For BRKB shares in a traditional account my basis is too level to sell unless BRK became extremely overvalued. Even at $540 recently, not tempting enough to sell. So selling covered calls is just trying to juice returns a small bit. But it adds up to a pretty good amount of money each year.
I do something similar with shares of things that I've owned for decades, where the basis is essentially zero or near zero. For example, over the last two years, I've sold UNH puts periodically, not anywhere close to being in the money, but certainly at prices where I would be delighted to buy more shares. So far, they've all expired worthless and provided an extra ~3.9% of yield in addition to the usual 2-3% dividend.
