The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

How has that done versus just buying and holding it?

It appears to have done a bit better than B&H. At the end of 2023 the stock went from $35 to $480, so with B&H $35K would compound to $480K.

The growth of the options strategy would depend upon the percentage size of the individual purchases. I haven't used the Kelly criterion to calculate the optimal percentage size, but if you used 10% of your cash for a position then the first year each purchase would be $3.5K worth of calls.

At the end of 2017 the $35K would have grown to $52K. In 2018 if you kept with the 10% rule then each call purchase would be for $5.2K. In 2019 that would increase slightly to $5.7K each time, growing the account to $82K by the end of the year. Each year saw growth, and for 2023 the position size would be $31.1K. Total at the end of 2023 would have been $540K, beating out the $480 with B&H.

I'll look into the optimal Kelly criterion size.
