Bottom line
UMC Technical Analysis Summary
UMC (United Microelectronics Corporation) shows a moderately bullish technical picture on the daily timeframe, but the weekly chart reveals a more cautious backdrop. On the daily chart, price at 8.52 is trading above SMA20 (8.18) and SMA50 (8.05), indicating constructive short-term momentum. However, price remains below SMA200 (8.71), confirming the longer-term trend is not yet fully bullish. RSI14 at 57.42 on the daily chart is in neutral-to-bullish territory, while the weekly RSI at 51.80 has just climbed above the 50 midline. The daily MACD is positive with the MACD line at 0.10 above the signal line at 0.06 and a rising histogram of 0.04, suggesting gradual improvement in momentum. Key resistance sits at SMA200 (8.71) and the 60-day high of 8.95. Support levels are at 7.95 (20-day low) and 7.52 (60-day low). A sustained move above 8.71 with volume would be needed to confirm a broader trend shift.

Daily (July 14, 2026)
- Trend
- Cautiously bullish. Price at 8.52 is above SMA20 (8.18, +4.16%) and SMA50 (8.05, +5.84%), but remains below SMA200 (8.71, -2.18%). SMA20 and SMA50 are sloping upward while SMA200 is flattening, suggesting the short-term trend is improving but the long-term trend has not fully turned. The bullish alignment of shorter SMAs above longer ones is a positive development.
- Momentum
- Bullish with moderate conviction. RSI14 at 57.42 is above the 50 midline, indicating bullish bias without overbought conditions. MACD line at 0.10 is above the signal line at 0.06, and the histogram at 0.04 is positive and rising, confirming gradual improvement in momentum. The MACD values are small relative to price, reflecting the stock lower volatility profile.
- Volatility
- Low to moderate. ATR14 at 0.22 (2.58% of price) suggests average daily movement around 2.6%. Bollinger Bands (7.82 to 8.74) are moderately narrow, indicating normal volatility conditions with price trading near the middle to upper band.
- Volume
- Slightly below average. Latest volume of 6,847,200 is 74.1% of the 20-period average (9,241,800), indicating reduced participation in the recent uptrend. Volume confirmation remains a watchpoint.
Assessment
The daily chart shows a stock that is building constructive momentum after trading in a range. The price has reclaimed both SMA20 and SMA50, and the MACD is positively aligned. The key challenge is the SMA200 overhead at 8.71, which has acted as resistance. The below-average volume during the rally reduces conviction, but the overall structure is the most positive it has been in months. A clean break above SMA200 with volume would be a significant technical development.
Weekly (July 6, 2026 week)
- Trend
- Neutral with improving bias. Price at 8.46 is slightly below SMA20 (8.54), SMA50 (8.62), and SMA200 (8.58), reflecting a market that has been range-bound for an extended period. The SMAs are converging and flattening, which often precedes a breakout. The stock has been oscillating in a broad range roughly between 7.50 and 9.00 for most of the past year.
- Momentum
- Neutral. RSI14 at 51.80 has moved above the 50 midline, a modest improvement from the neutral-to-weak readings seen in prior weeks. MACD line at -0.01 is near a crossover with the signal line at -0.04, and the histogram at 0.03 is positive, suggesting bearish momentum is fading. The MACD is approaching a potential bullish crossover.
- Volatility
- Moderate. ATR14 at 0.35 (4.14% of price) reflects typical weekly ranges for a mid-cap semiconductor stock. Bollinger Bands (7.82 to 9.28) are moderately wide with bands converging slightly, consistent with the consolidating price action.
- Volume
- Near average. Weekly volume of 38,215,400 is 91.7% of the 20-week average (41,676,500), indicating typical participation levels. No unusual volume patterns are evident.
Assessment
The weekly chart reveals a stock in a prolonged consolidation phase. The converging SMAs and the RSI hovering near 50 suggest the market is undecided on direction. The potential bullish MACD crossover on the weekly chart is worth monitoring, as it would be the first such signal in several months. The 52-week position at 49.3% reflects a stock trading near the middle of its annual range, consistent with the neutral assessment. A weekly close above SMA200 (8.58) and then above the 60-week high (9.00) would signal a meaningful trend change.
