View all 374 holding institutions

Across its top 20 institutional holders, SIGI's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 4/100, avg. turnover score 37/100).

Notable Holders

SIGI ranks #1652 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

SIGI is a disclosed holding of Cliff Asness (AQR Capital Management), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.

374 institutions disclose a position in SIGI, but none treat it as a major bet — even Tributary Capital Management, LLC, its most concentrated holder, allocates just 1.9% of its own portfolio to it.

American Century Companies Inc has added to its SIGI position for two straight quarters, increasing it by $165.2M to reach $216.2M today.

Fidelity has trimmed its SIGI position for two straight quarters, cutting it by $224.5M while still holding $188.4M.

SIGI is up 0.5% today, and institutions have been net buyers of $1.0B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Company Fundamentals

SIGI posted net income of $497.6M over the trailing twelve months.

  • Profitable — net income of $497.6M over the trailing twelve months
  • Revenue grew 7.0% year over year
  • Net income improved year over year, from $383.7M to $497.6M
  • Generated $1.2B in positive operating cash flow

Smart Money Convergence

SIGI does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 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.
