News, Catalysts & Market Movers

Why news moves prices and how to filter the noise.

1. Why News Moves Prices — A stock price is the market’s best guess about a company’s future. News changes that guess, sometimes in seconds. Here is why prices react so fast, why they sometimes jump overnight and what volume tells you about a news move.
2. Expectations vs. Headlines — Great news can sink a stock and bad news can lift it. The reason is expectations: prices already contain what investors expect. Here is how to think about beats, misses and guidance, and why the reaction matters more than the headline.
3. Analyst Rating Changes — Wall Street analysts publish ratings and price targets on most large companies. Upgrades and downgrades can move a stock for a day, but they are opinions, not facts. Here is how to read them and how much weight to give them.
4. Economic Reports That Move Markets — Some days the whole market moves together because of one report or one policy decision. Here are the economic releases and events that matter most, when they come out and how they ripple into stock prices.
5. Company Catalysts: Launches, Deals & Approvals — A catalyst is an event that can change how the market values a company. Some are scheduled, like earnings or drug decisions; others arrive without warning, like a takeover bid. Here are the main types and how to handle the risk around them.
6. Separating Signal from Noise — There is more financial news every day than anyone could read, and most of it will not matter in a month. Here is a simple filter for deciding which headlines deserve your attention and which ones to ignore.
