Are Solidion Technology insiders buying or selling STI?

In the 180 days to 2026-10-28, Solidion Technology insiders were net sellers, a net $15.2M: $694.4K of purchases and $15.9M of sales reported on Form 4, by 4 buyers and 2 sellers.

Read the full summary

In the 180 days to 2026-10-28, Solidion Technology insiders were net sellers of STI, a net $15.2M across purchases and sales reported on Form 4 by 4 buyers and 2 sellers. Most of that figure, $15.3M, came from a holder of 10% or more rather than an officer or director. Sales outweighed purchases more than tenfold by value. 3 different insiders reported purchases within the last 90 days, a cluster buy, which is rarer than a single purchase. None of the 4 insider sales was flagged as made under a Rule 10b5-1 plan. Each figure is counted from SEC and House filings as of 2026-10-28, dated the day the filing was made public.
