You don't. But the author of the article, Nicholas Vardy, can profit. Because he runs an emerging market fund that is linked to in the article.
So if you buy his argument and invest in his "Global Gains" fund, that's more management fees for him.
Who knows? Vardy might be right and now is the ideal time to buy emerging markets. But I'm a tad bit suspicious. I've never heard of a stock fund manager advise folks to sell their stocks. All they say is buy now.
I re-read the article just to get another perspective. Yes, I realized he was making money on his customers but he made it sound like he was making money on stocks at this point by buying now.
He sounds like the Obama administration sales pitch saying the job losses due Obamakare are a good thing.
