Golden Cross: The Regime-Change Signal

The signal

The 50-day moving average crosses above the 200-day. That's the whole thing — and its reputation is earned: most of history's great bull runs happened *after* a golden cross, and most devastating declines happened under its inverse (the death cross).

What it really tells you

Not timing — regime. A golden cross says the medium-term tide has overtaken the long-term tide; the environment now statistically favors longs. It will never catch the bottom (it can't — it's an average of an average), and it will occasionally whipsaw in sideways markets. Its power is keeping you on the right side of big moves for their long middle.

Our scanner's rules

• Fires only on a fresh cross (within the last five sessions) — an old cross is old news.
• Confidence rises with trend strength (ADX) and volume.
• Entry: current price. Stop: below the recent lows or the 200-day line, whichever is tighter after the volatility check. Target: 2R, but this is really a *hold-while-it-works* signal.

Common mistakes

• Treating it as a precision entry: pair the regime signal with a tactical entry like the pullback to 21-EMA.
• Ignoring it on stocks you're bottom-fishing: buying under a death-cross regime is swimming against a documented current.
