JAVLIN Invest’s rank feature provides your portfolio a letter grade based on its daily return, volatility, CVaR, and Sharpe ratio (see Glossary for definitions). To calculate these, we compare your portfolio to the S&P 500, an index of 500 large companies based in the U.S. As our benchmark, the S&P 500’s performance always earns a C rank. If your portfolio earns a B or higher, it’s performing better than the S&P 500.
