What happenedThe run of 31 Oct 2026 moved the fair value from $324.59 to $310.74 (-4.3%). The stock's own trading multiple fell with its price, and the fair value follows it in part: most of the move.

What the model makes of itThe price of $294.81 is 5.4% below it: Fairly valued, on a medium evidence grade.

What's nextReports on 4 Nov 2026. Options expiring after the report price a move of about 7% either way. The next weekly run is on Saturday 7 Nov 2026.

What price range does the model give CLH?

The calibrated range for CLH over 63 trading days is $273.49 to $323.29. It sits around the last close, and its width comes from the volatility that CLH's own options imply (25% a year), calibrated weekly against realised prices (n = 6,661 past valuations, refreshed 31 Oct 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 $230.56 to $411.81. In 53% of the simulations the fair value came out above the price the model ran on.
