Schwab US Large-Cap ETF remains a buy, offering diversified exposure to top global companies and outperforming the S&P 500 with a 29.6% annual return. SCHX is heavily weighted toward technology (34.26%), positioning it to capture AI-driven growth, while quarterly rebalancing enhances responsiveness to market changes. The ETF's broad holdings dilute individual stock impact, reducing volatility but potentially underperforming more concentrated tech indices like QQQ during strong rallies.
