Values above are the official-source snapshot for GSEO (3406) on 2026-10-30. We do not chase live quotes. Every trading day is frozen as its own point-in-time vintage, so a backtest reading this data sees only what was actually knowable that day, with no look-ahead bias. Missing values stay blank. Nothing is interpolated or extrapolated.

GSEO (3406): where today sits in the past year

Current value against the 2025-10-16 to 2026-10-16 range, built from 246 frozen daily vintages.

The marker is today's value; the faint tick is the one-year median. Every point in this range is the number as it was published on its own date, never a restated figure, so the percentile is what a reader on that day could actually have computed. Ratios at or below zero are excluded rather than treated as cheap. Tickers with fewer than 60 observed dates get no range at all.
That is this ticker against its own past. The other axis — where the same readings sit across the whole market on the same day — is directly below; the two can point in different directions, so both are worth reading. The full decile structure lives on the market P/E, P/B and dividend yield pages.

The same figures read against every other listed company on 2026-10-30, rather than against this ticker's own history.

Valid sample per metric: price / earnings 1,543, price / book 1,085, dividend yield 1,737. The three metrics are sampled independently rather than intersected, so the denominators differ — an intersection would turn every percentile into the percentile of whichever companies happen to disclose all three, a population nobody is asking about. Ratios at or below zero are excluded rather than counted as cheap; a zero dividend yield is kept because paying nothing is a real observation. The bar spans the 10th to 90th percentile, not the full range, because a handful of four-digit multiples would otherwise flatten every other company into the left edge; the percentile itself is computed on the full population and is unaffected.
The full decile structure behind these percentiles is on the market P/E, P/B and dividend yield distribution pages.
