ReTo Eco-Solutions Inc. shares rose 676.27% to close at $2.80 during Tuesday’s regular session, then gained another 54.69% to $4.33 in after-hours trading. Volume reached 232.79 million shares, about 258 times the company’s typical daily volume of 901,640 shares, without an apparent earnings report, contract or operational update explaining the move. The rally followed the Securities and Exchange Commission’s designation of ReTo’s registration statement as abandoned after more than nine months without activity. In August, the company entered a financing arrangement allowing up to $36 million in discounted, prepaid share purchases from an institutional investor, raising dilution concerns. ReTo also completed a 4-for-1 reverse stock split in May, reducing outstanding Class A shares from approximately 13.08 million to 3.27 million to help maintain Nasdaq compliance. The company has a market capitalization of $103.38 million, approximately 35.85 million shares outstanding, a 52-week high of $28.40 and a low of $0.35. Its Relative Strength Index was 68.12, while the stock remained down 89.31% over the past year and traded at about 8.7% of its 52-week price range. Institutional positioning was negative in the latest reporting quarter: no investors increased their stakes, three reduced them, XTX Topco exited its 3,366-share position, UBS Group cut its holding by 30% and SBI Securities reduced its stake by 81.8%.
