View all 1439 holding institutions

Across its top 20 institutional holders, TER's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 7/100, avg. turnover score 38/100).

Notable Holders

TER ranks #261 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

TER is a top-conviction position for Anther Capital Ltd — at 8.3% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in TER belongs to BlackRock, Inc., but the position matters far more to Anther Capital Ltd, who has 8.3% 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.

Wealth Enhancement Advisory Services, LLC has added to its TER position for two straight quarters, increasing it by $174.0M to reach $188.8M today.

Essential Partners LLC has trimmed its TER position for two straight quarters, cutting it by $2.2M while still holding $714.4K.

TER is down 5.3% today, but institutions show net buying of $39.1B this quarter — a divergence between today's price move and the underlying institutional flow.

  • Profitable — net income of $1.2B over the trailing twelve months
  • Revenue grew 53.6% year over year
  • Net income improved year over year, from $577.1M to $1.2B

Smart Money Convergence

TER 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.
