Dollar-Cost Averaging (DCA) is widely promoted as a safe and simple investment strategy. Investors are told to buy regularly, ignore market fluctuations, and hold for decades.

But there is a fundamental problem.

Traditional DCA only explains when to buy. It never explains when to sell.

If a strategy discusses buying but never discusses selling, it is not an investment strategy - it is merely a capital allocation tool.

In this book, Ruixue Lei examines the structural weaknesses of traditional DCA and explains why the buy-only philosophy often fails in real financial lives. Investors face unpredictable events, changing market regimes, and volatile economic cycles that make the assumed 30-year investment horizon unrealistic.

The book introduces the concept of **Cycle DCA**, a framework that completes the investment cycle by incorporating both entry and exit rules, while maintaining the discipline and simplicity of regular investing.
