How FilingFrog Data Gets Used

Real-world examples you can model your own citations after. Each data point is directly queryable in the platform.

All examples reflect Q4 2025 13F filings processed from SEC EDGAR. Figures cite the 45-day reporting window closing mid-February 2026.

CRCL

Circle Internet Group

IPO Coverage

The story angle: Circle Internet's 2025 IPO was one of the most anticipated in the crypto-adjacent space — but the institutional picture was more nuanced than the headlines suggested. Q4 13F data reveals a classic split between fast-money sellers and long-only accumulators entering on the dip.

Key question answered: Was institutional conviction building or declining heading into the IPO lock-up expiration?

"Despite 88 institutional managers exiting their Circle Internet Group (CRCL) position in Q4, 212 managers added new or expanded exposure during the same period — a 2.4-to-1 buyer-to-seller ratio that suggests accumulation, not distribution, according to FilingFrog analysis of SEC 13F filings." — FilingFrog, Q4 2025 13F Data

New/Expanded positions: 212 Exits: 88 Net buyer ratio: 2.4× Period: Q4 2025

Micron Technology

Sector Rotation

The story angle: As AI infrastructure spending accelerated in 2025, memory chip demand became a proxy trade for the AI buildout. Micron's institutional ownership data captures broad-based re-rating — not just the large funds moving in, but a notable surge among smaller managers who typically lag the mega-cap consensus.

Key question answered: Was the Micron rally driven by a narrow group of large institutions, or was there genuine breadth?

"Institutional conviction in Micron Technology (MU) widened substantially in Q4 2025, with the number of 13F managers reporting exposure rising 21% — from 2,037 to 2,462. Notably, managers with under $1B in assets saw an even sharper 31% increase in ownership, suggesting the AI memory trade reached well beyond the largest fund complexes, per FilingFrog data." — FilingFrog, Q4 2025 13F Data

Holders Q3: 2,037 Holders Q4: 2,462 Overall growth: +21% Sub-$1B managers: +31%

FISV

Fiserv

Post-Earnings Fallout

The story angle: Fiserv's November 2025 earnings miss triggered a sharp selloff — but 13F data quantifies just how decisive the institutional response was. Beyond stock price, the ownership data reveals whether large funds cut and ran or held through the volatility.

Key question answered: After a high-profile earnings miss, did institutional holders stay patient or vote with their feet?

"Fiserv (FISV) ranked as the most widely exited large-cap position among institutional 13F filers in Q4 2025 — 21% of all managers with prior exposure fully exited their position following the November earnings disappointment, according to FilingFrog's analysis of SEC filings." — FilingFrog, Q4 2025 13F Data

Exit rate: 21% of holders Rank: #1 most exited Trigger: Nov 2025 earnings Period: Q4 2025

Story Ideas

What Can You Write With This Data?

13F data opens angles that price charts alone can't tell.

Conviction Behind the Rally

Is a stock's run driven by broad institutional buying, or just a few large funds? Ownership breadth tells the story price can't.

Who's Still Holding the Bag

After a headline-grabbing crash, how many institutions are still long? Track the exit rate and who's staying patient vs. cutting losses.

The Small Fund Signal

Smaller managers (under $1B AUM) often move first. Isolate their activity to surface positioning shifts before the consensus catches up.

IPO & Lock-Up Expiration Stories

Who accumulated at IPO, who flipped quickly, and how did the holder count evolve through the lock-up expiration window?

AI / Sector Rotation Tracking

Map institutional flows into and out of sectors quarter-by-quarter. Which themes are gathering momentum vs. losing support?

Portfolio Overlap Analysis

Which positions do Berkshire and Tiger Global share? What does "consensus long" look like across the biggest funds this quarter?
