There is no rule that says you always have to have action; yet that is perhaps the most disastrous of all the common errors we noticed. Rather than continually confronting the market on its own often inscrutable terms, stop and ask yourself what you know, whether what you know is enough to act upon, and how you are relating to it.
Maybe it is a period when the market’s personality conflicts with yours, or something in your extra-market life is hampering your ability to view stock action objectively, or, simply, perhaps it’s a time when the markets course isn’t clear to anyone. Then it is best to step aside. You owe it to yourself to find out exactly how ready and able you are to play, because it’s yourself you end up playing against.
