What this lesson is about

Most analyst upgrades happen after a stock already moved. Which means they're often nearly useless for predicting what happens next.

Part 1 of 2

Studies show a clear pattern with analyst ratings: most upgrades happen after a stock has already moved significantly, not before. This doesn’t mean analysts are bad at their jobs. It highlights what a rating is and isn’t.

A sell-side research analyst covers a group of stocks, usually in one sector. They publish a rating (Buy/Hold/Sell), a price target, and detailed reports on earnings, industry trends, and specific company news. These reports are genuinely helpful for understanding a business, its financials, and its competitive position.

Insider Angle: Here’s where it gets tricky: analysts work at banks that want investment banking business from the same companies they cover. This creates a real disincentive against harsh "Sell" ratings for potential clients. Also, analysts often react to confirmed news. Like an earnings beat or a new contract. Rather than predicting it. So, many rating changes are more about confirming a move that already happened rather than signaling what's next. Buy ratings far outnumber Sell ratings across the industry. Not because most stocks deserve a Buy, but partly due to this structural incentive.
