Aon closed at $272.10 on September 28, a fresh 52-week low set just four sessions after the last one, and the pace of new lows is itself the signal.
From its 52-week peak of $376.30 reached in May, Aon has now shed roughly 28%. That kind of drawdown from a high is unusual for a large, established insurance broker, a sector that typically attracts investors looking for stability and steady earnings rather than volatility.
The most recent leg down accelerated sharply, carrying the stock through the $300 level it defended all summer in a matter of weeks.
For investors already holding the shares, the relevant question is whether the current price represents a durable floor or simply the latest step in a continuing decline. Until the stock can establish even a short-term base and stop making new lows, the technical picture offers little comfort.
