NEW YORK (TheStreet) -- With the banks reporting earnings this week, it could be a good time to invest. Looking through TheStreet Quant Ratings, TheStreet's proprietary quant-based stock-rating tool, we picked the eight best large-cap financial services  companies, which are all A+ rated.

The Street Quant Ratings rates every one of these stocks an A+. 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 13, 2015 prices as of 1:43pm.

Year-to-date return: -2.07%

PacWest Bancorp operates as the holding company for Pacific Western Bank that provides commercial banking products and services to individuals, professionals, and small to mid-sized businesses in the United States. It accepts demand, money market, and time deposits.

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

We rate PACWEST BANCORP (PACW) 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, impressive record of earnings per share growth, compelling growth in net income, expanding profit margins and good cash flow from operations. Although no company is perfect, currently we do not see any significant weaknesses which are likely to detract from the generally positive outlook.

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

  • The revenue growth came in higher than the industry average of 1.2%. Since the same quarter one year prior, revenues rose by 11.9%. Growth in the company's revenue appears to have helped boost the earnings per share.
  • PACWEST BANCORP 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 two years. We feel that this trend should continue. During the past fiscal year, PACWEST BANCORP increased its bottom line by earning $1.97 versus $1.08 in the prior year. This year, the market expects an improvement in earnings ($2.95 versus $1.97).
  • The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Commercial Banks industry. The net income increased by 706.1% when compared to the same quarter one year prior, rising from $10.56 million to $85.08 million.
  • The gross profit margin for PACWEST BANCORP is currently very high, coming in at 90.58%. Regardless of PACW's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, PACW's net profit margin of 35.73% significantly outperformed against the industry.
  • Net operating cash flow has significantly increased by 552.48% to $152.51 million when compared to the same quarter last year. Despite an increase in cash flow of 552.48%, PACWEST BANCORP is still growing at a significantly lower rate than the industry average of 3018.12%.

Year-to-date return: 8.56%

R. Berkley Corporation, an insurance holding company, operates as commercial lines writers primarily in the United States. The company operates in three segments: Insurance-Domestic, Insurance-International, and Reinsurance-Global.

TheStreet Ratings team rates BERKLEY (W R) CORP as a Buy with a ratings score of A+. TheStreet Ratings Team has this to say about their recommendation:

We rate BERKLEY (W R) CORP (WRB) 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 good cash flow from operations, solid stock price performance, largely solid financial position with reasonable debt levels by most measures and attractive valuation levels. 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:

  • Net operating cash flow has significantly increased by 143.92% to $271.87 million when compared to the same quarter last year. In addition, BERKLEY (W R) CORP has also vastly surpassed the industry average cash flow growth rate of -45.63%.
  • Looking at where the stock is today compared to one year ago, we find that it is not only higher, but it has also clearly outperformed the rise in the S&P 500 over the same period, despite 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.
  • Despite the weak revenue results, WRB has outperformed against the industry average of 12.5%. Since the same quarter one year prior, revenues slightly dropped by 0.4%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.
  • Despite currently having a low debt-to-equity ratio of 0.52, it is higher than that of the industry average, inferring that management of debt levels may need to be evaluated further.
