Frequently asked questions
What is the January effect?
It's the historical tendency for stock prices, especially small-cap stocks, to rise in January, often attributed to a rebound after year-end tax-loss selling.
Why does the January effect happen?
A common explanation is that investors sell losers in December to harvest tax losses, then repurchase in January, pushing those prices back up.
Is the January effect reliable?
It's a documented seasonal anomaly, but it has weakened over time and doesn't occur every year, so traders treat it as a tendency, not a rule.
