Institutional Flow — S&P 500 Smart-Money Tracker
Where is the big money going? We infer institutional accumulation vs distribution from price & volume — not 13F holdings. These are derived signals (up/down volume, OBV, the Accumulation/Distribution line), updated daily.
S&P 500 (^GSPC)
Strong accumulationOver the last 30 trading days, price/volume signals suggest large players appear to be ACCUMULATING S&P 500 (^GSPC). This is inferred from up-volume vs down-volume, OBV and the Accumulation/Distribution line — it is NOT based on actual 13F holdings.
Sector flow — where smart money is rotating
11 sectorsHow we infer this (and what it is NOT)
These are price/volume-derived signals, not 13F holdings. Real institutional holdings are disclosed quarterly (Form 13F) with a 45-day lag — useless for knowing what is happening this week. Instead we read the footprint large players leave in daily volume.
- Up-volume vs down-volume: total volume on up-close days vs down-close days over the window.
- On-Balance-Volume (OBV): running total, +volume on up-days, −volume on down-days; its slope is the trend.
- Accumulation/Distribution line: Money-Flow-Multiplier × volume, accumulated — rewards closes near the high on volume.
- Pressure score (−100…+100): a blend of the three, mapped to the plain-English verdict.

FAQ
Are institutions buying the S&P 500 right now?
This tracker estimates it from price and volume. When the S&P 500 rises on heavier volume than it falls — and On-Balance-Volume and the Accumulation/Distribution line are trending up — large players are likely accumulating. When the opposite is true, they are likely distributing. The live verdict at the top of this page reflects the most recent 30 trading days.
Is this based on actual institutional holdings or 13F filings?
No. These are price/volume-DERIVED signals, not real holdings. 13F filings are reported quarterly with a 45-day delay, so they cannot tell you what institutions are doing this week. We use public daily OHLCV to infer the likely direction of large-money flow. Treat it as a sentiment proxy, not a holdings report.
What is up-volume vs down-volume?
We add up the trading volume on days the index closed higher (up-volume) and on days it closed lower (down-volume). Persistently higher up-volume suggests buyers are in control; higher down-volume suggests sellers are. Big institutions move enough size that their activity shows up in volume.
What is On-Balance-Volume (OBV)?
OBV is a running total that adds the day's volume when price closes up and subtracts it when price closes down. A rising OBV means volume is flowing into the market on up-days (accumulation); a falling OBV means the opposite. We chart it as the dashed 'institutional pressure' line.
What is the Accumulation/Distribution line?
For each day it computes a Money Flow Multiplier — how close the price finished to the high (buying) vs the low (selling) — and multiplies it by volume, then accumulates it. A rising line means buyers keep closing near the highs on volume; a falling line means sellers are closing near the lows.
Which sectors are institutions favoring?
The sector grid ranks all 11 SPDR sector ETFs (XLK, XLF, XLE, XLV, XLY, XLP, XLI, XLU, XLB, XLRE, XLC) by the same accumulation/distribution score, most-accumulated first, so you can see where smart-money pressure is rotating.
