The Invesco QQQ Trust holds the 100 largest nonfinancial stocks on the Nasdaq exchange, with a focus on tech companies. The ETF can be highly volatile and is currently very concentrated. While successful, it may not be suitable as a core holding due to lack of diversification. The expense ratio is 0.20%, higher than some S&P 500 index-tracking ETFs. The portfolio is heavily weighted towards tech, with the top 10 holdings accounting for nearly 53% of assets. Consider adding it as a complement to a diversified ETF, but be aware of its potential for volatility.

Before investing $1,000 in the Invesco QQQ Trust, note that it may not be the best choice according to the Motley Fool Stock Advisor team. They have identified 10 stocks with potential for significant returns, separate from the QQQ Trust. The ETF has a history of outperforming the Vanguard S&P 500 ETF, but with higher volatility. It may not be ideal as a core holding, but could be a long-term investment for those seeking exposure to the technology sector.
