This is an easy question to answer and a tough question to answer.
It's easy as not all markets around the world trade in the same direction at the same time. The challenge is to know which ones are currently the leaders and which are the laggards. Then you need to decide if you are going to invest in stocks only or if you want to own bonds and any other assets If you are going to do this on your own and do a good job of it, you will have to give up your day job. An alternative is to hire and supervise someone to do it for you.
The hard part of the answer is, even if you just stick to the US market, the companies that comprise over half of the Standard & Poor's 500 average derive more than half of their earnings outside the US. In addition, there are numerous companies whose stocks are traded in the US who are actually domiciled overseas. Nestle is the first one that comes to mind.
As for the "split", that is best answered by what you are comfortable with. The provider of my portfolio models currently has 75-80% in US equities, with the balance split between bonds and foreign stocks depending on how aggressive or conservative an investor is. That allocation can and will change based on the strengths and weaknesses of the global markets.
Hope this helps.
