Here are some helpful links in helping you become a Generation WI$E investor.
Vanguard's Insight - Vanguard, the largest mutual fund company in the U.S. helped pioneer index fund investing and offers information and commentary on investing and personal finance issues. Here, you will find some important info on how to save for retirement, taxes and what the current state of the financial markets mean for long-term investors.
Morningstar's mutual fund section - Morningstar is a large provider of financial information and gained notoriety for engineering the use of "star ratings" to track mutual fund performance. While star ratings have been shown to have little, if any predictive power, the mutual fund section of their website has a wealth of data on most all mutual funds out there. This is a valuable resource to use in looking up fund expense ratios as well as the objective of a fund and its top holdings, among other things.
IndexFunds.com - While a bit more academic than the first two websites, IndexFunds.com is a great resource to use whenever you catch yourself thinking that actively managed mutual funds are a better way to go than index funds. Here, you will find a variety of articles and studies extolling the virtues of index fund investing, as well as many critical research papers on a litany of topics relating to index investing.
Wall Street Journal - While I don't think it's a good idea to actively watch or pay much attention to the Wall Street hype machine on the big television networks or weekly glossy magazines, The Wall Street Journal is a must for financial news. The Journal is the cream of the crop when it comes to financial journalism and their Washington bureau is one of the best in covering the political side of economic decisions. Their economics reports are also top-notch so on the whole, the paper (or the website) is worth reading everyday to stay informed.
