This is a Beijing company, not one of the many provincial companies (think Yunnan Province) that sought US markets just to steal "capital".
Although I don't know why today was a catalyst for such a surge, I can tell you that in 5 years of conversations with the company, including the departed CFO (got an internal audit job with an Oracle subsidiary, I believe), the Secretary, and the CEO (through translator); I highly doubt that this company is fraudulent. They have been trying to convince foreign investors of this with very little success, but they continue to try and be as transparent as they can be and are willing to answer just about any question, no matter how invasive and direct.
Lastly, E-Future has rather detailed financials. If they were going to spend all that time cooking the books, why would they go beyond the baseline in terms of financial transparency and line by line cash flow accounts in every quarterly/annual statement. They would also post a profit on top of growing revenues, but they haven't, because they are growing like a normal company in a cutthroat competitive environment. E-Future's customers and partnerships are real. Don't believe me? Call Kronos.
