The S&P 500 index is experiencing a broad-based momentum surge, with over 88% of its constituent stocks trading above their 20-day moving average, the highest level since August. Momentum indicators such as the Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD) are signaling strong buying pressure and broadening momentum across the index, not limited to megacap stocks. Despite a strong bounce in the index, the recovery in stocks trading above their 200-day moving average remains weak, indicating that the rally is still narrow and lacks full market participation. Analysts note the occurrence of the 17th breadth thrust since 1939, historically followed by higher S&P 500 levels over the next 130 to 190 days. While short-term dips are possible, growth stocks are expected to perform well over the next 9 to 12 months, supported by rare algorithmic buy signals and positioning that could trigger short-covering and fear of missing out (FOMO). Market breadth continues to improve with a healthy pullback considered normal after the recent rally.
