6-Day Rally Sends Corning Stock Up 15%
Corning (GLW) stock hit day 6 of a continuous streak of days with gains, with cumulative gains over this period amounting to a 15% return. The company has gained about $9.1 Bil in value over the last 6 days, with its current market capitalization at about $70 Bil. The stock remains 105.8% above its value at the end of 2024. This compares with year-to-date returns of 17.3% for the S&P 500.
Corning’s recent streak reflects robust demand for its Gen AI products in Optical Communications, with Q3 enterprise sales up 58% year-over-year. This, coupled with an early achievement of its 20% operating margin target from the “Springboard” plan and a positive Q4 outlook, has fueled strong investor confidence.
What is the point? Momentum often precedes conviction. A multi-day win streak can signal growing investor confidence or spark follow-on buying. Tracking such trends can help you ride the strength, or prepare for a well-timed entry if momentum fades. Our take: There are only a couple of things to fear in GLW stock given its overall Moderate operating performance and financial condition. But keeping in mind its Very High valuation, we think that the stock is Unattractive (see Buy or Sell GLW).

While GLW stock looks attractive given its winning streak, investing in a single stock without detailed, thorough analysis can be risky. The Trefis High Quality (HQ) Portfolio, with a collection of 30 stocks, has a track record of comfortably outperforming its benchmark that includes all 3 — the S&P 500, S&P mid-cap, and Russell 2000 indices. Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.
