These move in the same direction about 61% of the time
Their swing sizes only faintly line up (~5% of the pattern is shared).
A real but noisy link — useful as context, risky as a standalone signal.
Both lines start at the same point — easy to compare when growth rates are similar.
What to Watch
Holds in both up and down markets
The relationship is similar whether prices are rising or falling — reliable in both directions.
AI Analysis
With 61% of periods in sync, Dell and Lyft may be linked through their reliance on technology trends and consumer spending patterns, where shifts in demand for tech products can influence ride-sharing services. The data confirms this connection, as both stocks have shown correlated movements, suggesting shared market influences rather than randomness. Investors should closely monitor consumer spending reports, as these will likely impact both companies' performance. Not investment advice.

Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.

No-shift correlation, matching the main time-series chart above.
Peak shift
No shift
+22%
A non-zero peak suggests one series lines up better when shifted against the other.
Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
Do They Crash Together?
How these series behave when markets are rising, falling, or diverging. A correlation that holds in drawdowns is very different from one that only works in rallies.
