Which is fine..but as the math shows, it could be done more efficiently albeit with more risk.~Dope

I agree 100% with the more risk part...
Numerous studies have shown that the average investor significantly underperforms the stock market due to behavioral factors, taxes, fees, and poor timing.
While the stock market returns have been good historically the average investor's return after fees & taxes have been much lower.

DALBAR's analysis suggests that since 1988, the stock market's average return has been about 10% per year.
However, the average stock fund investor has earned only about 4.1% per year after fees and behavioral impacts.

And there is always the possibility that the equities market can go nowhere for extended periods of time:
The Japanese market, took almost 34 years to regain its previous high set in December 1989.
Investors had to wait over three decades to see the market fully recover its losses from that crash, marking one of the longest periods for any major stock market to reclaim old highs.
