NEW YORK (TheStreet) -- With the tech-sector booming and the rest of the markets moving sideways, it could be a good time to invest in what has traditionally been one of the strongest growth sectors. Looking through TheStreet Quant RatingsTheStreet's proprietary quant-based stock-rating tool, we picked the seven best tech companies, which are all A rated.

The Street Quant Ratings rates every one of these stocks an A by measuring the historical price movement of the stock. These stocks were chosen from 4,300 different types of equities we rate.

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.

Check out which stocks made the list. And when you're done, be sure to read about which safe, A+ rated stocks you should buy now. Year-to-date returns are based on October 12, 2015 closing prices.

7. Cadence Design Systems, Inc. (CDNS - Get Report)

Rating: Buy, A
Market Cap: $6.3 billion
Year-to-date return: 14.18%

Cadence Design Systems, Inc.

TheStreet Ratings team rates CADENCE DESIGN SYSTEMS INC as a Buy with a ratings score of A. TheStreet Ratings Team has this to say about their recommendation:

We rate CADENCE DESIGN SYSTEMS INC (CDNS) 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 revenue growth, largely solid financial position with reasonable debt levels by most measures, notable return on equity, reasonable valuation levels and expanding profit margins. Although the company may harbor some minor weaknesses, we feel they are unlikely to have a significant impact on results.

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

  • The revenue growth came in higher than the industry average of 9.8%. Since the same quarter one year prior, revenues slightly increased by 9.8%. Growth in the company's revenue appears to have helped boost the earnings per share.
  • CDNS's debt-to-equity ratio is very low at 0.25 and is currently below that of the industry average, implying that there has been very successful management of debt levels. To add to this, CDNS has a quick ratio of 1.66, which demonstrates the ability of the company to cover short-term liquidity needs.
  • 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 Software industry and the overall market, CADENCE DESIGN SYSTEMS INC's return on equity exceeds that of both the industry average and the S&P 500.
  • The gross profit margin for CADENCE DESIGN SYSTEMS INC is currently very high, coming in at 93.18%. It has increased from the same quarter the previous year.

TheStreet Ratings team rates FIDELITY NATIONAL INFO SVCS as a Buy with a ratings score of A. TheStreet Ratings Team has this to say about their recommendation:

We rate FIDELITY NATIONAL INFO SVCS (FIS) 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, impressive record of earnings per share growth, compelling growth in net income, largely solid financial position with reasonable debt levels by most measures and expanding profit margins. We feel its strengths outweigh the fact that the company shows weak operating cash flow.

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

  • Powered by its strong earnings growth of 37.09% and other important driving factors, this stock has surged by 26.17% over the past year, outperforming the rise in the S&P 500 Index during the same period. Turning to the future, naturally, any stock can fall in a major bear market. However, in almost any other environment, the stock should continue to move higher despite the fact that it has already enjoyed nice gains in the past year.
  • FIDELITY NATIONAL INFO SVCS has improved earnings per share by 37.1% 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 two years. We feel that this trend should continue. During the past fiscal year, FIDELITY NATIONAL INFO SVCS increased its bottom line by earning $2.39 versus $1.66 in the prior year. This year, the market expects an improvement in earnings ($3.30 versus $2.39).
  • The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the IT Services industry. The net income increased by 34.3% when compared to the same quarter one year prior, rising from $178.80 million to $240.20 million.
  • The debt-to-equity ratio is somewhat low, currently at 0.78, and is less than that of the industry average, implying that there has been a relatively successful effort in the management of debt levels. Along with the favorable debt-to-equity ratio, the company maintains an adequate quick ratio of 1.17, which illustrates the ability to avoid short-term cash problems.
  • 42.37% is the gross profit margin for FIDELITY NATIONAL INFO SVCS which we consider to be strong. 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 15.13% trails the industry average.

Fiserv, Inc., together with its subsidiaries, provides financial services technology worldwide.

TheStreet Ratings team rates FISERV INC as a Buy with a ratings score of A. TheStreet Ratings Team has this to say about their recommendation:

We rate FISERV INC (FISV) 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 revenue growth, expanding profit margins, notable return on equity, solid stock price performance and largely solid financial position with reasonable debt levels by most measures. We feel its strengths outweigh the fact that the company has had sub par growth in net income.

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

  • The revenue growth came in higher than the industry average of 21.5%. Since the same quarter one year prior, revenues slightly increased by 3.6%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.
  • The gross profit margin for FISERV INC is rather high; currently it is at 53.31%. 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 9.78% trails the industry average.
  • 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. In comparison to other companies in the IT Services industry and the overall market on the basis of return on equity, FISERV INC has underperformed in comparison with the industry average, but has greatly exceeded that of the S&P 500.
  • Compared to its closing price of one year ago, FISV's share price has jumped by 40.95%, exceeding the performance of the broader market during that same time frame. We feel that the stock's sharp appreciation over the last year has driven it to a price level which is now somewhat expensive compared to the rest of its industry. The other strengths this company shows, however, justify the higher price levels.
  • FISERV INC's earnings per share declined by 18.5% in the most recent quarter compared to the same quarter a year ago. This company has reported somewhat volatile earnings recently. But, we feel it is poised for EPS growth in the coming year. During the past fiscal year, FISERV INC increased its bottom line by earning $2.98 versus $2.45 in the prior year. This year, the market expects an improvement in earnings ($3.82 versus $2.98).
