The stock: Enbridge Energy Partners has advanced 82% in the past year, outperforming major U.S. indices. The stock trades at a price-to-projected-earnings ratio of 17, a premium to oil and gas peers. It offers a 7.7% distribution yield. Distributions are taxed differently than dividends.

The stock: Air Products & Chemicals has increased 50% over the past 12 months, more than the Dow Jones Industrial Average, but less than the S&P 500 Index. The stock trades at a price-to-projected-earnings ratio of 12, a discount to competitors.

1. The model downgraded integrated oil and gas company Statoil ( STO) to "hold."

The numbers: Statoil swung to a fourth-quarter profit of $1.2 billion, or 38 cents a share, from a loss of $802 million, or 26 cents, a year earlier. Revenue soared 156% to $21 billion. The operating margin widened from 14% to 27%. Statoil holds $5.5 billion of cash and $34 billion of debt.
