How to use Whale Signal
A disciplined framework for reviewing institutional flow — not a substitute for your own judgment or professional advice.
When to review buy or sell ideas
The most useful time to study new ideas is after each 13F quarter is filed and has had time to settle — typically in the weeks following the reporting window, not in the middle of random market noise. Institutions report with a lag; Whale Signal organises that delayed snapshot so you can compare funds side by side in one place.
Many members find it helpful to revisit the list about once per quarter, then allow roughly a month for prices and narratives to stabilise before drawing conclusions or adjusting a personal watchlist.
What the whale score means
The whale score summarises how many respected funds hold a name, whether exposure is building or fading, and how price behaviour compares to the quarter. In general, a higher whale score points to stronger cross-fund overlap and a more coherent accumulation signal — which, in past data, has often aligned with ideas worth researching further.
It is a ranking aid, not a forecast. A high score does not promise returns; a low score does not mean a stock will fail. Markets change, filings are incomplete, and funds rebalance for reasons that have nothing to do with conviction.
A structured approach beats guessing
- 1
Wait for the quarter to settle
After each 13F filing window, allow several weeks for funds to report and for prices to absorb the news. Acting on day one is rarely better than acting with a clear picture.
- 2
Review the watchlists
Start with research buy and trim candidates where multiple tracked funds overlap. Read the memo on each name — it explains the facts, not a trade order.
- 3
Prioritise higher whale scores
Names with stronger whale scores and broader fund overlap have historically shown more consistent institutional interest. Use score as a filter, not a guarantee.
- 4
Confirm on your own
Check price trend, earnings, valuation, and your own risk tolerance. Whale Signal narrows the field; you make the final call.
What we do not do
- We do not tell you to buy, sell, or hold any security.
- We do not manage money or speak for the funds in your upload set.
- We do not guarantee outcomes — 13F data is delayed, partial, and may reflect rebalancing rather than a directional bet.
- Labels such as “research buy candidate” describe institutional flow patterns for further study only.
