your mixing up brokers and traders. my friend is a trader. he doesn't care about the company info of the stock he trades. all that matters to him is price, spread, bid, ask and volatility. it's all about the numbers. i ask him, what does so and so company do, he's like i have no clue, it brings me cash. brokers on the other hand actually research the company of the stock. traders do research as well, but very minimal.
