Among technical indicators, which moving average crossover is most effective for predicting market turning points? The golden cross, where a short-term moving average (e.g., 50-day) crosses above a long-term moving average (e.g., 200-day), often signals a bullish reversal, confirmed by rising volume. Conversely, the death cross, when the short-term average dips below the long-term average, hints at a bearish shift, especially with increased selling pressure. While the 50-day/200-day pairing is widely watched, faster crossovers like the 20-day/50-day can catch shorter-term turns, though they risk more false signals. Effectiveness depends on market conditions—trending markets favor slower crossovers, while choppy markets suit faster ones. No single crossover is foolproof; combining them with other indicators like RSI or MACD enhances accuracy. Timing and context are key to spotting true reversals.
