Whale Following Strategies in 2025: The Final Score

Whale following — copying large institutional options flows or using 13F filing data to mirror hedge fund positions — attracted significant retail interest through 2025. At year-end, the honest assessment is: mixed results, persistent structural problems, and a growing gap between the compelling narrative and the practical returns.
What Is Whale Following?
Whale following generally refers to two related but distinct approaches:
1. Options flow following: Monitoring large unusual options activity — big block purchases of calls or puts — and trading in the same direction, assuming the buyer has informed insight.
2. 13F following: Using SEC-required quarterly holdings filings from large institutional investors to replicate their stock portfolios. The SEC requires institutional managers with over $100 million in assets to disclose equity holdings quarterly.
Both approaches start from the same premise: large sophisticated players have an edge, and following them captures some of that edge. 2025 tested that premise in real market conditions.
The 13F Problem: Data That Is Always 90 Days Old
13F filings are due within 45 days of each quarter's end, meaning the most current possible data reflects positions from up to 135 days ago. A position disclosed in February represents holdings as of December 31 — before two months of market movement.
This delay is the structural problem that does not go away regardless of how carefully you read filings. What 13F filings are and why their limitations matter covers this in detail.
In 2025, several high-profile 13F-disclosed positions appeared strong at the time of disclosure but had already been significantly altered or exited by the time retail followers acted on the data. Institutional managers are under no obligation to hold positions disclosed in a 13F, and many actively manage around the disclosure cycle.
Did Unusual Options Flow Predict Market Moves in 2025?
Unusual options activity — large block purchases at strikes well away from the current price — attracted enormous retail attention in 2025, fueled by social media commentary and flow analysis services. The assumption underlying this attention is that large buyers have information that small traders do not.
The SEC's institutional investor disclosure framework exists precisely because information asymmetry in markets is a real phenomenon. But the practical question is whether the unusual flow signal translates to actionable retail trades.
The evidence from 2025 is mixed at best:
- Some large block purchases preceded significant moves in the intended direction
- Many others were hedging activity, portfolio insurance purchases, or institutional risk management that had nothing to do with directional views
- The noise-to-signal ratio in publicly available options flow data remained high
Whether following unusual options activity actually works covers the research on this question directly.
The Alpha Decay Problem
Even when institutional flows or 13F data contained genuine informational signal, the act of publishing that signal publicly accelerated its decay. In 2025, the most followed options flow accounts and services attracted enough capital that mimicking their signals moved prices, reducing the edge available to later followers.
This is a classic problem with any publicized edge: it works until enough people know about it.
What Did Work in 2025?
Whale following as a retail income strategy produced inconsistent results in 2025 — some followers had productive periods, others gave back gains trying to replicate institutional moves they did not fully understand.
The more consistent approach for income-focused traders was structural: strategies that collect premium systematically rather than attempting to time directional moves based on institutional signals.
Tradematic is an automated iron condor trading platform. Importantly, it uses institutional data — gamma levels, dealer hedging flows, hedge wall positioning — not to copy institutional trades, but to identify where market makers are concentrated and thus where price stability is most likely. This is a fundamentally different use of institutional information: understanding market structure rather than mimicking positions.
The distinction matters. Smart money vs consistent income as strategies covers why these approaches have different risk profiles.
The Final Score for Whale Following in 2025
Inconsistent. Structurally limited by disclosure delays and noise in publicly available flow data. High narrative appeal but lower practical alpha than the compelling stories suggested.
The traders who finished 2025 ahead were not primarily the ones who best identified whale activity — they were the ones who ran disciplined, systematic strategies and managed risk consistently.

Frequently Asked Questions
Did any whale following services generate strong returns in 2025? Some specific calls from flow-following services worked well and attracted significant attention. But consistent, systematic outperformance across all their signals was not broadly evident. Cherry-picking the wins without accounting for the misses produces misleading performance pictures.
How is Tradematic's use of institutional data different from whale following? Tradematic uses gamma levels and dealer hedging flows to understand where market makers are positioned structurally — identifying price stability zones for iron condor strikes. It does not copy institutional trades or follow options flow. The data informs strike selection, not directional bets.
Are 13F filings still useful at all for retail investors? They provide a general picture of institutional preferences over time, useful for long-term thematic research. They are not useful for tactical trading decisions due to the 45–135 day delay between position and disclosure.
Why does publicizing options flow signals reduce their effectiveness? When many traders act on the same signal simultaneously, they collectively move the price toward the target. Later followers get worse fills, and the original expected move is compressed by the crowd's collective action.
Trading involves risk and losses can occur. Past performance does not guarantee future results. Options trading is not suitable for all investors. Only allocate capital you are comfortable risking.
