Every December, the stock market creates a powerful pocket of opportunity through a little-noticed force known as tax-loss selling. This practice involves investors selling their losing stocks to offset capital-gains taxes. In 2025, the effect was especially strong after a year filled with U.S. market gains. As a result, the stocks of many fundamentally sound companies were pushed lower — not because their businesses deteriorated, but simply because investors were tidying up their tax books. That selling pressure tends to fade once the calendar flips.
As 2026 gets underway, these stocks could begin to recover as bargain hunters and long-term investors step back in. That rebound is rarely instant. In fact, it tends to unfold gradually over several weeks as value investors accumulate shares that were unfairly punished by year-end tax strategies. That said, MarketWatch used a disciplined screen to identify some of the most attractive opportunities and separate true quality from struggling businesses.
