Across 167 trading days, BA ground its way up +4862.0% — a mostly uphill ride that ends near its highs. It opens at $4.42 and closes at $219.32.
The standout move is to the upside: off its low near Oct 1987, BA put together a 8818.6% run-up into Jul 2019 — the longest climb in the game. It isn't all one way, though: the sharpest pullback along the route is a 67.6% drawdown, the deepest valley you'll drop into.
Day to day the terrain is violent — closer to a roller coaster than a road: 104 up days against 62 down (more up days than down). The steepest single faces are a +57.3% jump on Oct 1, 2022 and a -53.9% drop on Jan 1, 2020 — near-vertical walls you'll need to boost up or launch over. Its longest unbroken climb runs 10 days; its longest slide, 6.
If you want a breather, the calmest stretch sits around Oct 1990–Oct 1994; the roughest, most technical section runs Jan 2020–Jan 2024, where you'll earn most of your air. Put together, this chart rides as a white-knuckle run — ★★★★☆.
