Use the decile ranks rather than total returns to gauge consistency year to year. You will rarely find a fund ranked 1 across the row, but most good funds have at least three years out of five of above-average results. Down Market shows performance during the last down market for each category of funds. This atypical bear market indicates primarily the percentage a fund was invested in tech stocks. The higher the volatility, the more potential for gain or loss.
Turnover shows what percentage of a fund the manager replaced last year.
High-turnover funds are costlier because of their hefty trading costs, which aren't reflected in the expense ratios. Assets are for individual share classes. This gives you assurance that, for example, the person who racked up sterling results is still in charge. Minimum investment is what it takes to open an account. For subsequent investments and for IRAs, it's usually lower.
