Why is Tantech Holdings Ltd. (TANH) stock moving?
TANH has had a second spike in three weeks, and no company news explains it. The stock closed at $11.67 on Nov 6. It then rose to $19.34 on Nov 9 on about 1.11M shares, against sub-75K shares a day earlier in the month. On Nov 10 it ranged from about $15 to nearly $40 and closed at $30.56 on about 1.13M shares. It was at $36.30 in early trade on Nov 11. Coverage found no company release or filing behind the move. The Oct 22 spike followed the same pattern. It faded from a $24.83 close to $17.71 on Oct 23 and $13.01 by Oct 26, on 616K shares on Oct 23. The market cap is only about $19-25M, with about 668K shares outstanding after the 1-for-50 reverse split. The float is tiny, and the stock is very sensitive to order flow. Fundamentals are weak: the stock is down about 80% over 12 months, FY net loss is about $31M, and the chairman resigned in October. Offsetting that, the balance sheet shows a current ratio of about 6.6 and trades far below book value. The price is now almost 3x the Nov 6 close. The last spike reversed sharply, so another pullback looks likely. Momentum is strong right now, though, and a squeeze could extend it.
