Earnings per share improved year over year as well, while also eclipsing the consensus. ENSCO's average day rate for its jackup rig fleet increased by 29% and utilization of its jackup fleet advanced to 93%. Looking toward the full year, ENSCO believes higher average day rates and an increase in rig operating days with the addition of ENSCO 108 should contribute to 'significant' earnings improvement in 2007. The company remains one of the All Stars' favorite names in its industry.

Hilton Hotels Corporation (NYSE: HLT) will report its first-quarter results next week. The hotels giant, which remains a member of the All Star Analyst Portfolio, is coming off of a strong fourth-quarter performance. Earnings per share advanced on a year-over-year basis with revenue that improved to $2.23 billion.

Analysts currently expect earnings per share of 18 cents for the first quarter.

Helix Energy Solutions (NYSE: HLX) is an international offshore energy company that provides development solutions and other key life of field services to the open energy market and its own oil and gas business unit.
