NEW YORK (TheStreet) -- Shares of Transocean (RIG - Get Report) are decreasing 1.82% to $10.80 late Friday afternoon as oil prices decline.

WTI is down 0.63% to $33.06 per barrel, while Brent crude is retreating 0.77% to $33.49 per barrel this afternoon, according to the CNBC.com index.

Oil prices dropped for a fifth day today and are set to hit a weekly decline of 10% on a continuing global oversupply and a bearish demand outlook, Reuters reports.

Goldman Sachs added to the negative view on Friday with notes from an energy conference in Miami this week that concluded oil producers were not ready to reduce enough production at existing prices, Reuters added.

"We believe we need to see sustained low oil prices in late 2015/1Q 2016 so producers will move budgets down to reflect $40/bbl oil for 2016," the firm said in a note cited by Reuters. "Instead, producers spoke largely of their agility to spend within cash flow and, as described below, ramp up when needed."

Transocean is Switzerland-based provider of offshore contract drilling services for oil and gas wells.

Separately, recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author. TheStreet Ratings has this to say about the recommendation:

We rate TRANSOCEAN LTD as a Sell with a ratings score of D+. This is driven by some concerns, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its weak operating cash flow and generally disappointing historical performance in the stock itself.

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

  • Net operating cash flow has decreased to $648.00 million or 26.53% when compared to the same quarter last year. In conjunction, when comparing current results to the industry average, TRANSOCEAN LTD has marginally lower results.
  • RIG's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 34.32%, which is also worse that the performance of the S&P 500 Index. Investors have so far failed to pay much attention to the earnings improvements the company has managed to achieve over the last quarter. Naturally, the overall market trend is bound to be a significant factor. However, in one sense, the stock's sharp decline last year is a positive for future investors, making it cheaper (in proportion to its earnings over the past year) than most other stocks in its industry. But due to other concerns, we feel the stock is still not a good buy right now.
  • 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 Energy Equipment & Services industry and the overall market on the basis of return on equity, TRANSOCEAN LTD underperformed against that of the industry average and is significantly less than that of the S&P 500.
  • Regardless of the drop in revenue, the company managed to outperform against the industry average of 31.0%. Since the same quarter one year prior, revenues fell by 29.2%. The declining revenue has not hurt the company's bottom line, with increasing earnings per share.
  • RIG's debt-to-equity ratio of 0.64 is somewhat low overall, but it is high when compared to the industry average, implying that the management of the debt levels should be evaluated further. Despite the fact that RIG's debt-to-equity ratio is mixed in its results, the company's quick ratio of 2.03 is high and demonstrates strong liquidity.
