Thats the great thing about the stock market, if there were no stupid daytraders, then it would be real hard to make insane amounts of money :-)
Stupid daytraders use stocks like gambling - they canīt go to the casino, so they invest in stocks using the same science to pick stocks as they would at the roulette table picking black or red:
"I got a good feeling about red - hold my rabbit foot - I will buy me some Acacia stocks"
