Notable Holders

CBT ranks #1569 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

The largest dollar stake in CBT belongs to BlackRock, Inc., but the position matters far more to Lightrock Netherlands B.V., who has 6.4% 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.

David Shaw has trimmed its CBT position for two straight quarters, cutting it by $17.4M while still holding $1.9M.

Smart Money Convergence

CBT 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.

On August 21, 2026, specialty chemicals maker Cabot Corporation completed the sale of $350 million in senior notes paying 4.95% annual interest and maturing in 2029. Per the filing, most of the proceeds will go toward redeeming its existing $250 million of 3.40% notes coming due in September 2026 — essentially swapping older, cheaper debt for new debt at today's higher rates — with what's left earmarked for working capital and other general corporate needs.
