Across its top 20 institutional holders, STE's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 32/100).
STE ranks #616 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
841 institutions disclose a position in STE, but none treat it as a major bet — even Generation Investment Management LLP, its most concentrated holder, allocates just 4.7% of its own portfolio to it.
Assenagon Asset Management S.A. has added to its STE position for two straight quarters, increasing it by $11.3M to reach $22.1M today.
Sustainable Growth Advisers, LP has trimmed its STE position for two straight quarters, cutting it by $71.1M while still holding $49.9M.
STE is up 2.1% today, and institutions have been net buyers of $5.8B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
STE posted net income of $805.1M over the trailing twelve months.

STE 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.
