Across its top 20 institutional holders, CEG's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 11/100, avg. turnover score 38/100).

Notable Holders

CEG ranks #161 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

CEG is a top-conviction position for ECP ControlCo, LLC — at 76.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in CEG belongs to BlackRock, Inc., but the position matters far more to ECP ControlCo, LLC, who has 76.5% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Vontobel Holding Ltd. has added to its CEG position for two straight quarters, increasing it by $14.2M to reach $19.1M today.

Segra Capital Management, LLC has trimmed its CEG position for two straight quarters, cutting it by $25.9M while still holding $44.7M.

CEG is down 1.3% today, but institutions show net buying of $24.4B this quarter — a divergence between today's price move and the underlying institutional flow.

CEG posted net income of $3.5B over the trailing twelve months, and currently trades at a P/E of 24.6.

  • Profitable — net income of $3.5B over the trailing twelve months
  • Revenue grew 20.5% year over year
  • Net income improved year over year, from $3.0B to $3.5B
  • Generated $4.2B in positive operating cash flow

Smart Money Convergence

CEG does not currently show a 13F-and-insider convergence signal — its insider confidence score is 43/100, 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.
