What is tax-loss harvesting and how does it influence stock price behavior in Q4?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Tax-loss harvesting is selling losing positions before year-end to realize capital losses that offset gains for tax purposes, which can create temporary selling pressure on underperforming stocks during Q4.
How it works
Investors and analysts sometimes watch for a 'January effect' bounce in previously tax-loss-sold stocks as harvesting-related selling pressure subsides after year-end.
An example
A stock down 40% for the year might see additional selling pressure in December from investors harvesting losses, followed by potential stabilization in January.
Risk & limitations
Tax-loss harvesting strategies have IRS wash-sale rules limiting repurchase within 30 days, and relying on seasonal patterns is speculative since they don't repeat consistently every year. This describes U.S. federal rules only; Canadian and other non-U.S. investors are subject to different tax/regulatory regimes (e.g., CRA rules, TFSA/RRSP treatment) and should consult a local tax professional.
Examples are hypothetical, not trade recommendations. US contract and regulatory references do not automatically apply in Canada. Rules, margin requirements and broker policies can change; confirm them with the relevant authority and your broker.
