Boycotts only work for goods with fixed demand. The stock market is designed to be maximally responsive. You can't boycott a stock for moral reasons; you're effectively just donating money to people with no moral qualms.

You have to realize that the stock market is an engine for predicting profit. If you're boycotting something for reasons that are not represented in profit, then all you're doing is turning yourself into the sort of damage that the stock market is best at routing around. The only way to punish companies is to impact their bottom line, and boycotting their stock does not have that effect unless you control enough of the market that the rest can't pick up the slack, and if you don't have that influence then the effect will be negligible.

If, as they say, the market can stay irrational longer than you can stay solvent, then certainly the market can stay rational longer than you can stay obstinate.
