You could win a free subscription to Stock Advisor by leaving a comment below. We’re announcing 12 contests in 12 hours, so check back at Fool.com for more chances to win.

You might be an investor if you click over to Fool.com several times a day and find yourself compelled to leave a comment about:

  • how The Motley Fool's writers don't understand the value of Sirius (NASDAQ:SIRI) stock,
  • how the U.S. government is clueless on how to run a country,
  • how Apple's (NASDAQ:AAPL) iPhone or Motorola (NYSE:MOT) and Google's (NASDAQ:GOOG) Droid will defeat the opposing competitor in a smartphone brawl, or
  • how Citigroup (NYSE:C) will rise to $20 by year's end.

Investors come in varieties about as different as peanut butter and fried eggs. While we're all looking for investing opportunities in the market, each individual investor has a different composite of investing style, risk level, and "stomach-ability" for his or her investments.

Remember the last time your uncle told you about an investment he made ... and you cringed? Or maybe you have a friend whose fine collection of The Wall Street Journal and Money Magazine is always proudly displayed on his coffee table (everyone knows one!). Maybe you yourself can't go anywhere without your HP-12 financial calculator. It's hard not to make observations about what investors are like. Now you can win a prize for sharing those humorous insights.

Comment below in 250 words or fewer about your favorite investor stereotypes, and you could win a digital subscription to The Motley Fool's flagship newsletter service, Stock Advisor (a $149 retail value). The contest ends at 8:00 p.m. EST on Thursday, Dec. 17. The members of our editorial staff will select their favorite comment, and the winner will receive a free one-year subscription to Stock Advisor. All contest rules can be found here.

Let's hear those investor stereotypes in the comments box below!

Katrina Chan owns shares of Apple but none of the other companies mentioned in this article. She also thought -- after writing it -- that maybe peanut butter and fried eggs might make a good flavor combination. Google is a Rule Breakers recommendation, and Apple is a Stock Advisor pick. The Fool has a disclosure policy that's hip to investor-speak.
