These 4 Stocks Are Tied to the Smartphone in Your Pocket

The article analyzes four companies profiting from smartphones: Apple, Qualcomm, Corning, and Arm Holdings. Apple's iPhone revenue grew 17% year-over-year, but growth is slowing and margins are pressured by rising memory costs. Qualcomm's handset chip revenue fell 26% and is expected to decline further as Apple develops its own modems. Corning's phone glass business is smaller than its optical communications segment, which is growing rapidly. Arm's smartphone royalties declined as memory prices impacted the market. Of the four, only Apple reported growing phone sales, making it the author's preferred choice despite its premium valuation.
