A year ago, few of the top-performing sector funds of the past 15 years were able to keep up with the S&P 500, which went on to a 32.39% gain for the full year. But this year most of the long-term leaders are back on top, led by gold funds. Tocqueville Gold Fund has rallied 32.46% so far this year vs. 6.54% for the broad stock market as tracked by S&P 500.
