Everyday before the market opens, I put a plus sign, minus sign or zero sign in front of every stock symbol I own. The plus sign signifies that I think the stock goes up today, the minus is down, and the zero sign is I don’t have a clue. I keep these sheets for several days comparing my predictions to the actual results. The cost of transactions is so miniscule that if I have a high confidence level that a stock is going down, I have to ask myself can I own this stock cheaper tomorrow. If so, why do I want to own it today?
