Non-U.S. Revenue Percentages...

One of the most important aspects of investing your hard-earned dollars is to ensure that you are diversified to guard against fluctuations in sectors of your portfolio that may be overweighted, such as what happened to a lot of people in 1999 when they were overweighted in tech and what happened to people at Enron who were way overweighted in their own company stock.

It pays to do a little digging because things may not always be as they seem.

For instance, you may be invested in a U.S.-based company thinking that you have covered the U.S. portion of your portfolio, when in fact, most of that company’s revenue is coming from more unstable foreign sources.
