SEM ranks #2553 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

SEM is a disclosed holding of Two Sigma (Two Sigma Investments), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.

SEM is a top-conviction position for Decagon Asset Management LLP — at 8.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in SEM belongs to BlackRock, Inc., but the position matters far more to Decagon Asset Management LLP, who has 8.5% 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.
