Nobody can establish who first used the phrase 'evidence-based investing', and no regulator defines it. Robin Powell, who was given the name by Larry Swedroe in 2015 and is sometimes wrongly credited with coining it, sets out what it actually means: four tests of what counts as evidence, borrowed from a medical parallel that hit the same crisis twelve years ago. Including where he goes further than a global tracker, and why he holds that position less firmly than he used to.
Chasing last year’s top funds is seductive — and usually self-defeating. New evidence shows performance persistence is largely a mirage: most “winners” slip quickly, especially when markets get rough. Investors who keep costs low and own the market have far better odds of reaching their goals.
