Comeback stocks are names that fell hard and are now recovering fast. This list shows stocks on the London Stock Exchange trading more than 50% above their lowest price of the last year and up more than 20% over the last month, biggest monthly gains first. A strong rebound off a low can be the start of a new uptrend, or a short-covering rally that fades, so check the longer trend. LSE prices are quoted in pence, and the list skips thinly traded shares.
