View all 1044 holding institutions

Across its top 20 institutional holders, LH's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 4/100, avg. turnover score 31/100).

Notable Holders

LH ranks #447 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

LH is a top-conviction position for Navera Investment Management Ltd. — at 5.9% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in LH belongs to BlackRock, Inc., but the position matters far more to Navera Investment Management Ltd., who has 5.9% 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.

Boston Partners has added to its LH position for two straight quarters, increasing it by $373.9M to reach $854.2M today.

Wellington Management Group LLP has trimmed its LH position for two straight quarters, cutting it by $252.9M while still holding $239.6M.

LH is down 0.2% today, but institutions show net buying of $7.3B this quarter — a divergence between today's price move and the underlying institutional flow.

  • Profitable — net income of $1.0B over the trailing twelve months
  • Revenue grew 6.4% year over year
  • Net income improved year over year, from $763.4M to $1.0B
  • Generated $1.6B in positive operating cash flow

Game Theory Scenarios

Neutral— Wait & Watch

Institutions accumulate $7.3B while insiders uniformly sell

Signal Basis

13F filings show a net value increase of $7.33B with 102 new positions versus 74 exits, yet buyer and seller counts are nearly even at 462 vs 465. Meanwhile, insiders executed zero buys and 5 sells totaling ~$3.17M over the past 30 days, with CEO Adam Schechter accounting for ~$1.5M of the selling — a clear divergence between institutional accumulation and insider distribution.

Confirmation

A shift in insider behavior toward buying, or a widening of the institutional buyer count margin, would confirm a directional bias.

Invalidation Risk

Continued insider selling alongside a reversal in institutional net flows would tilt the signal bearish.

This analysis is machine-generated from institutional holders' Form 13F data on SEC EDGAR and limited to historical trends. Not financial advice — see the source filings below.

Smart Money Convergence

LH 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.
