The greatest investors are those who see something before others do. And just as many of us have dropped the emerging markets for opportunities on more familiar shores, Tactical Allocation Group's Paul Simon thinks he's having one of those visionary moments.

"The other part of the (emerging markets) story that's not well known is that there's more trade with each other and amongst themselves than with the developed world," Simon says. "So their dependence on the U.S., Europe, Japan is not as great as a lot of investors think."

The short trading week on Wall Street doesn't mean there's any shortage of news for traders and investors to get through, and we've got some familiar themes to cover.

Let's start with Greece. New week, new story, new worries. Or hopes. In other words, the roller coaster continues. This time the news appears to be on the good side, with indications that a deal to help the country avoid default may be near. That was helping stocks out in the U.S. But there's still plenty of anxiety about the country and the rest of Europe, and that reality will no doubt continue to play out in the markets as long as there's any uncertainty.

In the states, economic news was heavily influencing the conversation, and not necessarily in a good way. The S&P/Case-Shiller housing index was dreadful, meaning the home slump that became painfully obvious in the 2007-08 period continues to not only drag on, but show at least some signs of actually worsening. Speaking of worsening, Americans aren't feeling terribly optimistic aboout the overall economy these days, according to the latest survey of consumer attitudes.

Maybe we should just go back to the start of that three-day weekend.
