Bean Score Experimental
The Bean Score measures how far a stock's free cash flow yield has deviated from its own quarterly baseline, normalized by the stock's historical behavior. Between earnings dates, FCF is constant — so the score is purely a function of stock price. The levels below show at what prices AON would reach each dislocation threshold.
Dislocation Price Levels
Prices where AON's Bean Score would hit each σ threshold. Valid until next earnings report: 2026-07-24.
| Level | σ | Price | Signal |
|---|---|---|---|
| Deep Value | +2σ | $298.32 | Unusually cheap — potential buy zone |
| Value | +1σ | $306.65 | Cheap vs. own history |
| Fair Value | +0σ | $315.46 | Historical mean behavior |
| Expensive | -1σ | $324.79 | Expensive vs. own history |
| Deep Expensive | -2σ | $334.69 | Unusually expensive — potential trim zone |

Signal Accuracy Collecting Data
The Bean Score system is accumulating weekly data to validate signal accuracy. After 13+ weeks of history, this section will display win rates and average returns for each σ threshold crossing — answering the question: "When this score says cheap or expensive, does the price subsequently move in the expected direction?"
Theoretical framework — not backtested or forward-tested. The Bean Score uses trailing twelve-month free cash flow yield as a dislocation identifier. It measures whether the market has pushed a stock's yield unusually far from its own baseline behavior. These levels are reference points for identifying potential swing trade opportunities, not buy/sell signals. FCF values update quarterly with earnings; between reports, all movement is price-driven.
Dislocation Scores Experimental
Each score measures deviation from AON's own historical baseline — the same idea as the Bean Score, applied to different fundamentals. Positive means cheaper or more dislocated than this stock's norm. Scores marked σ are normalized by the stock's own variability; pp values are simple deltas from its recent baseline.
Theoretical framework — not backtested. These scores describe how unusual today's readings are for this specific company. They are starting points for research, not buy or sell signals. Annual-statement scores (buyback, accruals, FCF vs history) rest on only ~4 yearly data points and are deltas, not sigmas.
