Exactly the book I came here to mention.

I used to write software for financial traders, so I know it's possible to make money by following second-to-second shifts in the market. But it's a zero-sum game, and I saw our traders take a lot of money from people who were responding to second-to-second shifts in the market.

These days I put my money in long-term investments and then look at them every few years. The other day I saw mention of the big market price jumps. I thought, "maybe now's the time to rebalance things?" And then I sat very still until the urge passed, because reacting to headline news strikes me as a great way to lose money.
