Investing in stocks is the very best way to passively build wealth over a lifetime. But too many think it is more like gambling than sensible wealth-creation. The stock market's gyrations of late can certainly reinforce the argument that it's too risky a bet for the family nest egg.

Can the US economy continue to plow ahead against global headwinds of the slowing economies of China, Europe and the developing world? Can it withstand the rapid devaluation of the oil industry and commodity prices? And most important of all, can it remain healthy during a period of rising interest rates?

Since its peak on May 21st, the S&P has fallen by nearly 10%. Stocks were pretty well behaved in the weeks that followed Fed Chair Janet Yellen's May speech in which she warned that interest rates would likely begin rising this year. But China's equity slide last Monday became the catalyst for a more significant US equity slide of 5% for the week ended last Friday. As of this writing, stock averages are down another 3%.
