Begin a market review by separating what happened from what you think it means. A price move is an observation. An explanation for that move is an interpretation, and may need further evidence.
Identify the coming events most relevant to the businesses you follow. Earnings, economic releases and company announcements matter differently to different positions. Avoid treating every headline as equally important.
Keep a short record of expectations before each event, then compare the outcome. Over time, that record can reveal where your judgment improves and where your assumptions repeatedly need work.
