Why Stocks at 52-Week Highs Often Keep Rising
Conventional intuition says "buy low, sell high" — so buying stocks at highs seems backwards. But decades of research and trading wisdom show the opposite:
- Resistance is cleared: Every buyer from the past 12 months is now in profit. There's no "trapped longs" waiting to sell at breakeven. Selling pressure evaporates.
- Momentum attracts momentum: Trend followers and momentum funds systematically buy stocks making new highs. Buying begets more buying.
- Fundamental confirmation: Stocks don't reach 52-week highs by accident. Usually, earnings, revenue, or sentiment has improved to justify the price.
The research: George and Hwang (2004) found that stocks near 52-week highs significantly outperform stocks near 52-week lows over the next 6–12 months — even after controlling for other momentum factors. The 52-week high acts as an "anchor" that creates systematic underreaction in investor behavior.
The intuition trap: Retail investors often feel they "missed the move" when a stock hits new highs. Professional momentum traders recognize that new highs are the beginning, not the end, of many trends.
