"Buy the Rumor, Sell the News" Isn't Always the Same Trade Twice
The phrase gets used as if it's a reliable pattern. In practice, it describes two genuinely different market behaviors that just happen to share one catchy name.
"Buy the rumor, sell the news" describes a specific sequence: an asset rallies in anticipation of an expected positive event, then sells off once that event actually happens — even though the news itself turned out to be genuinely good. The explanation usually given is that anticipation had already priced in the good outcome, so the actual announcement leaves nothing new to react to, and any traders who bought purely on the anticipation take the opportunity to sell into the news itself.
The pattern is real often enough to have earned its reputation, but it isn't a universal law — plenty of good news still produces a rally on the announcement itself, particularly when the actual result beats even the most optimistic pre-event expectations, or when the market genuinely hadn't priced in the event as confidently as the phrase assumes.
The distinction that actually matters is how much of the good outcome was already reflected in price before the news arrived. An event everyone was confident about, with an asset that already ran hard into the announcement, fits the classic pattern; an event with genuine uncertainty about the outcome, where price hadn't moved much beforehand, is a fundamentally different setup even if the eventual news is equally positive.
Treating "sell the news" as an automatic rule regardless of how much anticipation was already priced in is how the pattern gets misapplied — the phrase describes a specific mechanism, not a guarantee that applies to every piece of good news equally.
