How to read a super investor’s portfolio in 5 minutes

Five quick checks that tell you more about an investor’s portfolio than the full holdings table.

1. Start with concentration

Look at how much of the portfolio sits in the top 10 positions. A high share (above 80%) means a few big, high-conviction bets. A low share means a diversified approach where any single stock matters less.

Our “behaves like N equal bets” number does the maths for you: it converts the position sizes into an equivalent number of equal-weight holdings.

2. Check what changed

New positions and big adds show where conviction is growing. Full exits show where it ended. Small trims are often just rebalancing.

3. Look at sector tilt

The sector chart shows the investor’s worldview: lots of financials and energy points to value, lots of software and semiconductors points to growth.

4. Watch the history

One quarter is a snapshot. Two years of history show whether a position is a long-term core holding or a short-term trade.

5. Compare with peers

When several unrelated investors own the same company, that overlap can be a useful signal. Our similarity score shows which portfolios look most alike.
