Return figures use ADJUSTED closes — splits and dividends folded in, the same basis as the return tables below. The candles stay the traded price, so CNMD's own total-return path is drawn beside SPY (dividends added 0.4% over this window).
Volume shown as VALUE TRADED — close × volume, in USD. Split factors cancel in the product, so eras are comparable; the raw share count on today's split basis is behind “sh vol”.

A month’s return is its month-end close over the prior month-end’s, so a year’s figure is exactly the product of its twelve monthly cells — no separate annualisation, no resampling. A blank cell means no return exists for that month (the series had not started, or it is the very first month-end, which has nothing to be measured against). Blank is never zero.
Basis. CNMD is on the total return (splits + dividends) basis, SPY on the total return (splits + dividends) basis. Both columns are on the same basis, so the Δ column is a like-for-like difference.
Partial years. A year marked “ytd” or “part” does not cover the full calendar year: either the stored history starts inside it (the figure is measured from the first month-end present) or the data stops before December (the figure runs through the last stored close). The row’s own tooltip names the exact boundary. It is never dressed up as a calendar-year return.
End of day. These are stored end-of-day closes, and the window is anchored on the LAST stored bar rather than today’s date — so the newest row ends where the data ends. Nothing here is intraday.
