The following video is from a very special Halloween edition of Investor Beat, in which host Chris Hill and Motley Fool analysts Tim Hanson and Matt Koppenheffer dissect the hardest-hitting investing stories of the day.

Facebook's third-quarter results looked impressive on paper. Immediately after reporting last night, the stock soared more than 15%. But comments on the analyst conference call by Facebook's finance chief sent the stock in the other direction. In today's spooky lead story on Investor Beat, Tim and Matt discuss whether a decrease in daily use among younger teenagers is a real problem for Facebook and what growth levers the company can still pull from here.

Our analysts also discuss four stocks making moves on the market today. Visa's fourth-quarter revenue rose 9%, but profits fell 28%. Starbucks posted some strong numbers: Fourth-quarter profits are up 34%, with global same-store sales up 7%. Shares of hhgregg took a hit, with second-quarter profit and revenue for the electronics retailer both lower than expected. And Carbo Ceramics exploded today, with the boom in North American fracking driving third-quarter results up way above what analysts expected.

And finally, Matt tells investors why he'll be watching shares of AIG this week, and Tim takes a look at one exciting IPO on his radar that investors should be aware of.
