A fresh record high yesterday has quickly turned into heavy selling today.
Codan Ltd (ASX: CDA) shares are sinking on Tuesday after registering one of the strongest runs on the ASX over the past year.
At the time of writing, the Codan share price is down 8.40% to $40.23.
That is a heavy fall, but it comes after a huge rally. Codan shares are still up around 41% in 2026 and almost 150% over the past 12 months.
Before today’s sell-off, the stock touched an all-time high of $44.52 on Monday.
So, what changed today?
Major shareholder sells down
The pressure follows an article in The Australian that a block of 8 million Codan shares was sold at $39 per share. That values the sell-down at about $312 million.
The report said the sale was understood to be linked to Pamela Wall, the widow of Codan co-founder Ian Wall.
The sale price was below Codan’s previous close of $43.92, which appears to be the main reason investors are reacting today.
Large block trades often happen at a discount, especially after a strong share price run. But they can still weigh on sentiment, particularly when a stock has just reached record levels.
In this case, the timing looks to be the bigger issue. Codan had been trading at all-time highs, and investors are now taking in a major sell-down from a long-term shareholder.
Why sellers were quick to move
Codan is not falling today because of a weak trading update or a downgrade. The move looks more closely tied to profit-taking after a big rally.
The company designs and sells communications equipment, metal detection products, and related technology. Its products are used across defence, public safety, mining, and recreational markets.
The business has also had strong momentum behind it. Codan has benefited from stronger defence and communications spending, while its metal detection division has been supported by a higher gold price.
Together, that has helped drive the share price much higher over the past year. It has also left the stock trading with far more expectation built in than it had 12 months ago.
Foolish Takeaway
I would not view today’s fall as a sign that the business has suddenly changed.
It looks more like the market reacting to a large discounted share sale after a very strong run.
That said, the size of the recent gain is hard to ignore. Codan has already delivered a huge move, and investors are no longer buying it at beaten-down prices.
From here, I would be watching whether buyers step back in around the $40 level. If they do, the pullback may prove short-lived.
