Do SPY and YM Move Together on 5-minute Charts?
Educational reference. Measured from recorded market data through September 4, 2026. Not a forecast.
SPDR S&P 500 ETF and E-mini Dow are often assumed to move together. This measures it against 3,518 time-aligned 5-minute bars over the last 45 days — no opinion, just what the two actually did.
| Bars where both moved | 3,374 |
|---|---|
| … and moved the same direction | 2,598 (77.0%) |
| Correlation of bar-to-bar changes | +0.719 |
A coin flip would be 50%. At 77.0% and a correlation of +0.719, these two have a clear tendency to move together on this timeframe.
Where the relationship breaks down
Prices moving together does not mean everything else does. The indicator pages below measure each reading separately — and momentum, trend strength and volatility frequently disagree even when price does not.

How this was measured
Every 5-minute bar recorded for both instruments in the last 45 days was aligned by timestamp. Bars where either did not move are excluded from the direction figure, since a flat bar agrees with nothing. Correlation is measured on bar-to-bar changes, not on price levels — two markets can both drift upward for unrelated reasons, and correlating levels would call that a relationship.
