AI VERDICT

UNEXPLAINEDNO FILINGS · RULE

TANH is up 12.5% on the day on 7.1x its normal volume for this time of day. No filings or headlines were found in SEC EDGAR filings in the last 24 hours, so this is order flow rather than a disclosed catalyst.

WHYNo filings or headlines within 24 hours of the move.

FILINGS · 24H BEFORE THE MOVE

No SEC filings in the 24 hours before this was recorded. A move on an unfiled press release shows nothing here, which is what UNEXPLAINED means.
