Writing put options on a support level

As the following graph shows, the share price of Canadian Imperial Bank of Commerce (CM) has been trending downward since the beginning of 2018. When markets closed on Friday, March 23, CM was trading at $114.07. But as we can see, a price range of $112 to $114 has represented a support level from which prices surged twice. Furthermore, when the RSI (Relative Strength Index) and stochastic oscillator are at oversold levels, as they are now, it is not unusual to see prices rally more or less strongly.

Daily chart as at March 23, 2018 ($114.07)

Under such conditions, an investor who is still bullish about the market’s prospects in the medium term can profit from this weakness in the price of CM, writing puts to benefit should the stock stage a rebound or remain relatively stable. But if prices continue to fall, the investor should then be ready to buy the shares at the selected strike.


  • Sale of 10 put options CM 180518 P 115 at $3.50
    • Credit of $3,500


Profit and loss profile

By writing ten puts, CM 180518 P 115 at $3.50, we collect $3,500 ($3.50 x 10 contracts x 100 shares per contract). As the above table shows, this put option is currently $0.93/share in-the-money (strike of $115 – current price of $114.07) and contains $2.57 in time value ($3.50 – $0.93). This $3.50 premium per share provides us with protection against a drop of as much as 2.3%, i.e. to the breakeven price of $111.50 (strike of $115 – premium of $3.50), which is just under of the $112 support level. The strategy’s maximum profit is the total credit collected, or $3,500, and will be realized if CM closes at a price that is higher than or equal to the $115 strike on expiration of the options on May 18, 2018. This profit represents a 3.1% yield over 56 days, or an annualized yield of 20.5%. The static profit, i.e. the profit generated if the stock price remains unchanged, is $2.57 per share, for a total amount of $2,570 on the 10 contracts. The static yield is equal to 2.3% over 56 days, for an annualized static yield of 15%. At expiration, if the price of CM is still below the $115 strike, the investor will be obliged to buy 1,000 shares of CM at $115 per share, for a cost of $111.50 per share (strike of $115 – premium of $3.50). Any decline below this level will represent a loss on the strategy.



There are three ways to manage this position. The first is for the investor who is not afraid to buy the shares if the price falls. In this case, the position is held without intervening, and if the stock falls below the $115 strike on expiration, the shares are assigned and the investor simply buys them back. The second approach is to intervene if the price falls significantly below the breakeven price, by buying the put options written as a way of cutting the losses. The third approach involves intervening if the price of the shares rises significantly, by buying the put options written for 10% to 20% of their initial premium (in this case, for between $0.35 and $0.70). In the last two cases, other put options can be written, if this is still justified.


Good luck with your trading, and have a good week!
