Yes, it is. On an absolute basis, the Facebook IPO resulted in the lowest 5-day return of any US IPO in the past century. The qualifier "largest" was used only because FB lost more capital in 5 days than the total market caps of the companies involved in the worst IPOs, so it is not the worst IPO on a relative basis. Even then, Facebook still ranks among the worst IPOs in the past decade.
