The wife of my best client is a hotshot at IBM. She had a bunch of whuddayacall'em warrents? to buy in the 80s she got as a bonus. Exercise them, exercise them I say, and she actually listens to me. . . .and then buys something else back in the mkt which is down 25%. So instead of patting myself on the back, I am gritting my teeth, IBM being down "only" 10% or so.
Why is is that people never perceive that things can go down? The Wall St Journal has a story on a part of the brain being devoted to optimism, which I haven't read yet.
