Corning, a glass maker since 1851, has seen its shares rise 44% in 2026, versus 16% for Nvidia, as demand grows for its fiber-optic cables used in AI data centers. The article says data centers are shifting from copper to fiber, and Corning’s new Multicore Fiber packs four cores into one strand, cutting cable count by 75% for the same performance, while clusters of over 130,000 GPUs need about 50% more fiber content. Meta plans to buy $6 billion of optical connectivity products from Corning over the next few years, and Amazon signed a deal of a similar size. In the third quarter of 2026, Corning’s core revenue rose 19% to $5.1 billion and optical communications revenue rose 44% to $2.4 billion, with that segment’s core net income up 80% to $532 million. Corning’s P/E ratio is 40.6 based on the last four quarters, versus 27.5 for Nvidia, but on Wall Street’s 2027 earnings estimate of $4.40 per share, the forward P/E is 28.7, which the article considers more reasonable.

- Corning (GLW) Stock Could Be 31% Below Fair Value As AI Fiber Demand Builds
Corning shares have risen 436.5% over the past three years on AI infrastructure demand, raising the question of whether the current price of $134.92 is backed by its cash flows. The article's discounted cash flow model, based on about $2.5b in latest twelve-month free cash flow and projected growth through 2030, gives an intrinsic value above the current share price. It argues that the long-term Meta supply agreement and AI data center work shown at the 2026 OCP Summit may already be largely reflected in the stock. The piece also points to Corning's 61.2x P/E as a different valuation view and directs readers to Simply Wall St Narratives to compare the assumptions behind the price.
- Prediction: Here's Where Corning Stock Will Trade in 2030
Corning shares have fallen since late June to about $132, under half the 52-week high of about $272. In its October 27 third-quarter report, the company said core sales rose 19% to $5.08 billion and adjusted EPS rose 36% to $0.91, topping management's forecast; optical communications sales grew 44%. The author estimates the stock could reach about $187 by end-2030, assuming 2030 adjusted EPS of $7.50 and a P/E ratio of 25, or roughly 9% annual returns before dividends. The author notes that investors usually pay less per dollar of earnings as a company matures; at a P/E of 20, the price would be about $150, or about 3% a year. The author views the stock as reasonably priced for its earnings growth, while remaining cautious about the valuation and noting dependence on AI spending by large tech firms.
- Buy Corning on Solid Q3 Earnings, Guidance and AI Photonics Space Rally
Corning reported third-quarter 2026 core earnings of 91 cents per share, up 36% year over year and above the Zacks Consensus Estimate of 89 cents, while core revenue rose 19% to $5.08 billion. Optical Communications sales jumped 44% to $2.38 billion on AI infrastructure demand, and Enterprise Networks revenue rose 84%. Core gross margin expanded 150 basis points to 40.5%. For the fourth quarter of 2026 the company guides core sales of $5.2 to $5.3 billion and targets a $30 billion annualized sales run rate by the end of 2028. Zacks ranks Corning #1 (Strong Buy), and the average short-term brokerage target implies a 41.6% increase from the $131.20 last close.
- Can AI Fiber Still Deliver? Corning Faces High-Stakes Q3 Earnings Test Oct. 27 as Valuation Stretches
Corning (NYSE:GLW) reports third-quarter results before the open on Tuesday, Oct. 27, after shares fell 19.93% over the past month and trade at about 38x 2026 consensus EPS. Last quarter core EPS of $0.78 beat the $0.7538 estimate for a fifth straight quarter, but revenue of $4.505 billion missed the $4.63 billion consensus despite 16.6% growth. Optical Communications sales rose 32% to $2.072 billion, and management raised its Springboard Plan to annualized sales run rates of $20 billion by end-2026, $30 billion by 2028 and $40 billion by 2030. The article says the report must show whether Optical growth stays at 30%-plus and whether new hyperscaler deals with Meta Platforms, Amazon and NVIDIA follow. Solar posted a $7 million net loss after a $30 million expense from a wafer shutdown, while capital spending is rising.
- Can Meta's Fiber Partner Corning Capitalize On Rising AI Fiber Prices?
Prices for specialized AI data-center optical fiber are forecast to average more than five times their 2025 levels this year, and Corning has a supply agreement with Meta worth up to $6 billion. Its Optical Communications sales rose 32% to $2.07 billion in the second quarter, while segment net income surged 77% to $438 million. CEO Wendell Weeks said higher fiber prices are not the main driver of profitability; higher-value connectivity products are. TrendForce forecasts a global fiber shortage of 180 million fiber-kilometers this year, with capacity utilization at 92% and inventories at one month's supply, while expansion takes 18 to 24 months. Despite strong demand, Corning shares have lost roughly half their value since a June record high, though UBS, Citi and Bernstein have set price targets ranging from $140 to $220.
- Corning Is Moving Beyond Fiber Cables. Can AI Networking Pay Off?
Corning (GLW) is extending beyond fiber cables into optical components inside AI systems, having demonstrated optical connectivity with Lumentum and Astera Labs on October 12 and partnered with Nvidia on a planned tenfold expansion of optical connectivity capacity in the US. Its Optical Communications sales rose 32% year-over-year to $2.07 billion in Q2 2026, and management sees a potential $10 billion revenue opportunity by 2030 from a photonics platform, though timing and adoption remain uncertain. Still, the valuation is elevated, with a forward non-GAAP P/E of 44.81x, about 84% above its 5-year average of 24.31x, while analysts expect EPS to grow 30.41% in December 2026 and 33.02% in December 2027. The article notes that slower AI spending or delayed CPO adoption could pressure the stock.

