Factorial Energy's sharp reversal after its initial post-SPAC surge illustrates a well-documented pattern in SPAC-listed stocks where debut-day gains are quickly erased by profit-taking from SPAC investors who purchased shares at pre-merger trust values. SPAC structures create a built-in seller cohort — investors who have the right to redeem shares at trust value — and those who choose to hold through the merger often sell into the initial price spike. Additionally, SPAC-listed companies are often less seasoned in investor relations and have fewer institutional anchors compared to traditionally IPO'd companies, leading to wider price swings. For long-term investors interested in solid-state battery technology, FAC's post-debut sell-off may represent a more rational entry point than the debut-day peak.
