In our last blog publication, two put applications were discussed: traditional put-selling and the PCP (wheel) Strategy. In this week’s article, three more approaches will be reviewed, states Alan Ellman of The Blue Collar Investor.

Selling Cash-Secured Puts: Part II Methodologies

  • Buying a stock at a discount
  • Ultra-low-risk strategies
    • Delta
    • Implied volatility (IV)

Buying a Stock at a Discount: A Real-Life Example with Micron Tecnology, Inc. (MU)

The trade

  • 2/21/2022: MU trading at $90.10
  • MU is an eligible stock on our premium stock watch list
  • No upcoming ER for the contracts expiring on 3/18/2022
  • Set a limit order to buy at about $83.00 (example goal)
  • Sell a CSP with breakeven at about $83.00

The option chain (MU trading at $90.15)

The two possible (non-adjusted) trade results are a 3.09%, 45.15% annualized 25-day return or the purchase of the shares at an 8.54% discount ($90.15 to $82.45)

Ultra-low-risk approaches


Using a deep OTM put strike with a low Delta (-0.10, as an example) will create an approximate probability of success. For example, using a Delta of -0.10 will create an approximate probability of 90% that the option will not explain the money or wi intrinsic value and therefore will not be subject to exercise.

Implied volatility

Using a mean or at-the-money implied volatility will allow us to create an approximate trading range for the stock or ETF during a specific contract cycle.

Using IV to Determine Expected Price Movement Over a Contract Cycle

Since IV stats are based on one standard deviation and a one-year timeframe, the BCI Expected Price Movement Calculator can determine an approximate trading range for a specific contract cycle. In this example with DOW, we would sell a put with a breakeven price point near $54.93 and have an 84% probability that the put will not be exercised.


One of the outstanding benefits of selling cash-secured puts (and covered call writing, as well), is that the strategy can be crafted to meet several different strategy goals and appeal to investors of a wide range of personal risk-tolerances. The past two blog presentations highlight five such distinct pathways.
