NEW YORK (TheStreet) -- Shares of oil refinery company Valero Energy (VLO - Get Report) were falling 2.9% to $61.52 Friday as oil prices declined after five straight days of gains.

WTI crude oil for May delivery was down 5.2% to $48.74 Friday afternoon and Brent oil for May delivery was down 4.7% to $56.40 a barrel.

Oil prices were falling after bombing in Yemen continued overnight, but fears that the conflict would disrupt oil exports lessened, according to Reuters. Oil prices increased Thursday after airstrikes in Yemen sparked fears that it could disrupt world oil supplies.

Goldman Sachs said that the bombing will likely have little effect on oil supplies as Yemen was a small crude exporter and tankers can avoid passing the country on their way to other ports, according to Reuters.

TheStreet Ratings team rates VALERO ENERGY CORP as a Buy with a ratings score of A-. TheStreet Ratings Team has this to say about their recommendation:

"We rate VALERO ENERGY CORP (VLO) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its attractive valuation levels, increase in stock price during the past year, largely solid financial position with reasonable debt levels by most measures and notable return on equity. We feel these strengths outweigh the fact that the company shows weak operating cash flow."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • The current debt-to-equity ratio, 0.31, is low and is below the industry average, implying that there has been successful management of debt levels. Although the company had a strong debt-to-equity ratio, its quick ratio of 0.97 is somewhat weak and could be cause for future problems.
  • The return on equity has improved slightly when compared to the same quarter one year prior. This can be construed as a modest strength in the organization. Compared to other companies in the Oil, Gas & Consumable Fuels industry and the overall market on the basis of return on equity, VALERO ENERGY CORP has underperformed in comparison with the industry average, but has exceeded that of the S&P 500.
  • Compared to where it was a year ago today, the stock is now trading at a higher level, regardless of the company's weak earnings results. Turning our attention to the future direction of the stock, it goes without saying that even the best stocks can fall in an overall down market. However, in any other environment, this stock still has good upside potential despite the fact that it has already risen in the past year.
  • Regardless of the drop in revenue, the company managed to outperform against the industry average of 19.6%. Since the same quarter one year prior, revenues fell by 19.1%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.
