But think of how many made good money on the stock. It's a matter of knowing when to buy and when to sell. With BOMO it's a time to buy before news comes and the stock jumps 100% very quickly.
If someone tries to convince you to buy a stock they usually have a personal agenda to do so. Not because they are concerned about you making money but about convincing you to buy so they can make money. Same is true for those yelling sell.
