Kim Jiwon, a researcher at KB Securities, commented on the domestic stock market, stating, "Interest in low PBR stocks is expected to continue, driven by expectations for corporate structure improvement pressure and the expansion of shareholder-friendly policies. In addition, the activation of the domestic economy through aggressive fiscal policy is also expected to have an impact."
