VOOV is trading at $238.22, up 5.92% from the September 22 close of $225.86 in pre-market; the gain may reflect a stale or erroneous quote, as broader market trading does not support it. - S&P 500 futures are modestly higher, while Nasdaq and Dow futures are slightly lower. - Falling oil prices and U.S.-Iran diplomatic progress supported Treasury futures and European equities overnight, but do not explain the nearly 6% value-ETF gain.
