Key Points The Nuveen NASDAQ 100 Dynamic Overwrite Fund is one of the earlier covered call closed end funds to have launched, having begun in 2007. The Nuveen NASDAQ 100 Dynamic Overwrite Fund (NASDAQ: QQQX) premiered in 2007, and has been solidly performing in its tracking of the Nasdaq 100 Index ever since. The Nasdaq 100 Index is a popular stock index of Nasdaq listed stocks. However, unlike with the S&P 500, few of the stodgier banking, insurance, and defensive companies trade on Nasdaq, thus making the Nasdaq 100 more aggressively weighted towards technology. On the plus side, this results in ample call option underwriting premiums that supply the fuel for QQQX dividends, which equate to a yield of 8.23% as of market price at the time of this writing.
