a firm bull market, we have an opportunity to generate a 1-month return of 8.6% (2.5% + 5.1%) for the $41.00 strike whereas the $39.00 strike will generate a maximum of 5.9% (5.0% + 0.9%).
This is a valuable instructive scenario as the IV of the underlying is similar for the 3 strikes and Theta (time value erosion) will also be comparable for all 3 strikes but yet the premiums are different. This relates to Delta which will be different for each strike. Near-the-money strikes have higher Deltas than deeper out-of-the-money strikes and this accounts for the price difference. Implied volatility is a critical factor in our covered call writing decisions but not the only factor.
Discussion
Implied volatility is a factor we must consider when evaluating the underlying securities we choose. Each investor should set a percentile range for initial returns based on overall market assessment (bearish to bullish), personal risk-tolerance and chart technicals. IV is a critical but not the only factor that determines our option premiums.

Summary
IBD: Market icorrection
GMI: 1/6- Sell signal since market close of February 7, 2018
BCI: Due to the market volatility, I will be selling only in-the-money calls until market volatility subsides. I remain bullish on the economy and the market moving forward.
WHAT THE BROAD MARKET INDICATORS (S&P 500 AND VIX) ARE TELLING US
The 6-month charts point to a slightly bearish outlook. In the past six months, the S&P 500 was up 6% while the VIX (29.06) moved up by 160%.
