A breakout to a new 52-week high on heavy volume means there are no longer any holders sitting on losses above the price, so overhead supply is gone. Momentum traders buy such breakouts and trail a stop below the breakout day's low. This screen lists stocks on the London Stock Exchange that set a new 52-week high today, up more than 2% on at least twice their 21-day average volume, heaviest volume first. LSE prices are quoted in pence, and the list skips thinly traded shares.
