1 of the 3 priced multiples above sits in the richer half of its band. Each priced multiple is read against this stock's own history where a five-year range is on file, so the question is whether today is dear for this name rather than for the market. The multiples are computed separately from the quote above and are not re-priced as it moves, so they can lag it.

Skip it if any of these is you
You can't sit through -38%
That is this name's deepest measured fall, on 93% annualized volatility. A drawdown of that size is normal here, not exceptional.
You want income
A 0.73% yield is a rounding error against cash. This is a capital-gains position.

Historical, point-in-time backtest of a cross-sectional screen (135 months, 2013-2026), gross of trading costs. The equal-weighted base effect is marginal (t 1.84); statistical significance relies on the dependency weighting (t 2.02). Validated on monthly rebalancing; served daily on the same 21-bar horizon.
