Across its top 20 institutional holders, SBLK's holder base skews toward low-concentration, high-turnover investors on average (avg. concentration score 10/100, avg. turnover score 51/100).
SBLK ranks #2943 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
SBLK 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.
SBLK is a top-conviction position for Fearnley Asset Management As — at 9.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in SBLK belongs to Two Sigma Investments, LP, but the position matters far more to Fearnley Asset Management As, who has 9.0% 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.
Two Sigma Investments, LP has added to its SBLK position for two straight quarters, increasing it by $77.9M to reach $88.8M today.
Ameriprise Financial Inc has trimmed its SBLK position for two straight quarters, cutting it by $40.4M while still holding $893.9K.
SBLK is down 4.9% today, but institutions show net buying of $130.1M this quarter — a divergence between today's price move and the underlying institutional flow.
SBLK closed its latest fiscal year with net income of $84.2M, and currently trades at a P/E of 40.6.

SBLK does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
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.
