SMA Crossover for US500 (S&P 500)

The classic golden-cross / death-cross signal — slower than EMAs, fewer false positives.

Why SMA Crossover Works on US500

The SMA crossover uses simple moving averages instead of exponential. The signal is slower to fire (good — fewer whipsaws) but slower to exit (bad — bigger giveback). The 50/200 SMA cross is the textbook "golden cross" signal used by every CNBC anchor for a reason: on daily charts of major indices, it actually works.

The S&P 500 (US500) is the global benchmark equity index. Strong long-term uptrend with regime shifts; momentum and trend bots dominate, mean-reversion works in QE periods only.

Equity indices reflect aggregate corporate earnings, sentiment, and Fed policy. They trend more cleanly than individual stocks and gap less than commodities.
