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.
The investors who stay calmest during market volatility aren't the bravest. They hold passive investing products that don't ask them to make decisions. Research from Morningstar, Vanguard, and academic studies shows that product design, not temperament, explains why passive fund investors trade less, hold longer, and capture more of their returns. UK flow data from the current Iran-driven selloff confirms the pattern in real time.
