On Jun 23, 2022, BRKB was $267.52, and over the short-term, the next ~6 months, there was indeed an opportunity to buy it at a lower price two times. Each time for about $3 lower, once on Sep 26, and once on Oct 12.
But $3 lower on a $267 stock is not really a “much better” price, it’s only a tiny bit better.
I’ve written some Jan '23 puts on BRKA with the hope that they will be exercised and allow me an entry point below 300. They expire in 17 days from now. I would have preferred buying at $267, but was too fearful at the time.
