Dong’an Power says flying-car business has no revenue; shares hit limit-up 3 days

The gap between a concept label and zero revenue is the whole story here: the market is pricing a narrative the company itself says has no financial substance yet, and the risk notice is an explicit attempt to cool that gap. This matters most for momentum-driven traders in concept names, where a limit-up streak can outrun disclosure. The open question is whether the exchange or regulators step in given the company's own admission that fundamentals haven't changed — and whether similar concept tags elsewhere draw comparable risk notices.
