Investors on CNBC's 'Fast Money Halftime Report' have expressed bullish sentiments on Transocean Ltd (NYSE:RIG), a deepwater drilling company. They believe that the energy sector is set to outperform tech, and that Transocean, with few competitors left in the space, is well-positioned to benefit from rising day rates. The company's shares, which have been in a long-term downtrend, are expected to start producing upside surprises. The iShares U.S. Oil & Gas Exploration & Production ETF (BATS:IEO), representative of the broader oil and gas exploration space, has also been performing well.
