I just finished John Bogle's Common sense investing and I think I am convinced that investing in Index Fund is a great idea.

Now, I really thought it would be a simplistic choice but I really was mesmerized to see that there are plenty of Index funds to invest from on Vanguard site itself and most of them are not (All market) funds as the book describes it to be.

However, I simplified my choice between two Indexed

1. S&p 600(Small Cap)
2. S&P 500(Large Cap)

Since S&P 500 is so popular, it is a obvious to invest in it because if you want to cover entire market(almost) then it is the way to go.

BUT after looking at year to year performance of small-cap fund year-to-year since 1994(20 years) it is very clear that small caps have beaten large caps almost every year.

Even the most popular argument against s&p600 that these stocks are more dangerous and volatile is beyond me because in both (2000 and 2008), which is considered the most dangerous period to be in stock market in last 20 years, small cap has beaten large caps.

Any reason to not invest in S&p600?
