Across its top 20 institutional holders, BIB's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 8/100, avg. turnover score 34/100).
BIB ranks #8287 out of 37696 tracked stocks by institutional interest, inside the more closely watched half of our coverage.
BIB is a disclosed holding of Ken Griffin (Citadel Advisors LLC), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
21 institutions disclose a position in BIB, but none treat it as a major bet — even Kaizen Financial Strategies, its most concentrated holder, allocates just 0.2% of its own portfolio to it.
Kaizen Financial Strategies has added to its BIB position for two straight quarters, increasing it by $131.0K to reach $613.6K today.
BIB is up 1.9% today, but institutions show net selling of $1.8M this quarter — a divergence between today's price move and the underlying institutional flow.

BIB 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 2026-09-30 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.
