52-week highs and lows mark the year's price extremes. Learn why breakouts above the 52-week high tend to run and why 52-week-low breakdowns continue.
52-Week High / Low levels are the highest and lowest prices a stock has traded over the trailing year. Breakouts above the 52-week high have no overhead supply (every shareholder is in profit), so resistance is thin. Breakdowns below the 52-week low have no nearby support and tend to attract continued selling. Stocks within 2% of these levels are at a decision point.
