Corning (GLW) stock has been one of the standout performers of 2026, fueled by surging demand for AI-driven optical networking. But the last five trading sessions have been rough.
The stock fell 4% to $186.96 on Tuesday, extending a losing streak that has now wiped out $52.4 billion in market value. The four-day decline totals 24%, putting GLW about 28% below its all-time high of $271.78 set on June 30.
The selloff is part of a wider unwinding of AI-related trades across the market, dragging chip stocks and optical networking names lower together.
Despite the pain, GLW is still up 114% in 2026 and has gained over 251% in the past 52 weeks. That context matters when looking at what analysts are saying right now.
Oppenheimer analyst Martin Yang raised his price target to $230 from $210 on Tuesday, keeping an Outperform rating. He called the AI infrastructure pullback “an attractive entry point” into GLW’s long-term growth story.
Yang argues Corning is well placed to benefit from near- and mid-term demand for optical fiber as customers ramp capital spending to support generative AI infrastructure.
Bank of America’s Wamsi Mohan also moved his target higher, raising it to $243 from $223 on Monday while reiterating a Buy rating. His focus heading into earnings is whether Corning’s optical networking segment can sustain growth beyond the near term.
“We expect the quarter to reinforce that optical demand remains firm,” Mohan wrote.
Corning’s AI story isn’t just analyst optimism. The company has locked in some major agreements recently.
In June, Corning and Amazon announced a multibillion-dollar deal to produce optical fiber for data centers. Before that, Nvidia made an investment worth up to $3.2 billion in May to help expand Corning’s optical networking manufacturing in Texas and North Carolina.
Earlier this year, Meta signed a $6 billion agreement with Corning for cabling, optical fiber, and connectivity solutions across its data center network.
These deals underpin the bull case. They’re not hypothetical — they’re signed.
From a technical standpoint, Barchart currently gives GLW a 100% Buy opinion, and the stock carries a Weighted Alpha of +212.87. Revenue is projected to grow 15.48% this year, with earnings expected to climb 26.83%.
Wall Street analysts tracked by Barchart show 8 Strong Buys and 6 Holds, with price targets ranging from $167 to $270. Morningstar is the outlier, rating the stock 26% overvalued with a fair value estimate of $155.
Q2 earnings will be the next key moment for GLW investors, with optical networking demand set to be the main focus.
