The market prices of technology and technology-related stocks tend to exhibit a greater degree of market risk and price volatility than other types of investments. These stocks may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. These stocks also may be affected adversely by changes in technology, consumer and business purchasing patterns, government regulation and/or obsolete products or services. Technology and technology-related companies are often smaller and less experienced companies and may be subject to greater risks than larger companies, such as limited product lines, markets and financial and managerial resources. These risks may be heightened for technology companies in foreign markets. The Fund’s use of derivatives introduces risks possibly greater than the risks associated with investing directly in the investments underlying the derivatives. A relatively small price movement in an underlying investment may result in a substantial gain or loss. The Fund should only be considered as one element of a complete investment program. An investment in the Fund should be considered speculative. The Fund’s investment policy of investing in technology and technology-related companies and writing call options involves a high degree of risk. There is no assurance that the Fund will meet its investment objectives or that distributions will be made. You could lose some or all of your investment. In addition, closed-end funds frequently trade at a discount to their net asset values, which may increase your risk of loss.
