With tech evolving at a breakneck pace, sometimes it's hard to keep track of the trends driving the market.

According to a Barclays note issued Wednesday, Jan. 10, there are a few key names to own as "megatrends" take over.

"The good news for 2018 is that many companies we cover look well positioned to benefit from growth in multiple end markets including 5G, AR/VR, OLED, 3D sensing, Next Gen Automotive, Next Gen Consumer Electronics/IoT and Cyber/AI," analysts wrote.

Coherent Inc. (COHR) is Barclays' top pick and a "key winner" in the advent of OLED panels, which analysts said remain in just the beginning of early stage adoption.

Orbotech Ltd. (ORBK) is a "significant winner," analysts wrote, which will benefit from all of the aforementioned megatrends. CEVA Inc. (CEVA) , Corning Inc. (GLW) , Lumentum Holdings Inc. (LITE) and Finisar Corp. (FNSR) will also benefit from a number of the trends.

Barclays upgraded Lumentum to overweight with a $67 price target on shares.

"We were slow to jump on the 3D sensing bandwagon and spent 2017 on the sidelines," analysts added. "With the first leg of the iPhone X played out, we think investors should take advantage of the current stock price to add to positions in anticipation of strong results for the next 12-18 months as LITE remains the market share leader at Apple Inc. (AAPL) and seems well positioned to take advantage of other opportunities."

With potential upticks in North America and China, telecom is better positioned in 2018 than datacom, where there will be good volume but tough pricing, analysts wrote.

Barclays moved to downgrade Electronics for Imaging Inc. (EFII) to underweight with a $31 price target. With the challenges of 2017 unlikely to persist into 2018 for the company, there's little room anything "close to flawless execution" for share performance.

EFII will benefit from growth in shipping and packages and fast fashion, along with Kornit Digital Ltd. (KRNT) . Barclays reiterated an overweight rating on Kornit, as "expectations are reset and Amazon.com Inc. (AMZN) hardware sales could provide upside in 2018 as Pennsylvania and later Europe come online."
