TECL provides 3x levered exposure to the S&P Technology Select Sector Index, reset daily. Like all levered funds, it tends to underperform in volatile markets if held for longer than its reset period, and is only suitable for short-term trading positions. The underlying index (tracked in unlevered form by SSgA's XLK) consists of all tech companies in the S&P 500. This broad definition of the tech sector means TECL contains names traditionally thought of in technology in addition to those in diversified telecommunications services, communications equipment, semiconductors, and office electronics. However, the portfolio is concentrated in just a few names. It is important to clearly understand the risks in using such leverage. In addition, this product should only be utilized by those who actively manage their investments.
