When it comes to conducting research on your investments, Sec.gov is literally your best friend. I often browse the Edgar database when I need to dig up some research on any public traded companies. If you've ever been afraid of sec.gov, here's a basic tutorial (w/ pictures) on how to find those verbose SEC quarterly filings.
Step 1: Go to SEC.gov
ALL SEC Quarterly filings are listed at sec.gov under the Edgar database.
Step 2: Click Companies and Other Filers
Step 3: Type in Company Name or Ticker of the Publicly Traded Security
In this example, I'm using General Motors (GM).
Step 4: Type in 10-Q and Click Retrieve Selected Filings
Step 5: Click View Reports in HTML
That's it! Please bookmark this tutorial if you found it useful. Thanks!
