Bottom line

ONTO Technical Analysis Summary

ONTO (Onto Innovation) presents a mixed technical picture after a sharp pullback from its 52-week high. The stock surged from near 89 to a high of 386.46 over the past year, then fell about 44 percent to a late-July low of 215.07 before bouncing to 268.70. On the daily chart, price at 268.70 trades below SMA20 (279.02) and SMA50 (293.72) but above the rising SMA200 (223.97), leaving the short-term trend unresolved within a longer-term uptrend. RSI14 at 46.71 sits just below the 50 midline, and the MACD histogram has turned positive at 0.82 even though the MACD line remains below its signal line, an early sign that downward momentum is easing. The weekly chart remains constructive, with price at 258.58 above the rising SMA50 (205.08) and SMA200 (154.92) but below SMA20 (276.02), and the weekly MACD histogram is negative. Key resistance sits at 279.02 (SMA20), 293.72 (SMA50), and 327.50 (20-day high). Key support rests at 215.07 (20 and 60 day low) with the rising SMA200 at 223.97 acting as near-term dynamic support. A sustained move back above the 279 to 294 zone would begin repairing the short-term trend, while a break below 215.07 would signal a deeper correction.

Daily (August 6, 2026)

Trend
Mixed, short-term pullback within a longer-term uptrend. Price at 268.70 is below SMA20 (279.02, -3.70%) and SMA50 (293.72, -8.52%) but above the rising SMA200 (223.97, +19.97%). SMA20 is sloping down after the correction while SMA50 has flattened and SMA200 continues to rise, so the short-term trend is not yet repaired.
Momentum
Neutral. RSI14 at 46.71 sits just below the 50 midline, reflecting a loss of upside momentum after the drop from the 386.46 high. MACD at -9.81 is below its signal at -10.63, but the histogram at +0.82 has turned positive, indicating that downward momentum is easing and the two lines are converging.
Volatility
Elevated. ATR14 at 25.08 (9.34% of price) reflects large daily swings during the correction. Bollinger Bands (229.10 to 328.93) are wide, and price at 268.70 trades below the middle band at 279.02, in the lower half of the range.
Volume
Above average. Latest volume of 1,580,955 is 139.2% of the 20-period average (1,135,968), showing elevated participation during the volatile correction and the subsequent rebound.

Assessment

The daily chart shows a sharp correction inside a longer-term uptrend. ONTO fell from the 52-week high of 386.46 to an intraday low of 215.07 in late July, then rebounded more than 20 percent to a closing high of 287.60 on August 4 before easing back to 268.70. Price has reclaimed a portion of the decline but remains below SMA20 and SMA50, so the short-term trend is still uncertain. The positive MACD histogram is the first stabilizing signal, while RSI below 50 argues for caution. A sustained move back above SMA20 at 279.02 and then SMA50 at 293.72 would repair the short-term trend; a break below the 215.07 low would point to a deeper correction toward the weekly SMA50 near 205.

Weekly (July 27, 2026 week)

Trend
Mixed but constructive. Price at 258.58 for the week of July 27 is below SMA20 (276.02, -6.32%) but above the rising SMA50 (205.08, +26.09%) and SMA200 (154.92, +66.91%). All three weekly averages continue to slope upward, and the pullback has so far held above the SMA50, leaving the longer-term uptrend intact.
Momentum
Fading. RSI14 at 50.20 sits right at the 50 midline after the powerful advance. MACD at 23.60 has moved below its signal at 30.19 with a negative histogram of -6.59, confirming that weekly upside momentum has rolled over from the peak.
Volatility
High. ATR14 at 42.20 (16.32% of price) reflects very large weekly swings, consistent with the recent round trip from the high. Bollinger Bands (200.04 to 352.00) are extremely wide, and price is below the middle band at 276.02.
Volume
Above average. Latest weekly volume of 7,465,100 is 136.0% of the 20-week average (5,489,050), indicating strong participation during the pullback.

Assessment

The weekly chart still reflects a strong uptrend that started from the 52-week low near 89.40. Price remains above the rising SMA50 and SMA200, and the pullback has not violated the longer-term structure. However, price has slipped below SMA20, RSI has fallen to the 50 midline, and the negative MACD histogram shows fading upside momentum after the peak near 386.46. The uptrend stays intact as long as price holds above the weekly SMA50 near 205; the key downside reference is the 20-week low at 188.28.
