Next decade will be a good one for investors

Even the most practiced soothsayer will struggle to make any detailed predictions for the next 10 years. It's hard enough to know what will happen in the markets in January 2010, never mind December 2019.

The main thing investors need to know about the coming decade can be summed up in one of those pithy Twitter updates. Will it be good or bad for stocks? Everything else is extraneous.

The answer? Good. A shortage of capital from any source other than the stock market; moderate but persistent inflation; and the probability that economic growth will be stronger than many economists expect means that "the 10s" will be a time when equities start to have some rocket fuel in their engine again.
