The reading in brief

As of October 8, 2026, BBY, a Specialty Retail name in the Consumer Discretionary sector, closes at $88.40 against a model fair value of $77.75, so fair value sits below the price by −12%. The published 21-session view leans down, with an expected return of −1.98% and a probability of a rise of only 7%, a firm lean by the model's own measure. Still, the band from −18.3% to +14.3% is wide and spans both signs. The 63-session view, at −2.39%, points the same way. The reading comes in a strong risk-off market regime. The record on this name is long, at 257 matured 21-session forecasts, yet only 46% of them matched the direction, which tempers the strength of the lean.

InsightModel output
What it meansThe belief leans down (−1.98%) and its own P(up) is 0.07: a negative average and a worse-than-even chance of rising.
What history saysThe expected return ranks higher than 64% of 1,303 names today. On settled outcomes a top-decile belief has been right 51.0% of the time against 51.7% for every name. Proven measures read outside the belief: 7 — favouring it, 5; leaning against it, 1. The strongest of them, Run vs industry · 3 sessions, held its ordering in 32 of 32 years since 1995.
How to use itRead the rank and the range before the number; the band legs, not the average, say how wide the outcomes run.
