Information is power, but too much information can be overwhelming. The secret to do-it-yourself company investment research is to find the most reliable and relevant sources of free information.

The recently updated Moneysmartz Major Company Information category provides links to market research leaders offering both free and for-fee resources to help you get under the hood of potential equity investments.

A great place to start and meet most of your research needs is Yahoo! Finance. Once on the site, enter the ticker symbol of your target company or do a search to find their ticker symbol, and click "get quotes." For example, here's what you will find after entering GE. The Yahoo! Finance GE page includes charts, quotes, news and information, company information, analyst coverage, ownership, and financial information.

Visit the Securities Exchange Commission Edgar database for free access to financial and related filings by public companies. Stock pickers can roll up their sleeves and dig into the SEC information.

Finally, if you prefer a short and sweet synopsis of your favorite company, then visit the Portfolio.com link.

Once you browse through the Moneysmartz Major Company Information category, you will be prepared to turn your information into power and better investment returns.
