AAPL today looks like MMM did in Apr 2021
AAPL's chart over the last 30 trading days is a 88% shape match for MMM in Apr 2021 — its closest historical analog across a decade of market data. In the 15 trading days after that point, MMM went essentially flat.
The forward path is MMM's actual history after that date — not a prediction for AAPL. A close shape match is a starting point for research, not a signal. Different stocks with similar charts can do very different things next.
How we find the twin
We embed AAPL's recent daily chart into a 256-dimension shape vector and search millions of historical chart windows for the nearest match by shape, then re-score the finalists on the exact window shown so the lines actually overlap. The match is amplitude-aware, so it's a real twin — not just "both went up."
