The percentage of stocks trading above their 200-day moving average is one of the most reliable structural breadth indicators. Here's how to read it, what levels matter, and how it fits in a daily routine.
Price can be deceiving. An index can reach new highs while a growing share of its components quietly break down beneath their long-term moving averages — until the weight of that internal deterioration finally drags the index itself lower. The percentage of stocks above their 200-day moving average is one of the cleanest ways to measure that internal structural health in real time.
The 200-day simple moving average (SMA) is the most widely tracked long-term trend indicator in professional equity management. Institutional investors, fund managers, and systematic strategies all reference it as a dividing line between stocks in long-term uptrends (above the 200d) and those in long-term downtrends (below it).
Because it's so widely watched, the 200-day MA becomes a self-fulfilling reference: when a stock reclaims its 200d after a correction, buying interest tends to increase; when it breaks below, selling pressure often intensifies. Counting how many stocks in the universe are above vs. below this line gives a real-time read on the overall structural condition of the market.
The % above 200-day MA oscillates between extremes that correspond to different market regimes:
The WideRadar Breadth tab tracks both the % above 50-day and the % above 200-day MA. The two together tell a more complete story:
