ASTERIA shares plunge on post-SpaceX IPO 'buy the rumor, sell the fact' sentiment

Mon Jun 15, 2026 3:18 pm JST Catalyst

Asteria <3853> plunged sharply on Monday, June 15, as a classic "sell-the-news" reaction gripped investors following the historic initial public offering (IPO) of U.S. aerospace giant SpaceX on the Nasdaq.

While Asteria operates primarily as an enterprise systems development firm specializing in data integration tools, the stock is widely tracked due to its high-profile investment stake in SpaceX. Shares had embarked on a strong upward trajectory starting mid-May, fueled by mounting market speculation ahead of the aerospace company's highly anticipated public debut. However, following that initial peak, the stock reversed course as speculative momentum began to unwind. The official completion of SpaceX's Nasdaq listing on Friday, June 12, accelerated the downward pressure, as market participants viewed the milestone as a fully priced-in event with its catalyst exhausted.

Prior to the market open on Monday, Asteria issued a timely disclosure regarding the financial implications of the SpaceX listing, stating that the precise impact on its consolidated earnings?specifically concerning unrealized valuation gains or losses on investment securities?is "currently under review." Asteria has maintained its position in SpaceX through its investment subsidiary since the fourth quarter of the fiscal year ended March 2022. Separately, on Tuesday, June 9, the company announced it would recognize a gain of approximately 400.00 million yen stemming from a partial divestment of its SpaceX holdings.
