The reactions to IG Group’s Q3 trading update keep on coming.

After earlier today rival online broker Plus500 (LON:PLUS) issued a surprise mid-day trading update of its own, indicating that IG Group’s apparent troubles were not “spilling over” into its results, another competitor, CMC Markets (LON:CMCX), has issued a statement of its own.

The day began Friday with IG releasing its Q3 2026 Trading Update, which contained disappointing results including declining revenues. When trading began (at 8:00am UK time), IG shares promptly fell by more than 20% to a new 52 week low. The negative action also dragged down the shares of Plus500, CMC, and XTB SA (WSE:XTB).

Plus500 – which had seen its shares decline by about 14% early Friday – then promptly (around 10:00am) issued its own statement that its results remain in line with previously communicated expectations. Plus500 shares promptly recovered, and are now down about 5% on the day.

Now CMC Markets has issued a press release (full text below) that its CEO and controlling shareholder, Lord Peter Cruddas, had purchased during the day 23,011 shares of the company in the open market for total consideration of approximately £139,000, i.e. at about £6.04 per share.

And, that Lord Cruddas intends to purchase more shares (without giving a specific time frame) worth up to £5 million, including the purchase announced today.

The statement did seem to somewhat buoy CMC stock, which was down about 9% on the day when the statement was released, and is now off about 6%.

We’d note that CMC has a market capitalization of more than £1.7 billion, and Lord Cruddas owns more than 60% of that, such that £5 million isn’t that meaningful a figure in the grand scheme of things. However, as per above, his commitment to buy more shares seems to have (somewhat) calmed the market in CMC stock.

The CMC Markets statement reads as follows:

CMC Markets CEO Share Purchase and Intention to Purchase Further Shares

CMC Markets (“CMC”), a FTSE 250 company and global multi-asset financial services firm, announces that Lord Peter Cruddas, Chief Executive Officer of the Company, has today purchased 23,011 ordinary shares in the Company (“Ordinary Shares”) for an aggregate consideration of approximately £139,000.

Lord Cruddas has also informed the Board that he currently intends to purchase further Ordinary Shares at market with an aggregate value of up to £5 million including the purchase announced today.

Commenting on the purchase, Lord Peter Cruddas, Founder and Chief Executive Officer, CMC Markets, said: “As founder and long-term CEO, I am adding more shares to my investment in the company. Since our IPO in 2016, I have never sold any of my shares in CMC Markets and I intend to make further investments in the near term.”

Any such purchases would be undertaken for Lord Cruddas’ own account and represent his personal investment decision.

The purchases will be subject at all times to applicable legal and regulatory requirements, receiving appropriate dealing clearances under the Company’s share dealing code and prevailing market conditions.

There is no commitment to purchase any particular number of Ordinary Shares and there can be no certainty as to the timing, price or extent of any purchases.

All share purchases will be subject to the usual regulatory and market disclosure requirements.
