Bottom line
GLW Technical Analysis Summary
GLW presents a mixed technical picture across timeframes. The daily chart shows price trading below SMA20 (201.64) and SMA50 (191.33) with RSI at 45.04 in neutral-bearish territory, suggesting short-term weakness. However, the weekly chart maintains a bullish structure with price above all key moving averages and RSI at 61.04. The stock is trading at the 59.9th percentile of its 52-week range after a significant rally from the 52-week low of 50.77. The SMA200 at 130.18 (daily) serves as major structural support. A sustained move above SMA20 on the daily would signal short-term trend improvement; a break below the 20-day low at 172.75 would indicate further downside risk.

Daily (July 13, 2026)
- Trend
- Mixed. Price at 183.11 trades below SMA20 (201.64) and SMA50 (191.33) but remains well above SMA200 (130.18). The SMA200 slopes upward, confirming a long-term uptrend, while the short-term moving averages suggest a pullback is in progress. The stock has declined from the 20-period high of 271.78 and is testing the lower end of its recent range near the 20-period low of 172.75.
- Momentum
- Bearish. RSI14 at 45.04 is below the 50 midline, indicating bearish bias. MACD at 0.46 with signal at 4.89 and a negative histogram of -4.42 shows bearish momentum with the histogram expanding below zero, suggesting downside pressure is intensifying.
- Volatility
- High. ATR14 at 17.74 (9.69% of price) reflects elevated daily movement, consistent with the recent sharp pullback from highs. Bollinger Bands (155.61 to 247.66) are wide, with price near the lower band, reflecting the recent sell-off.
- Volume
- Below average. Latest volume of 7,584,800 is 44.6% of the 20-period average (16,993,205), indicating reduced participation during the pullback.
Assessment
The daily chart shows a corrective phase following a strong uptrend. Price has pulled back from the 271.78 high and is testing support near the 20-period low of 172.75. RSI below 50 and negative MACD histogram confirm bearish momentum in the near term. The SMA200 at 130.18 provides a major floor well below current price.
Weekly (July 6, 2026 week)
- Trend
- Bullish. Price at 190.89 is above SMA20 (169.66), SMA50 (119.70), and SMA200 (57.13). The SMA200 is sloping firmly upward, reflecting a long-term structural uptrend that began from the 52-week low of 50.77. The wide gap between SMA20 and SMA200 confirms the strength of the multi-year uptrend.
- Momentum
- Bullish. RSI14 at 61.04 is in neutral-bullish territory above the 50 midline. MACD at 23.93 with signal at 23.95 and a histogram near zero (-0.02) shows momentum is flat but remains in positive territory, indicating the weekly uptrend is intact but not accelerating.
- Volatility
- High. ATR14 at 26.96 (14.12% of price) reflects elevated weekly swings. Bollinger Bands (116.49 to 222.83) show price in the upper half of the band, consistent with the bullish weekly structure.
- Volume
- Below average. Weekly volume of 49,089,300 is 72.1% of the 20-week average (68,081,370), indicating modestly lower participation on the weekly timeframe.
Assessment
The weekly chart confirms a strong long-term uptrend. Price has rallied from the 52-week low of 50.77 to the high of 271.78, a gain of over 435%. The current pullback from the high represents a normal correction within a powerful uptrend. The SMA200 at 57.13 provides structural support far below, while the SMA20 at 169.66 is the nearest weekly support level.
