This screen lists stocks on the London Stock Exchange whose 14-day Relative Strength Index (RSI) is above 70. A reading over 70 means the price has risen fast and may be stretched, which can precede a pullback. In strong uptrends, though, RSI often stays above 70 for a long time, so momentum traders read it as strength while swing traders use it to take profits. LSE prices are quoted in pence, and the list skips thinly traded shares.
