Crossovers: Golden & Death Cross
When a fast average crosses a slow one — popular, lagging, and easy to misread.
A crossover happens when a faster (shorter) moving averageA line that smooths price into its underlying trend. crosses a slower (longer) one — a popular, simple signal that momentumBuying recent winners and avoiding recent losers. has shifted direction. Two have famous names.
- Golden crossA bullish signal when a short MA crosses above a long MA. (bullish) — a shorter MAA line that smooths price into its underlying trend.

- Death crossA bearish signal when a short MA crosses below a long MA. (bearish) — the shorter MAA line that smooths price into its underlying trend. crosses below the longer one, suggesting a downtrendThe prevailing direction of price: up, down or sideways. is setting in.
Crossovers are popular because they’re objective and easy — but never forget they are lagging signals. A moving averageA line that smooths price into its underlying trend. is built from past prices, so a crossover only confirms a move that has already happened. By the time a golden crossA bullish signal when a short MA crosses above a long MA. prints, a big chunk of the rally is often behind you. That’s the eternal trade-off: crossovers keep you on the right side of major trends and filter out noise, but they’ll never get you in at the bottom or out at the top. Use them to confirm direction, not to time precise entries.

FAQs
If crossovers lag, are they useless?
No — they’re just the wrong tool for precise entries. Their value is staying aligned with *major* trends and avoiding fighting the tape. Many systems use a crossover as a trend *filter* (only take longs when the fast MA is above the slow) rather than as a standalone entry trigger.
