In the newsletter I use both covered calls and naked calls to increase the yield on the portfolio, which doesn’t actually show up in the results. Essentially because the portfolio is actively managed, with buy/sell price points, Calls can be sold at those price points that you wish to transact at.
Obviously “covered calls” are not a major concern, you hold the stock. Naked selling of Calls however are also not an issue as you will, if “called” want to purchase the stock [and collect the time value] at the Call price, and have cash available, as part of your cash balance for that purpose.
This adds approximately 10% yield/annum in a very low risk manner. Here is the current “open” trade utilizing both covered & naked calls.
