NVIDIA

NVIDIA has had a great year, surging more than 74% YTD, Google Finance data shows. Because of this sharp increase, the company's price-earnings ratio (P/E ratio) had climbed to roughly 46.6 at the time of report.This figure was far higher than the Standard & Poor's 500 Index's P/E ratio of 25.6. 

While NVIDIA may be a bit pricey, analysts have predicted its sales will climb 37% the next fiscal year, as the company's chips benefit from widespread demand, Fortune reported. 

Cisco

Cisco, which has been making forays into cloud computing and cybersecurity, expects that its revenue will grow this quarter for the first time in two years, according to Fortune. This development could make shares of this networking giant, which has been paying notable dividends, far more attractive. 

After climbing more than 25% YTD at the time of report, the company's P/E ratio stands at 19.81, Google Finance data reported. 

Applied Materials

While semiconductor makers like Applied Materials have at times traded at a discount because their industry can suffer long downturns, Ian Mortimer, co-manager of the top-­performing Guinness Atkinson Global Innovators Fund, has predicted that the surging relevance of Artificial Intelligence could make the demand for semiconductors far more consistent, according to Fortune. 

Even though shares of Applied Materials have surged approximately 57% YTD, the company's P/E ratio is 16, Google Finance data shows. (For more, see also: The World's Top 10 Semiconductor Companies.)

Infineon Technologies

Infineon Technologies AG is a German chipmaker that could enjoy notable headwinds as the automotive industry makes greater use of its sensors for everyday functions ranging from detecting obstacles to opening and locking doors, according to Fortune. The company, whose shares have climbed more than 57% YTD, has a price-earnings ratio of 33.
