Vanguard Information Technology Index Fund Admiral Shares 

This affordably priced index fund offers targeted access to the American technology sector. It primarily focuses on companies supporting the electronics and computer industries, or those developing products rooted in advanced scientific applications. The principal risk of this fund lies in its concentrated nature, as it invests exclusively in information technology stocks. Investors should, therefore, anticipate significant price volatility. It is best considered as a small, supplementary component within an already well-diversified overall investment portfolio.
