# Institutional 13F Tracker (SentiSense) See who owns a stock and how the big money is repositioning. This skill reads institutional ownership from SEC 13F filings through the read-only SentiSense API: the top institutional holders for any ticker, aggregate buying and selling per stock, activist positions, and a full portfolio for any manager (from Berkshire Hathaway to the largest index funds), with quarter-over-quarter change types (new, increased, decreased, sold out) across thousands of filers. Read-only educational data interface. Output is informational context, never a personalized buy or sell recommendation. ## When to Use Reach for this skill when the question is about institutional ownership or 13F positioning: - "Who owns $NVDA?" or "top institutional holders of $TSLA" - "What did Berkshire Hathaway buy and sell last quarter?" (a manager's whole portfolio) - "Is institutional money accumulating or distributing $AAPL?" (aggregate flows) - "Which activist funds took new positions this quarter?" - "How did 13F ownership of $COIN change quarter over quarter?" This skill pairs naturally with `politicians-stock-tracker`: line up 13F accumulation against a congressional purchase on the same ticker. Convergence across sources is the high-conviction read. Do not use it for order entry, portfolio management, or personalized advice. It has no write, trading, or wallet surface; every endpoint is a GET. ## What this data actually is (read before interpreting) - **13F i
