$VXX STCMVF settled @ 15.767 (-1.2%). The short-term constant-maturity VIX futures (STCMVF) is a weighted average of the current front- and back-month VIX futures contracts. It serves as a benchmark for the short-term volatility ETPs (e.g., VXX, VIXY, SVXY, UVXY, TVIX) and is comparable to the S&P 500 30-day volatility index (VIX). STCMVF is an ideal but inaccurate reflection of portfolios held by the volatility ETPs, and STCMVF excludes roll loss due to daily resetting. Another benchmark that includes roll loss is the ticker SPVIXST.
