If you're anything like me, you have trouble deciding sometimes. Should you invest in this company or that one? This region or that one? Too many times, I'll end up grabbing a little of this and a little of that. While that solves that problem, it does result in having more than an ideal number of holdings.

One way around such overdiversification is to invest in some indices. Broad-market indices, such as the S&P 500 for U.S. stocks or the MSCI EAFE Index for international stocks, give you immediate diversification into hundreds of different companies. Getting into those indices is as easy as buying shares of SPDR Trust (AMEX:SPY) or iShares MSCI EAFE Index ETF (NYSE:EFA).

You can be a little more focused, though, if you want. For example, if you're drooling over massive opportunities in India and China, you might look into the First Advisors LSE ChIndia Fund (AMEX:FNI) -- a new exchange-traded fund (ETF). It offers instant exposure to two countries via a single investment and sports a relatively low expense ratio (annual fee) of 0.60%. The fund aims to hold the 25 most liquid stocks in each of India and China, for a total of around 50 holdings. Of course, since the fund just came out in May, it doesn't have much of a track record yet.

Gary Gordon of etfexpert.com offered this caution for the fund:

However, there are significant dangers with the FNI basket, including: (1) a 37% exposure to information technology and a 14% exposure to telecom that may put one directly in the line of fire for a "tele-tech" implosion, (2) a price/book of 7 and price/earnings of 45 looks lofty in the best of circumstances, and (3) indirectly investing in the China/India boom via the tigers (Malaysia, Singapore, Taiwan, Korea) and the iShares MSCI Australia Fund (NYSE:EWA) could prove more lucrative with less risk.

Another option for the undecided or those seeking simplified international exposure are "BRIC" funds, offering Brazil, Russia, China, and India. The Claymore BNY/BRIC Fund (AMEX:EEB), for example, will give you fast exposure to those economies, which represent some 40% of the global population.

What to do
In general, it's a very good idea to keep a portion of your portfolio invested internationally. Mutual funds and ETFs offer a simple way to do so.
