I am very active in selling puts and calls on BRKB. For the most part I keep at least 50% or more cash to cover if I had to step up.

One difference is I sell way away from the strike price. Usually as low as offered and as high as offered.

My Jan 26 puts are as low as 190 and as high as 290.

My Jan 27 puts are 230.

I also have calls mostly covered by owned shares from $560 to $620 expiring Jan 26. The Jan $620 are naked. I continue to sell more weekly. If these become in play it would mean that I had made a substantial amount on my current BRKB shares as an offset. I consider the odds of BRKB hitting $620 by Jan 2026 as almost 0%.

Overall I try and generate 2-3% per year in premiums that I expect to expire. But I play way on the fringe.

Now I also recently started selling puts a little closer to the strike price. I have some $440 puts expiring tomorrow and each of the next 2 weeks. Then I have some $410 puts expiring over the next 2 months. If any of these are exercised than I am OK with that.
