Across its top 20 institutional holders, FAST's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 4/100, avg. turnover score 39/100).
FAST ranks #250 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
1471 institutions disclose a position in FAST, but none treat it as a major bet — even Provident Trust Co, its most concentrated holder, allocates just 4.5% of its own portfolio to it.
Assenagon Asset Management S.A. has added to its FAST position for two straight quarters, increasing it by $92.9M to reach $104.0M today.
Fenimore Asset Management Inc has trimmed its FAST position for two straight quarters, cutting it by $15.0M while still holding $154.8M.
FAST is up 1.3% today, and institutions have been net buyers of $7.3B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
FAST posted net income of $1.4B over the trailing twelve months, and currently trades at a P/E of 43.4.

FAST does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.
13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
