California Investment Trust offers an S&P Small Cap Index fund to its shareholders. The goal of this fund is to replicate the performance of small-sized US Companies as measured by the S&P SmallCap 600 Stock Index. Over long periods of time, small cap stocks have generally outperformed other segments of the market. However, they also have shown more volatility in share price than the stocks of larger sized companies. Many investors believe that small cap stocks are the best choice for long term investment, though there can be no assurance that this trend will continue.
