Today's Volume: 167,000 Average Volume: 180,586 Volume % Change: 200% >>7 Undervalued Oil and Gas Stocks Ripe for Gains Shares of SXL are moving higher today after Robert W. Baird initiated coverage on this stock with an outperform rating and a $53 price target. From a technical perspective, SXL is spiking higher here with decent volume, and it's started to break out above some near-term overhead resistance $44.99. Traders should now look for long-biased trades in SXL as long as it's trending above today's low of $44.54 with strong upside volume flows. I would consider any upside volume day that registers near or above 180,586 shares as bullish. If SXL can maintain that trend, then this stock has a great chance of hitting $50 in the near future. That said, SXL has entered overbought territory since its current relative strength index is 82.18. If SXL fails to hold this breakout, then I would avoid it or look for short-biased trades if it moves back below some major near-term support at $43.27 to $42.
