WHY Flow and price both inside normal ranges (-1.5% on the week) — no crowding signal in this name today.
Momentum from daily closes. Short interest is FINRA’s twice-monthly count of shares actually held short (a standing position), which is a different thing from the daily flow above — days to cover is that position divided by average daily volume.
FLOW VS PRICE — LAST TEN SESSIONS
▬ short-side flow share (left axis) ┄ price (right axis)
Five days of short-side flow share (and close). Red = heavier than this name’s own monthly norm, green = lighter.
HOW WE READ UNP
Every trading day, FINRA publishes how much of UNP’s volume traded on the short side. We rank today’s share against this name’s own trailing month (60 sessions of history): today sits at the 27th percentile. Flow is then read with price — heavy short flow into a falling price is pressure; the same flow into a rally is mostly market-maker machinery. Days with volume shocks (earnings, news) are flagged post-shock and never read as clean signals. The result is the state badge above — a description of the crowd, never a buy or sell call.
