Bottom line
ROK Technical Analysis Summary
ROK shows a mixed daily chart that turned sharply lower after the August 4, 2026 selloff. The daily close at 445.23 sits below SMA20 (465.21) and SMA50 (464.64) but above SMA200 (410.94). The -7.43% one-day drop closed below the lower Bollinger Band on volume at 2.64x the 20-session average, pushing RSI14 to 41.48 with a negative MACD histogram of -0.70. The weekly picture is still bullish through the July 31 close, with price at 480.08 above all major averages and RSI at 68.52, but that series does not yet include the August 4 decline. The near-term bias is defensive: support sits at the 20-day low at 433.21, then the 60-day low at 418.84 and SMA200 near 410.94. Resistance is the former support cluster near 465 and the 20-day high at 489.35. A reclaim of the 465 area would restore the daily uptrend, while a close below 433.21 would open the door to 418.84.

Daily (August 4, 2026)
- Trend
- Mixed with a bearish tilt. The August 4 close at 445.23 is below SMA20 (465.21) and SMA50 (464.64) but above SMA200 (410.94). The sharp one-day decline broke the medium-term structure, and SMA20 and SMA50 have flattened near 465 after the drop. SMA200 continues to slope upward and provides the major long-term support.
- Momentum
- Neutral to bearish. RSI14 at 41.48 is below the 50 midline but not in oversold territory. MACD at 0.45 is below its 1.15 signal with a negative histogram of -0.70, indicating momentum turned down after the selloff.
- Volatility
- Elevated. ATR14 at 17.31, or 3.89% of price, reflects the wider daily ranges from the move. Bollinger Bands span 449.55 to 480.88, and the close at 445.23 sits below the lower band, showing a volatility expansion on the decline.
- Volume
- Well above average. August 4 volume of 2,136,822 shares was 2.64x the 20-session average of 809,921, reflecting heavy participation on the down day.
Assessment
The daily chart suffered a sharp one-day decline on August 4 on heavy volume, closing below SMA20, SMA50, and the lower Bollinger Band. RSI at 41.48 is neutral to weak and the MACD histogram is negative. The key near-term support is the 20-day low at 433.21, which was the intraday low of the selloff, followed by the 60-day low at 418.84 and SMA200 near 410.94. Resistance is the former support cluster around 465 (SMA20/SMA50), then the 20-day high at 489.35.
Weekly (July 27, 2026 week)
- Trend
- Bullish. The completed weekly close at 480.08 is above SMA20 (434.57), SMA50 (399.44), and SMA200 (304.96). The averages are in bullish alignment, and SMA200 is sloping upward, confirming the longer-term uptrend through the July 31 close.
- Momentum
- Bullish but stretched. Weekly RSI14 at 68.52 is approaching the conventional 70 overbought threshold. MACD at 23.77 is above its 22.50 signal with a positive histogram of 1.27, confirming positive longer-term momentum.
- Volatility
- Moderate. ATR14 is 26.45, or 5.51% of the weekly close. Bollinger Bands span 352.02 to 517.13, with the close in the upper part of the range.
- Volume
- Near average. Weekly volume of 3,792,600 shares was 0.99x the 20-week average of 3,816,620, showing normal participation through the latest completed week.
Assessment
The weekly timeframe remains structurally bullish through the week ending July 31, with price above all major averages and a positive MACD histogram. RSI at 68.52 is approaching overbought, so the uptrend is stretched. The key caveat is that this weekly series ends July 31 and does not yet include the August 4 selloff, so the bullish weekly signal should be read with additional caution until the current week completes.
