Bottom line
STM Technical Analysis Summary
STM shows a corrective phase within a longer-term uptrend at the August 5, 2026 cutoff. The daily close of 52.77 is below SMA20 (59.43) and SMA50 (67.75) but remains well above the rising SMA200 (42.26), after the stock corrected from the 81.33 high to a 20-day and 60-day low of 47.88. Daily RSI14 at 39.02 is weak but rebounding, and the daily MACD histogram at -0.36 is negative but no longer expanding, with the 5-day return of +9.12% signaling a bounce attempt. The weekly chart remains constructive: price at 52.39 holds above the weekly SMA50 (39.43) and SMA200 (37.16) despite a sharp 26.65% five-week decline, with weekly RSI near the 50 midline. Key support is at 47.88 (20-day and 60-day low) followed by SMA200 at 42.26; resistance stands at SMA20 at 59.43 and the 20-day high at 72.61. A recovery above SMA20 would suggest the correction is ending, while a break below 47.88 would point to a deeper pullback.

Daily (August 5, 2026)
- Trend
- Mixed to corrective. Price at 52.77 is below SMA20 (59.43) and SMA50 (67.75) but remains well above the rising SMA200 (42.26). SMA20 and SMA50 are declining after the sharp correction from the 81.33 high, while SMA200 continues to rise, reflecting a longer-term uptrend that has been interrupted. The 5-period return of +9.12% shows a recent bounce attempt.
- Momentum
- Weak but stabilizing. RSI14 at 39.02 is below the 50 midline, indicating reduced momentum after the selloff, though it has rebounded from oversold territory. MACD at -4.65 is below its signal at -4.30 with a negative histogram of -0.36, still bearish but no longer expanding sharply, suggesting the downside impulse is fading.
- Volatility
- Elevated. ATR14 at 3.78 (7.16% of price) reflects wide daily swings following the sharp correction. Bollinger Bands (43.88 to 74.98) are wide, with price trading in the lower half of the range after testing the lower band during the selloff.
- Volume
- Below average. Latest volume of 9,800,800 is 77.8% of the 20-period average (12,600,940), indicating modest participation in the recent bounce. Higher volume marked the initial decline.
Assessment
The daily chart shows a corrective phase within a broader uptrend. STM peaked near 81.33 and corrected to a 20-day and 60-day low of 47.88, and the recent 5-day bounce of +9.12% has lifted price off that low. Price now sits between the declining SMA20 (59.43) and the rising SMA200 (42.26), which is a key longer-term support. A recovery back above SMA20 would signal the correction may be ending, while a break below 47.88 would target SMA200 at 42.26.
Weekly (July 27, 2026 week)
- Trend
- Mixed. Price at 52.39 is below SMA20 (57.35) but above SMA50 (39.43) and SMA200 (37.16). The longer-term averages remain in a bullish order after the stock more than doubled over the past year, but the sharp five-week decline of 26.65% has broken price below the weekly SMA20.
- Momentum
- Neutral. RSI14 at 48.98 is near the 50 midline, reflecting balanced momentum after a large move. MACD at 7.06 remains above zero but has fallen below its signal at 9.29 with a negative histogram of -2.23, showing momentum fading from the earlier advance.
- Volatility
- High. ATR14 at 7.42 (14.17% of price) shows very wide weekly swings, consistent with the strong rally and subsequent correction. Bollinger Bands (28.16 to 86.55) are extremely wide after the large range expansion.
- Volume
- Above average. Weekly volume of 66,959,400 is 116.6% of the 20-week average (57,421,370), reflecting elevated participation in the volatile move.
Assessment
The weekly chart still reflects an uptrend that has been challenged. STM rallied sharply to 81.33 before correcting over five weeks, and price has stabilized above the weekly SMA50 (39.43) and SMA200 (37.16). RSI near 50 and the MACD line holding above zero suggest the longer-term structure is not broken, but the negative histogram means upside momentum needs to be reclaimed before the correction is confirmed over. A weekly close above SMA20 (57.35) would be a strong signal, while a break below SMA50 (39.43) would raise the risk of a deeper correction.
