The company's first major blow came this year when Walt Disney (DIS) - Get Report handed the Barbie maker's long-held Disney Princess contract to rival Hasbro (HAS) - Get Report . Mattel had made the Disney Princess dolls since 2000.
Last week, analysts at Zacks Investment Research cut Mattel stock rating to a "sell" from a "hold," noting that the shares have underperformed in its industry group this year.
"Lack of innovative schemes for brand awareness and brand innovation has been hurting the company's revenues and point of sale momentum," Zacks said in a Dec. 20 note. "Also, sluggish performance of certain segments and brands along with [the] loss of the Disney deal has added to the concerns."
Historically, Mattel has put up an earnings per share growth rate of 3.1%, compared to the industry average of about 21%. The company is expected to grow at a rate of 1.4% for the 2016 full year, while the industry average is estimated to increase at a 14% rate, according to the Nasdaq.

On Christmas morning, many parents who purchased the app-controlled, voice-monitored Barbie Hello Dreamhouse - users can control the functions of the house by voice command - were far from pleased with Mattel. When children went to play with the high-tech doll house, they were greeted with an "Error Code 18" message, which turned out to be a wireless network issue that disabled the voice control.
Twitter user @jimmymcarthur wrote "A true modern Christmas. I'm tweeting @ToyTalk and @Barbie about my problems with our Dreamhouse wifi. WTF kind of world is this?"
The company behind the technology for the doll house, ToyTalk, responded to the complaints in a statement that advised users to turn the Barbie Hello Dreamhouse off for 15 seconds and then power it back up.
Mattel did not return a request for comment so it is unclear how many people were affected.
And Hasbro's Pie Face Showdown - in which two players compete to find which will be smushed in the face by a dollop of whipped cream - was Amazon's (AMZN) - Get Report best-selling toy during the Black Friday, Cyber Monday shopping weekend.
