Writing covered calls as a hedge against a slight drop in the shares of Sun Life Financial Inc.

As can be seen in the following weekly chart, shares in Sun Life Financial Inc. (SLF) have broken out of a range of $35 to $45 that has characterized trading since the beginning of 2014. In principle, $45 should now be a support level for SLF trades over the next few months. This sharp jump – we’re looking at an increase of close to 20% above the $45 upper bound in just a few weeks’ time – has allowed SLF to climb as high as $53.75.


Even though this upswing may have lasting power in the medium term, we should expect the price of SLF to fall slightly over the next few weeks, since both the RSI indicator and the stochastic oscillator are over 90. If the past, periods when both these indicators have suggested such extreme overbought conditions have been followed by price drops or by periods of price instability (see the above graph).


To take advantage of this scenario, investors could write one call for each 100 shares they own of SLF. With a closing price at $51.99, we will choose calls with a $52 strike in order to take advantage of the option’s eroding time value, which is at its highest for at-the-money options. In order to have a few weeks of flexibility, we will also choose options expiring on January 20, 2017.



  • Prior ownership of 1,000 shares of SLF (current price of $51.99)
  • Sale of ten call options, SLF 170120 C 52, at $1.25
    • $1,250 credit


Profit and loss profile



  • The position’s maximum profit of $1.26 per share or 2.48% (21.58% on an annual basis) will be obtained if SLF closes at a price greater than or equal to the
    $52 strike price upon expiry on January 20, 2017.
  • The static profit (the profit if the stock’s price is unchanged) is $1.25 per share or 2.46% (21.41% on an annual basis).
  • The breakeven price is $50.74, for a level of protection of 2.40%.


Further action


Since we are expecting the price of SLF to be stable or to drop slightly, we will buy back the calls at a price below or equal to $0.25, if we have the chance. If the price of SLF rises, a decision will need to be made on whether or not to buy back the call options we wrote, at a loss, based on whether or not we want to sell our shares. Over the next few weeks, we will take another look at this position.


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