How Prior Moves compares
The stock-idea market splits into copy-trading apps, paid newsletters, and 13F trackers. Most charge a subscription and report only their wins. Prior Moves is a free research publication: it shows each tracked investor’s disclosed 13F holdings plus the names a per-investor model predicts they’ll buy next, publishes the misses alongside the hits, and never executes or custodies anything, you place your own trades at your own broker.
| Product | Price | What it is | Reports misses? | Predicts next buys | You hold the trades | Regulatory posture |
|---|---|---|---|---|---|---|
| Prior Moves | Free | 13F investor-mirror + per-investor model predicting next buys ~6 weeks pre-filing | Yes, publishes the full backtest, the misses, and a CI that includes zero | Yes | Yes, you trade at your own broker | Research publisher (not an RIA) |
| Dataroma | Free | Free web tracker of superinvestor 13F holdings | No | No, shows holdings after the filing | Yes, research only | Publisher |
| WhaleWisdom | $360/yr (Standard); free tier | 13F database back to 2001 + backtester | No | No, post-filing data | Yes, research only | Not a broker-dealer (publisher) |

| HedgeFollow | $120/yr ($10/mo unlock); free tier | Hedge-fund holdings, buys/sells, buy-price history | No | No, post-filing | Yes, research only | Publisher |

Prior Moves is a research publication, not an investment adviser. Nothing here is a recommendation to buy or sell. The backtested edge is small and its confidence interval includes zero, a directional signal, not a promise of returns.
