“Priced In”, Explained: How Expectations Move Markets Before Events Do

Foundations

“Priced in” is the most important phrase in market commentary and the least explained. It means the market has already adjusted prices for a piece of information or an expected event, so when the event actually happens, prices may not move at all. It is why good news can be met with silence and bad news with a rally: the market is not reacting to events, it is reacting to the DIFFERENCE between events and what it expected.

How expectations get into prices

Markets are forward-looking machines. Every trader with a view about next month’s rate decision or next quarter’s earnings expresses it today, by buying or selling now. Those trades move prices until, in aggregate, the price embeds the consensus expectation. By the time an anticipated event arrives, the price already contains it; only the gap between outcome and expectation is new information.

The tell-tale patterns

Pricing-in explains the market behaviours that most confuse newcomers. “Buy the rumour, sell the news”: an asset rallies INTO an expected positive event, then falls when it happens, because the last optimist has already bought. A company beats earnings and drops: the whisper number was higher than the published consensus. The Fed hikes and bonds rally: the hike was priced, and the Chair’s dovish tone about the NEXT move was the surprise. In each case the event was old news to the price.

How to use the idea

Before treating any scheduled event as a market catalyst, ask what is already priced: consensus forecasts, futures-implied probabilities of central bank moves, options pricing of the expected move. The question that matters is never “will the news be good?” but “will it be better or worse than what the price assumes?”. Most of our analysis is, at bottom, an attempt to answer that question before the market does.
