A leading stock experienced a sharp reversal. On the morning of April 1, Laplace surged in a straight line and hit the 20% daily limit-up. However, following the release of a clarification announcement, the stock quickly reversed gains in the afternoon and plummeted sharply.

Market news indicated that media reports suggested Laplace recently won the second phase of a solar project from Tesla Motors, with the order size reportedly close to 10 billion yuan. In response to this "major positive news," Laplace stated they were "not very clear." Subsequently, at midday on April 1, Laplace issued a clarification announcement regarding the market rumors.

Laplace stated that after verification, as of now, the company has not obtained any related orders. The company confirmed there is no material information that should be disclosed but has not been. If any future developments meet disclosure standards, the company will strictly comply with relevant laws and regulations to fulfill information disclosure obligations.

Additionally, Laplace mentioned that the company's fundamentals have not undergone significant changes. The company noted that its stock price has risen substantially recently, indicating risks of overheated market sentiment and irrational speculation. They cautioned that the stock price may experience a rapid short-term decline, and investors engaging in trading could face significant risks. The company advised investors to invest rationally and be mindful of investment risks.

On the morning of April 1, besides Laplace, several other solar-related concept stocks also strengthened. Companies such as Liancheng CNC, Mayer Holdings, Jiejia Weichuang, and Jinko Solar all experienced significant surges around the same time.
