Bottom line
UMC Technical Analysis Summary
UMC (United Microelectronics Corporation) is in a high-volatility pullback inside a powerful longer-term uptrend. On the weekly chart the trend is clearly bullish, with price at 19.03 above SMA20 (17.08), SMA50 (11.68), and SMA200 (7.93), all rising. On the daily chart price at 19.29 has fallen below SMA20 (20.91) and SMA50 (22.15) after peaking near the 52-week high of 28.46, but remains well above a rising SMA200 (12.79). Daily RSI14 at 44.24 and a negative MACD histogram of -0.14 confirm weak short-term momentum, while weekly RSI at 57.48 stays above the 50 midline. Support sits at the 20-day low (16.54), then the 60-day low (15.12). Resistance starts at SMA20 (20.91), then the recent highs near 25.80 and 28.46. A daily MACD histogram turning positive with a recovery above SMA20 would signal the correction is ending; a break below 16.54 would warn of a deeper pullback within the larger uptrend.

Daily (August 5, 2026)
- Trend
- Bearish short-term within a longer-term uptrend. Price at 19.29 is below SMA20 (20.91, -7.75%) and SMA50 (22.15, -12.90%) after a sharp pullback from the recent high near 28.46, but remains well above SMA200 (12.79, +50.87%). SMA20 and SMA50 have turned down over recent sessions while SMA200 continues to rise, reflecting a fast correction inside a still-strong longer-term advance.
- Momentum
- Bearish. RSI14 at 44.24 is below the 50 midline, indicating weak short-term momentum. The MACD line at -1.01 is below the signal line at -0.87, and the histogram at -0.14 is negative, confirming bearish momentum after the sharp pullback. The MACD values are large relative to price, reflecting the unusually high volatility of recent sessions.
- Volatility
- High. ATR14 at 1.61 equals about 8.33% of price, reflecting sharp daily swings during the correction. Bollinger Bands (16.25 to 25.57) are very wide, and price is trading near the lower band, consistent with a steep short-term decline.
- Volume
- Slightly below average. Latest volume of 15,088,200 is 90.9% of the 20-period average (16,602,770), indicating recent down days have not been met by unusually heavy volume. Volume confirmation remains a watchpoint.
Assessment
The daily chart shows a fast, high-volatility pullback from a powerful rally. Price peaked near the 52-week high at 28.46 and has since fallen sharply, breaking below SMA20 and SMA50 while remaining far above a rising SMA200. The 20-period return of -22.00% illustrates the speed of the correction, while the 252-period return of +188.24% shows the scale of the prior advance. Negative MACD momentum and RSI below 50 suggest the correction may not be finished, but the rising SMA200 and the 52-week position near 58% keep the longer-term picture constructive. The key near-term support is the 20-day low at 16.54.
Weekly (July 27, 2026 week)
- Trend
- Bullish. Price at 19.03 is above SMA20 (17.08, +11.45%), SMA50 (11.68, +62.90%), and SMA200 (7.93, +140.12%). All three weekly SMAs are rising, with SMA200 reflecting the strong longer-term advance of the past year. The 20-week and 60-week highs both sit at the 52-week high of 28.46, confirming the recent peak was a multi-year high.
- Momentum
- Bullish but cooling. RSI14 at 57.48 is above the 50 midline. The MACD line at 3.19 sits just below the signal line at 3.29, and the histogram at -0.10 has turned slightly negative, showing momentum is pulling back after the strong run rather than breaking down.
- Volatility
- Very high. ATR14 at 2.50 equals about 13.12% of price, reflecting extreme weekly ranges during the sharp advance and subsequent correction. Bollinger Bands (5.88 to 28.27) are very wide, and price is trading in the lower half of the range.
- Volume
- Above average. Latest weekly volume of 108,250,700 is 146.6% of the 20-week average (73,851,975), reflecting elevated participation during the recent volatile period.
Assessment
The weekly chart confirms a major uptrend. Price is above all three rising weekly SMAs, and the 20-week, 60-week, and 52-week highs all match at 28.46, showing the recent peak was a multi-year high. The 5-week return of -24.30% reflects a sharp correction off that high, but the 60-week return of +169.85% and the strong SMA alignment keep the weekly trend bullish. RSI at 57.48 remains above the 50 midline, and the slightly negative MACD histogram points to cooling momentum rather than a breakdown. The uptrend stays intact as long as price holds above SMA20 (17.08) on the weekly chart.
