The Overall Ranking is a score from 1 star (very bad) to 5 stars (excellent) generated based on the Company Reviews of current and former employees at this company, taking everything into account.
The number you see in the middle of the donut pie chart is the simple average of these scores. If you hover over the various sections of the donut, you will see the % breakdown of each score given.
The percentile score in the title is calculated across the entire Company Database and uses an adjusted score based on Bayesian Estimates (to account for companies that have few reviews). Simply put, as a company gets more reviews, the confidence of a "true score" increases so it is pulled closer to its simple average and away from the average of the entire dataset.

Joe DiMenna joined Zweig Cos. in 1977 while he was studying at Fairfield University. DiMenna was a keen reader of "The Zweig Forecast", and he decided to send a letter to Martin Zweig about potential investment suggestions. After reading his letter, Zweig decided to hire DiMenna as a summer intern. Through the years, their partnership flourished and they formed Zweig-DiMenna International Limited in 1984.
The duo was successful in producing strong returns for their investors over the years. Zweig-DiMenna Partners was up almost 90% for the last 5 years as of early 2011. However, as mentioned in a previous article, their fund did not perform up to investor expectations, losing around 20% since August 2008.
