Bottom line
AON Technical Analysis Summary
AON (Aon plc) is in a short-term pullback within a broader weekly recovery. On the daily chart, price at 356.65 has fallen below SMA20 (361.57) after a -6.24% five-day decline, with RSI at 50.98 and a negative MACD histogram of -1.89, pointing to faded short-term momentum. The weekly chart is more constructive: price at 359.73 sits above SMA20 (330.22), SMA50 (340.20) and SMA200 (329.10), the MACD histogram is positive at 5.80, and weekly volume is running 1.48 times its 20-week average. Key daily support is SMA50 at 341.23 and the 20-day low near 349.66, while resistance stands at 381.47, the 20-day high that also marks the 52-week high. The stock trades at 68.33% of its 52-week range on the daily chart. A stabilisation above SMA20 would signal the pullback has ended; a close below SMA50 would open a deeper correction.

Daily (August 4, 2026)
- Trend
- Mixed. Price at 356.65 has pulled back below SMA20 (361.57, -1.36%) after a sharp five-day decline of -6.24%, but remains above SMA50 (341.23, +4.52%) and SMA200 (335.20, +6.40%). The medium-term averages are still stacked below price, so the broader recovery from the 60-day low near 307.81 remains intact even though short-term momentum has cooled.
- Momentum
- Neutral turning lower. RSI14 at 50.98 sits near the midpoint, showing neither overbought nor oversold stress after the pullback. MACD line at 5.92 has moved below the signal line at 7.81, producing a negative histogram of -1.89. This reflects fading momentum following the prior advance and warns that the short-term corrective phase may continue.
- Volatility
- Moderate. ATR14 at 10.02 (2.81% of price) reflects a typical daily range of about 2.8%. Bollinger Bands span 347.01 to 376.12, with price trading in the lower half of the band after the pullback. The band is wide relative to the 60-day range, consistent with the elevated swings seen in recent weeks.
- Volume
- Below average. Latest volume of 757,320 is 53.8% of the 20-period average of 1,408,041, indicating low participation during the pullback. Volume coverage can differ by venue, so the reading is approximate.
Assessment
The daily chart shows a short-term pullback within a longer recovery. Price has retreated below SMA20 while RSI has cooled to neutral and the MACD histogram has turned negative. Support sits at SMA50 (341.23) and the 20-day low near 349.66, with stronger support near the 60-day low at 307.81. Resistance is at the 20-day high of 381.47. The 68.33% 52-week position leaves room on both sides. A stabilisation above SMA20 with rising volume would signal the pullback is over; a close below SMA50 would open the path toward deeper support.
Weekly (July 27, 2026 week)
- Trend
- Mixed with positive bias. Price at 359.73 is above SMA20 (330.22, +8.94%), SMA50 (340.20, +5.74%) and SMA200 (329.10, +9.31%). The SMA50 sits above SMA20 and SMA200, reflecting a medium-term uptrend that price re-entered after a mid-year dip. The 5-week return of +9.69% and 20-week return of +12.47% confirm the recovery, while the 60-week return of -2.38% shows the intermediate stretch has been uneven.
- Momentum
- Neutral with bullish MACD. RSI14 at 59.06 is in neutral territory, leaving room for the trend to continue without overbought stress. MACD line at 6.08 is above the signal line at 0.29, with a positive histogram of 5.80. The widening positive histogram suggests medium-term momentum is building.
- Volatility
- Elevated. ATR14 at 19.27 (5.36% of price) reflects wider than average weekly ranges. Bollinger Bands span 293.42 to 367.01, and price is trading below the upper band after the recent advance, leaving some headroom before a statistically stretched reading.
- Volume
- Above average. Latest weekly volume of 10,652,400 is 1.48 times the 20-week average of 7,204,515, indicating strong participation during the recent advance. Volume coverage can differ by venue, so the reading is approximate.
Assessment
The weekly chart shows a constructive recovery. Price is back above all three moving averages, the MACD has printed a bullish crossover with a rising histogram, and volume confirms the move. The main caution is that the 60-week return is still slightly negative and price sits near the upper end of its 20-week range, so this reads as a recovery rather than a mature uptrend. A sustained weekly close above the 20-week high of 381.47 would extend the breakout; a drop back below SMA20 (330.22) would put the recovery at risk.
