The three signal families
1) Dollar movers / losers
Best for absolute capital at work. Example: Berkshire +GOOGL ~$10.01B; Berkshire −CVX ~$2.38B; TCI −MSFT ~$7.11B; SoftBank −TMUS ~$3.69B among top 13F Q1 dollar losers.
2) % of disclosed AUM
Best for portfolio impact inside a manager’s 13F book. Example: WindAcre +ROP ~+13.65% AUM; SoftBank −TMUS ~−32.31% AUM; WindAcre +ROP +13.65% AUM
3) Manager counts (increasing / decreasing / entering / exiting)
Best for breadth and contested ownership patterns. Example: AMZN 140↑ / 128↓; MU 43 managers entering; Mag7 names topping both sides.
When to prefer which signal
| Question | Prefer | QuantyFight example |
|---|---|---|
| Who moved the most money? | Dollar movers/losers | Berkshire GOOGL / CVX |
| What hit a concentrated book hardest? | % AUM | SoftBank TMUS −32.31%; WindAcre ROP +13.65% |
| Is interest broad or narrow? | Manager entering/increasing counts | MU 43 entries; AMZN 140 increases |
| Is ownership contested? | Increasing and decreasing counts | GOOGL 73↑ / 103↓ |

Caveats to keep visible
13F is delayed; longs only; disclosed book ≠ full firm AUM; share-class and reporting transitions can create large “moves.” Movement rows are research starting points — not trade recommendations. See Membership for deeper catalog access.
