What price range does the model give BA?

The calibrated range for BA over 63 trading days is $175.92 to $228.75. It sits around the last close, and its width comes from the volatility that BA's own options imply (37% a year), calibrated weekly against realised prices (n = 3,330 past valuations, refreshed 26 Sep 2026). Ranges built this way held the price 60% of the time at this horizon. The fair value is the model's opinion and rides beside the range. It is not the centre of it.

The model's own simulated range, from the 20th to the 80th percentile of its runs, is $111.20 to $209.76. In 31% of the simulations the fair value came out above the price the model ran on.
