What is a market rally?

A rally is a fast, sustained price rise, in a stock or the whole market: days or weeks of concentrated gains.

Rallies can spring from news (record earnings, central bank pivots), technical positioning (short squeezes) or simple mood shifts. The famous "Santa Claus rally" is the statistical tendency of markets to rise in the year's final sessions.

Beware "bear market rallies": violent 10–20% climbs inside bear markets that suck optimists in before new lows. 2008 had several before the true bottom.

Concrete example

In November 2020, on Pfizer's vaccine announcement, the stocks hit hardest by Covid rebounded 20–50% in days: a textbook rotation rally.
