Buy the rumor, sell the news
Buy the rumor, sell the news describes a market pattern in which prices rise ahead of an expected event and fall once it actually happens.
The saying comes from traditional markets. Traders buy while an event is anticipated, such as an upgrade, a listing or an approval, pushing the price up. By the time it happens, the good news is already priced in, early buyers take profits and there are few new buyers left, so the price often drops even though the outcome was positive.
Crypto has many examples. Major network upgrades, token listings on large exchanges, halvings and ETF approvals have all been followed at times by sharp declines after a run-up. Bitcoin fell for several weeks after the first US spot ETFs began trading in January 2024, before rallying to new highs later.
The pattern is a tendency, not a rule. Some events trigger further gains when the actual impact exceeds expectations, and many traders who sell every piece of good news miss sustained trends. Positioning data such as funding rates and open interest can show how crowded the pre-event trade has become.
Example
A token climbs 80% in the month before its listing on a major exchange. On listing day it jumps briefly, then falls 30% over the next week as early buyers take profits.