- Pfizer Just Hit a 52-Week High. Is the Turnaround Finally Real?
Pfizer (PFE) shares are up 20% year to date as the company emerges from its post-pandemic slump, though the article says the recovery is still at an early stage. Last quarter, revenue rose 3% and beat Wall Street expectations, helped by Eliquis and cancer drugs that offset lower COVID-19 product sales. Pfizer raised its full-year revenue guidance, reiterated adjusted EPS of $2.80 to $3 per share, and sees up to $6.7 billion in cost savings through 2029. The stock trades at about 10 times estimated 2026 earnings, while sell-side forecasts see 2027 EPS slipping from $2.96 to $2.88.

- Wall Street's favorite stocks are in their worst slump since 2010: Chart of the Day
Piper Sandler's data shows S&P 500 stocks with the largest share of analyst Buy ratings have trailed those with the smallest share for most of 2026, a year-over-year gap that is the third-worst in its data back to 1995, behind only 2001–02 and 2010. This week Alphabet had its worst month in history, Intel its worst day since 1974, and the Nasdaq its biggest daily drop since June, as Big Tech results revived worries about AI spending. Six of Piper's nine favored names are down this year, the exceptions being Nvidia, Arista Networks and Comfort Systems, while nearly all of the least-loved stocks are up. Because most investors own these favorites through index funds or 401(k)s, the slump affects many portfolios, and the article adds that when analyst enthusiasm is already priced in, disappointments sting more. Piper's favorites had been up nearly 18% on average in spring before the AI trade began to unwind.
- Coca-Cola and Procter & Gamble Are Up This Month. Which Dow Dividend Stock Is the Better Buy Now?
Coca-Cola (KO) and Procter & Gamble (PG) have both risen sharply over the past month or two, which the author attributes mainly to investors moving from AI-related stocks into defensive consumer staples after a mid-October selloff. P&G's fiscal first-quarter results beat estimates, with organic sales growth accelerating to 4% on higher volumes, while Coca-Cola's Q3 revenue rose 7% to $13.4 billion and it raised its 2026 guidance to at least 5% organic revenue growth and at least 11% non-GAAP earnings growth. P&G closed its $3.9 billion acquisition of Thorne this month, and Coca-Cola will take over KFC's U.S. beverage business in 2027, ending PepsiCo's supply role. The author argues the rally reflects short-term sentiment rather than a verdict on long-term prospects, and views P&G as more reasonably priced at 23 to 24 times forward earnings versus 26 to 28 times for Coca-Cola, which has risen more than 32% this year.
