Yes, the title sounds very pumpy however it's more effective than DCA.
The TRICK...you'll need the "right" stock or index. It's needs to go UP and Down. Even with DCA...If you start at 100 and it keeps going down over time to 1 or zero. Well, that's no good.
A nice volatile index or maybe ETF (with stocks that won't go out of business is KEY.)
The book is FUN too if your a fan of the stock market and the idea that you can beat the market.
