NEW YORK (TheStreet) -- Cable companies earn revenues from cable TV subscriptions and broadband subscriptions. It is broadband services that are the drivers of value for the cable companies as more Americans flock to the Internet sites like Netflix (NFLX) and Amazon (AMZN).

Comcast  (CMCSA - Get Report) and Time Warner (TWC) dominate the broadband subscription market at 39% and 22% market shares, respectively. Comcast has 22 million broadband subscribers and Time Warner has 12.3 million. They've also dominated headlines this week due to the Federal Communication Commission and the Department of Justice nixing their proposed merger.

With that landscape-changing deal off the table, which are the best companies to buy in the space? Well, as it turns out, Comcast and Time Warner are still on the list. Here are the top three, according to TheStreet Ratings,TheStreet's proprietary ratings tool.

TheStreet Ratings projects a stock's total return potential over a 12-month period including both price appreciation and dividends. Based on 32 major data points,TheStreet Ratings uses a quantitative approach to rating over 4,300 stocks to predict return potential for the next year. The model is both objective, using elements such as volatility of past operating revenues, financial strength, and company cash flows, and subjective, including expected equities market returns, future interest rates, implied industry outlook and forecasted company earnings.

Buying an S&P 500 stock that TheStreet Ratings rated a "buy" yielded a 16.56% return in 2014 beating the S&P 500 Total Return Index by 304 basis points. Buying a Russell 2000 stock that TheStreet Ratings rated a "buy" yielded a 9.5% return in 2014, beating the Russell 2000 index, including dividends reinvested, by 460 basis points last year.

Rating: Buy, B
Market Cap: $21.9 billion
Year-to-date return: 13.4%

Sirius XM Holdings Inc., through its subsidiaries, provides satellite radio services in the United States.

"We rate SIRIUS XM HOLDINGS INC (SIRI) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, notable return on equity, impressive record of earnings per share growth, compelling growth in net income and expanding profit margins. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."

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

  • SIRI's revenue growth has slightly outpaced the industry average of 7.3%. Since the same quarter one year prior, revenues slightly increased by 9.1%. This growth in revenue appears to have trickled down to the company's bottom line, improving the earnings per share.
  • SIRIUS XM HOLDINGS INC reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past year. We feel that this trend should continue. During the past fiscal year, SIRIUS XM HOLDINGS INC increased its bottom line by earning $0.09 versus $0.06 in the prior year. This year, the market expects an improvement in earnings ($0.12 versus $0.09).
  • The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Media industry. The net income increased by 119.5% when compared to the same quarter one year prior, rising from $65.20 million to $143.12 million.
  • The company's current return on equity greatly increased when compared to its ROE from the same quarter one year prior. This is a signal of significant strength within the corporation. Compared to other companies in the Media industry and the overall market, SIRIUS XM HOLDINGS INC's return on equity significantly exceeds that of both the industry average and the S&P 500.
  • The gross profit margin for SIRIUS XM HOLDINGS INC is rather high; currently it is at 61.40%. It has increased from the same quarter the previous year. Regardless of the strong results of the gross profit margin, the net profit margin of 13.11% trails the industry average.

2. Time Warner Cable Inc. (TWC)
Rating: Buy, B+
Market Cap: $43.6 billion
Year-to-date return: 2.1%

Time Warner Cable Inc., together with its subsidiaries, provides video, high-speed data, and voice services in the United States. It operates in three segments: Residential Services, Business Services, and Other Operations.

"We rate TIME WARNER CABLE INC (TWC) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, growth in earnings per share, solid stock price performance, good cash flow from operations and expanding profit margins. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."

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

  • Despite its growing revenue, the company underperformed as compared with the industry average of 7.3%. Since the same quarter one year prior, revenues slightly increased by 3.8%. This growth in revenue appears to have trickled down to the company's bottom line, improving the earnings per share.
  • TIME WARNER CABLE INC's earnings per share improvement from the most recent quarter was slightly positive. The company has demonstrated a pattern of positive earnings per share growth over the past two years. We feel that this trend should continue. During the past fiscal year, TIME WARNER CABLE INC increased its bottom line by earning $7.17 versus $6.71 in the prior year. This year, the market expects an improvement in earnings ($8.06 versus $7.17).
  • The stock has risen over the past year as investors have generally rewarded the company for its earnings growth and other positive factors like the ones we have cited in this report. The stock's price rise over the last year has driven it to a level which is somewhat expensive compared to the rest of its industry. We feel, however, that other strengths this company displays justify these higher price levels.
  • Net operating cash flow has increased to $1,810.00 million or 13.19% when compared to the same quarter last year. Despite an increase in cash flow, TIME WARNER CABLE INC's cash flow growth rate is still lower than the industry average growth rate of 47.79%.
  • 36.96% is the gross profit margin for TIME WARNER CABLE INC which we consider to be strong. Despite the high profit margin, it has decreased significantly from the same period last year. Despite the mixed results of the gross profit margin, the net profit margin of 9.56% trails the industry average.

Rating: Buy, A+
Market Cap: $151.6 billion
Year-to-date return: 2.8%

Comcast Corporation operates as a media and technology company worldwide. It operates through Cable Communications, Cable Networks, Broadcast Television, Filmed Entertainment, and Theme Parks segments.

"We rate COMCAST CORP (CMCSA) 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 solid stock price performance, revenue growth, notable return on equity, reasonable valuation levels and good cash flow from operations. We feel these strengths outweigh the fact that the company shows low profit margins."

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

  • The stock has not only risen over the past year, it has done so at a faster pace than the S&P 500, reflecting the earnings growth and other positive factors similar to those we have cited here. 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.
  • Despite its growing revenue, the company underperformed as compared with the industry average of 7.3%. Since the same quarter one year prior, revenues slightly increased by 4.8%. This growth in revenue appears to have trickled down to the company's bottom line, improving the earnings per share.
  • 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 Media industry and the overall market, COMCAST CORP's return on equity exceeds that of both the industry average and the S&P 500.
  • Net operating cash flow has significantly increased by 87.14% to $4,643.00 million when compared to the same quarter last year. The firm also exceeded the industry average cash flow growth rate of 47.79%.
