Trading at 59.6% of the 52-week range. Position only — a range position is not itself bullish or bearish.
Beta
52-week beta to the S&P 500 is -0.01. Higher = amplifies market moves; a risk measure, not a direction.
Relative volume
Relative volume 0.95x its 20-day average, 55th percentile since 1986. Participation behind the move; not a direction.
Earnings
Next scheduled earnings: 2026-12-10 (in 51 days).

Rank among covered stocks

This stock’s standing on each measure across the covered-stock universe (1 = highest) — a cross-sectional companion to the own-history percentiles above, computed from the same daily dataset. Ranks compare each stock’s current reading; the underlying own-history percentiles draw on histories of differing length (some reaching into coarser early-era pricing), so they are not strictly comparable instrument-to-instrument — read each alongside its own “since YYYY” basis in the table above.

Methodology

This page reports market statistics computed from daily closing data. It states figures and their historical context, and adds a Technical Assessment: a transparent, rules-based reading that puts those same statistics into plain language, including a factor sign tally — a count of how many scored factors read positive, negative or mixed, not a composite score or analyst rating. Every reading follows a fixed, published rule and traces back to the metrics on this page. It is informational and educational only — not investment advice, a price target, a forecast or a recommendation to buy or sell.

Full definitions for every metric on this page — how each is computed, over what window and on what basis — are on the methodology page.

Machine-readable: this page’s numbers and 252-session price history as JSON or the daily close and moving-average series as CSV — the figures above plus the series behind the chart, refreshed each session.
