Separately, TheStreet Ratings Team has a "buy" rating on Chubb with a score of A+. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that the team rates.  

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, solid stock price performance, increase in net income and notable return on equity. TheStreet Ratings believes the strengths outweigh the fact that the company shows weak operating cash flow.
