*Here's the methodology from TipRanks:

TipRanks looks at a variety of benchmarks, including the traditional % average over the S&P 500 and performance success rate. But, we go far beyond this information in our ranking over the analysts.

When it comes to evaluating adviser performance, we not only measure how much an analyst outperforms a specific benchmark, but also how consistent they are in doing so.

As such, TipRanks uses the statistical Z-test to determine the statistical viability / consistency of financial advisers stock recommendations against a benchmark.

Z-test enables answering tough questions when it comes to comparing financial advisor performance, for example:

· Which adviser has a better success rate, one that gave 10 recommendations out of which 7 outperformed the benchmark (70%) or one that gave 100 recommendations out of which 68 outperformed the benchmark (68%)? While 70% is greater than 68%, achieving a 68% success rate over 100 recommendations is “statistically harder” than achieving 70% over 10.

· Which adviser has a higher excess return over the benchmark, one that gave 10 recommendations and outperformed the benchmark by 3.2% or one that gave 100 recommendations and outperformed the benchmark by ‘only’ 3%?



To measure the adviser performance against the benchmark, TipRanks calculates the Z-score the recommendation set given by each adviser and can thus compare an adviser with 10 recommendations to an adviser that gave 100 recommendations.
