A golden cross, the 50-day moving average crossing above the 200-day, is one of the best known long-term buy signals, and on ETFs it often marks a turn in a whole sector, country or asset class. This screen lists exchange-traded funds on the London Stock Exchange whose 50-day simple moving average crossed above the 200-day average on the last bar, ranked by six-month performance. LSE prices are quoted in pence, and the list skips thinly traded shares.
