Stock Trading Signals: Stock Alert - BHI -0.9% but SLB +2.6%, WFT +0.7%- 6/6/12

Oil service stocks (OIH +1.7%) hold up well despite Halliburton's (HAL -2.4%) operational update, which said the price of guar gum "has inflated more rapidly than previously expected due to concerns over the potential for shortages for the commodity later in 2012." It seems unlikely HAL would be the only firm in the sector with tight supplies, Jon Ogg notes. BHI -0.9% but SLB +2.6%, WFT +0.7%
