The sheet gives no reason for the move. The calibrated range over 63 trading days is $280.21 to $413.20. It is built from the fair value, since there is no live options data for the stock, and it is calibrated weekly against realised prices (10,454 past valuations, refreshed 31 Oct 2026). Ranges built this way held the price 60% of the time at this horizon. The model grades the evidence behind this valuation as low, so no verdict is shown. For insurers, the grade looks at the comparable companies, the spread of outcomes and whether the valuation methods agree. It does not say whether the fair value is right.

The model compares the company with two companies that have a fair value of their own on the site: American International Group, Inc. (AIG) and The Hartford Insurance Group, Inc. (HIG). Two more, Arch Capital Group Ltd. (ACGL) and Genworth Financial, Inc. (GNW), have no verdict on this date.
