Trend-following ETF investors hold only funds in long-term uptrends, a simple rule that has kept many out of the worst bear markets. This screen lists exchange-traded funds on the London Stock Exchange trading above their 200-day moving average, with the 50-day average above the 200-day, the price within 5% of the 52-week high and a six-month gain above 15%, ranked by six-month performance. LSE prices are quoted in pence, and the list skips thinly traded shares.
