United Microelectronics (UMC) Stock Analysis & Forecast
Nov 4 close
$16.06−0.34 (−2.1%)
Gekko Brief
AI summaryNov 4 closeUnited Microelectronics shares fell 2.1% this week against a backdrop of two competing narratives. On one side, the stock sank 17% after its Q3 earnings call, as a 61% sequential profit drop and a projected 2027 average selling price increase of 10% fell short of institutional expectations of 15% to 20%, even as revenue and wafer shipments missed estimates despite higher utilization. On the other, UMC approved an additional $3.2 billion capital budget to expand mature and specialty process capacity, and secured major photonic integrated circuit orders of up to 10,000 wafers from Zhongji Innolight and SILITH, with unit pricing reported at seven times conventional processes.
UMC closed at $16.06, sitting between its 50-day average of $21.47 and its 200-day average of $17.15, after a one-month return of -30.7% and a three-month return of -16.4%, against a six-month gain of 5.5% and a one-year gain of 104.8%. The GekkoIndex reads 73.7, placing the stock in the Buying zone. Gekko Fair Value stands at $15.76, putting the current price 1.9% above that level.
The next earnings report is scheduled for 27 January 2027, 83 days out and beyond a typical 20-trading-day holding window. No insider, Congress, or unusual options activity appears in the current windows. Seasonally, the next 20 trading days have averaged a 6.1% gain over the past 5 years, rising in 4 of those years, a pattern worth noting alongside the stock's typical 20-day move of 6.8%.

About United Microelectronics
United Microelectronics manufactures semiconductor wafers on a contract basis for other companies rather than designing chips under its own brand. Its work spans the early stages of circuit layout and mask production through to wafer fabrication, assembly, and testing, making it a full-service partner for firms that need chips physically produced.
The company serves two broad types of customers: integrated device manufacturers that handle both design and production internally, and fabless firms that focus only on chip design and rely on outside partners for manufacturing. United Microelectronics runs operations across several regions, including Taiwan, Singapore, China, Hong Kong, Japan, the United States, and Europe, supporting this global customer base.
United Microelectronics was founded in 1980 and is headquartered in Hsinchu City, Taiwan. Its shares trade under the ticker UMC.
