The biggest risk today isn't necessarily buying at the top; it's confusing a strong market with a risk-free market. With AI stocks driving much of the S&P 500's gains, index diversification doesn't completely eliminate concentration risk.

Historically, investing a lump sum has tended to outperform spreading investments over time because markets rise more often than they fall. However, DCA can reduce emotional pressure and help investors avoid panic when prices decline.

If I had $10,000, I'd invest a portion upfront and deploy the remainder over the next few months, while keeping an emergency fund separate. I'd also continue investing regardless of short-term headlines.

Why? Because waiting for a 10% correction sounds sensible until the market rises another 15% without giving you an entry point.

The real edge isn't predicting tomorrow's price. It's having a strategy you can stick with for the next 10–20 years
