I'm not Jim, but here is a comparison of holding BRKa without any trading (LTBH) from 10/14/1976 to the present, and using Nasdaq NH-NL to move to cash during risky periods, and using my own rendition of the Sell in May concept. A key thing to look at is the % of Time invested.

The Nasdaq NH-NL has way too many trades for my liking, but the Sell in May has a maximum of two trades per year.
