In general, if you polled all the doctors, I’d bet only a small percentage would turn out to be invested in medical stocks, and more would be invested in oil; and if you polled the shoe-store owners, more would be invested in aerospace than in shoes, while the aerospace engineers are more likely to dabble in shoe stocks. Why it is that stock certificates, like grasses, are always greener in somebody else’s pasture I’m not sure.
