What the pros own — every quarter.
Ten of the world's most-followed funds, every quarter, side by side. See what they all bought before it's the cover story.
Consensus is information.
When Berkshire, Bridgewater, and Citadel all initiate a position in the same stock in the same quarter, that's signal. The filings are public — but the data lives in XML, the tickers are coded as CUSIPs, and the punditry takes three weeks to catch up. Most retail traders never look. The ones who do find it weeks late, after the price has already moved.
What you get with Mantis.
Ten institutions, every quarter, in plain English. Berkshire Hathaway, Bridgewater, Renaissance Technologies, Citadel, BlackRock, Vanguard, ARK, Point72, Two Sigma, D.E. Shaw. Each filing lands in the app within hours of being published — already parsed, with tickers resolved and dollar weights normalised.
Open the Overlaps tab and pick any two or more funds. You see only the stocks they all hold. Sort by combined dollar weight to find the highest-conviction consensus names in the market. That's the question most traders never ask cleanly: 'What do the smartest people in the room agree on right now?'
Tap a name and you jump straight to the symbol — chart, fundamentals, your existing thesis if you have one logged, your live alerts if you're watching it. A consensus position you didn't know about becomes a candidate watchlist add in three taps.
How it fits your day.
You open Whale Tracker once a quarter, right after filings season — early February, May, August, November. Twenty minutes, end-of-day. You scan the Overlaps tab for the consensus names you don't already hold. The ones that line up with theses you've been kicking around become next quarter's watchlist additions. The ones you already own quietly validate that you were early. It's the kind of research a fund's junior analyst spends a week on and writes a memo about. You get the memo on your phone.
