In this video from Monday's Investor Beat, host Chris Hill and Motley Fool tech and telecom bureau chief Evan Niu look at the biggest trends in the tech sector as 2013 comes to a close.

While tech hardware companies such as Apple (AAPL -0.57%) and Samsung are trading at very modest price to sales multiples, P/S ratios for service companies in the tech sector such as Facebook (META 1.54%), Yelp (YELP -0.38%) or Pandora (P) are sky-high. Evan sees this as one of the many signs that both investor and consumer sentiment is undergoing a major shift. Evan delves into what could be causing this shift, highlighting the most popular hardware devices of the day, and why investor excitement in these devices could be waning.
