Subject: Re: A/B ratio/ Buybacks/ Put Sell?
I wondered if you had figures of some sort about such.

I don't have anything numerical. Like you, just the observation that sudden relative-to-market drops are sometimes brief things.
On the other hand, we've had two relative-to-market gaps down recently that saw the trend continue, both in early May, so it's not much of an observation.

Long stretches of slow relative-to-market slides are common. Today's weakness, though sudden, is basically on the four month trend like that.

I have been net short Berkshire in this stretch, and long some other stuff, and it has been very pleasant for me. Beating the market nicely this year, while being 2/3 in cash.
