TV is another way to expose yourself to the stock market. No question, CNBC is the most popular channel. Even turning on CNBC for 15 minutes a day will broaden your knowledge base. Don’t let the lingo or the style of news intimidate you, just simply watch and allow the commentators, interviews, and discussions to soak in.

Recommendations rarely yield profitable trades.
