It's that time again, Fools -- time for my daughters Hannah and Ainsley to buy another stock. You may recall that my girls have been investing for quite some time now. In fact, today, their portfolio holds shares in six different companies and yes, thanks to The Motley Fool's own Scorecard, we know that they are beating the market quite nicely.

Our typical process is that together, on a quarterly basis, we whittle down the companies to a list of four "finalists" from which they ultimately choose the winner. The only standing rule is that it must be a stock that they don't already own. Think of this as a standing lesson in the value of diversity.

This quarter, we thought it would be fun to have one of their finalists come from the wisdom of crowds... and this is where you come in. We want your vote. The stock that receives the most votes will make it to the girls' final four. So far, they have chosen Chipotle Mexican Grill (CMG 0.40%) as one of their finalists. This winner will join Chipotle, along with two other stocks that we have yet to decide on.

I'd like to say that they are really homed in on the fact that Chipotle just brought in better than 20% top-line growth in the fourth quarter of 2013, which translated to 30% earnings growth, along with the fact that the company has almost completely removed all genetically modified organisms, or GMOs, from its food. But honestly, I think it's mostly because they like the food and know that we spend money there on a pretty regular basis. But hey... that's OK by me. As both girls are quick to point out, whenever I or my wife buy something from Starbucks (they own shares in the coffee king), we're paying them in the process.

But I digress. Once we have their final four, we'll make a new video for Fool.com (similar to the one right here), in which we'll announce the stock they'll be buying for their quarterly purchase. Voting will close on Feb. 26, so please, Fools, take a moment to click on over to this quick and easy Survey Monkey survey, and tell us which stock should be in their final four: Facebook, Amazon.com, Twitter, or Panera Bread. And thank you for your participation!
