I returned home from a weeks vacation and discovered on Friday morning that one of my investments (Phazar Corp, symbol ANTP) had doubled since I had last looked at it. While there is a slight chance that this was due in part to buyers with inside information that it’s likely to sell equipment used in new tsunami warning systems, it looks like most or more likely all of the buying came from momentum players whose connection with reality is more tenuous than normal. So if I had been following the stock instead of snowboarding, I would almost certainly have sold before Friday at a lower price. As it happened, I had the patience to postpone my sale until Monday morning, getting what I expect will prove to be an unreasonably good price, and also delaying taxes on the profits. This is not the first time I’ve seen evidence that slightly slower reactions to price changes would be profitable, but it’s certainly the most dramatic.
