Should You Buy QQQ While Tech Stocks Are Still Near Their All-Time Highs?

The Invesco QQQ Trust has delivered strong 5-year returns of 111%, but faces valuation concerns with a weighted-average P/E ratio of 36.5. The ETF's heavy exposure to unproven AI spending trends, particularly through top holdings like Nvidia, Microsoft, and Amazon, poses risks if returns disappoint. Investors should adopt a long-term perspective and use dollar-cost averaging rather than trying to time the market.
