Retail Trader's Ruin: An Anatomy of Popular Signal Failure
Why popular trading tricks don't actually make money after costs
A systematic test of five widely promoted retail trading strategies—trend following, oscillators, candlestick patterns, volume rules, and calendar effects—found that four of them fail to deliver real profits after accounting for trading costs and statistical noise. The two remaining candidates, trend following and momentum, remain inconclusive because the data simply isn't large enough to settle the question either way.
Retail traders lose roughly $5 billion annually chasing strategies they find online or in trading books. This research provides concrete evidence that most popular signals don't work, which could spare individuals from sinking money into methods with no genuine edge. The rigorous testing framework also sets a higher standard for what claims about profitable trading strategies should actually prove before being promoted to the public.
