[BRIEFING.COM] The major averages continue to trade modestly higher at midday, though steadily rising oil prices are beginning to eat into gains across the broader market.
Meanwhile, the Russell 2000 (+1.5%) and S&P Mid Cap 400 (+1.1%) are outperforming on both a daily and week-to-date basis. Both indices hold decent gains for the week, while the major averages all hold losses of 1.3% or wider.
