Lagging its rivals,fast food giant McDonald's needs to come up with new ideas to satisfy investor appetite, says Saxo Bank’s head of Equity Strategy Peter Garnry.

McDonald’s comes out with fourth quarter earnings on January 23. It’s forecast to report earnings of $1.21 billion - or earnings per share of $1.24 – and revenues of $6.7 billion.  

While McDonald's has seen lower sales and fewer customers, the fast food industry in general is thriving and remains attractive for investors, says Peter Garnry.
