More often than not the technology sector reports above par earnings than other sectors fueled by the demand for technology and innovation. However, technology stocks are considered to be more volatile than other sector stocks in the short run. In order to minimize this short-term volatility almost all tech funds adopt a growth management style with focus on strong fundamentals and a relatively broader investment horizon. Investors having an above par appetite for risk and a fairly longer investment horizon should park their savings in these funds.
