View all 1431 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 37501 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.

BlackRock has added to its TER position for two straight quarters, increasing it by $6.4B to reach $9.4B today.

Allspring Global Investments Holdings, LLC has trimmed its TER position for two straight quarters, cutting it by $670.3M while still holding $15.8M.

TER is down 1.4% today, but institutions show net buying of $39.1B this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

TER posted net income of $1.2B over the trailing twelve months, and currently trades at a P/E of 48.6.

  • 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
  • Generated $674.4M in positive operating cash flow
  • Current ratio of 1.75x — enough short-term assets to cover short-term liabilities
  • Liabilities run 0.50x equity — within a conventional range

Game Theory Scenarios

Bullish— Smart Money Convergence

Institutional Accumulation Dominates Modest Insider Selling

Signal Basis

The latest 13F quarter shows a net value increase of roughly $39.05B, with 817 net-buying institutions versus 592 sellers and 324 new positions against 123 exits; insider activity provides no confirmation — zero buys and six sells totaling ~$4.20M over 90 days, including a $1.70M sale by CEO Gregory Smith on Aug 17 — but at this scale it does not appear sufficient to offset the institutional flow.

Confirmation

A subsequent quarter of continued institutional net accumulation, ideally accompanied by fresh insider purchases or a non-null smart-money convergence flag, would further confirm this read.

Invalidation Risk

Accelerating or clustered insider selling by officers and directors, or a reversal in institutional net flows, would invalidate this verdict.

These scenarios are AI-generated from this stock's institutional holders' SEC EDGAR Form 13F filings and describe historical patterns only. They are not a recommendation to buy or sell this stock; the filings behind this signal are linked below.

See the institutional 13F filings behind this signal

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 2026-06-30 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.
