United Microelectronics Stock Forecast

Sell candidate since Jul 16, 2026 Loss -14.63%

The United Microelectronics Corporation stock price gained 0.475% on the last trading day (Friday, 31st Jul 2026), rising from $18.94 to $19.03. During the last trading day the stock fluctuated 6.70% from a day low at $18.82 to a day high of $20.08. The price has fallen in 6 of the last 10 days and is down by -10.45% for this period. Volume fell on the last day by -680 thousand shares and in total, 17 million shares were bought and sold for approximately $318.45 million. You should take into consideration that falling volume on higher prices causes divergence and may be an early warning about possible changes over the next couple of days.

The stock lies in the lower part of a very wide and strong rising trend in the short term, and this may normally pose a very good buying opportunity. If the lower trend floor at $17.31 is broken, it will firstly indicate a slower rate of rising, but may also be an early warning for a trend shift. Given the current short-term trend, the stock is expected to rise 25.60% during the next 3 months and, with a 90% probability hold a price between $21.75 and $38.53 at the end of this 3-month period.

UMC Signals & Forecast

Volume fell during the last trading day despite gaining prices. This causes a divergence between volume and price and it may be an early warning. The stock should be watched closely. Some negative signals were issued as well, and these may have some influence on the near short-term development. The United Microelectronics Corporation stock holds a buy signal from the short-term Moving Average; at the same time, however, the long-term average holds a general sell signal. Since the longterm average is above the short-term average there is a general sell signal in the stock giving a more negative forecast for the stock. On further gains, the stock will meet resistance from the long-term Moving Average at $23.03. On a fall, the stock will find some support from the short-term average at $18.84. A break-up through the long-term average will give another buy signal, while a fall below the short-term average will add another sell signal and strengthen the general signal. A sell signal was issued from a pivot top point on Wednesday, June 24, 2026, and so far it has fallen -32.06%. Further fall is indicated until a new bottom pivot has been found. Furthermore, there is currently a sell signal from the 3 month Moving Average Convergence Divergence (MACD).

Support, Risk & Stop-loss for United Microelectronics Corporation stock

On the downside, the stock finds support just below today's level from accumulated volume at $17.36 and $17.11. There is a natural risk involved when a stock is testing a support level, since if this is broken, the stock then may fall to the next support level. In this case, United Microelectronics Corporation finds support just below today's level at $17.36. If this is broken, then the next support from accumulated volume will be at $17.11 and $15.23.

During the last day, the stock moved $1.26 between high and low, or 6.70%. For the last week, the stock has had daily average volatility of 7.37%.

Trading Expectations (UMC) For The Upcoming Trading Day Of Monday 3rd

For the upcoming trading day on Monday, 3rd we expect United Microelectronics Corporation to open at $19.31, and during the day (based on 14 day Average True Range), to move between $18.24 and $19.82, which gives a possible trading interval of +/-$1.58 (+/-8.64%) up or down from last closing price. If United Microelectronics Corporation takes out the full calculated possible swing range there will be an estimated 8.64% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $19.70 (3.52%) than the support at $17.36 (8.78%), our systems don't find the trading risk/reward intra-day attractive and any bets should be held until the stock is closer to the support level.
