Shares of Keisei Electric Railway Co. and Keikyu Corp. experienced significant increases on Monday due to reports of a fund linked to activist investor Yoshiaki Murakami acquiring substantial stakes in the companies.
An unidentified source revealed that the Murakami-associated fund has secured nearly a 5% stake in Keikyu and holds less than 1% of Keisei shares. This news has generated investor interest, leading to notable highs in the market for both companies.
Keisei's stock saw a remarkable rise of over 18%, its largest intraday increase since October 2008, while Keikyu's shares climbed more than 16%, the highest jump since 1987.
