Key Takeaways:

MarketAxess Holdings Inc. facilitated $1.04 trillion in Q2 credit trading volume, up 1% from a year earlier, while total average daily volume fell 11%.
"We continued to make progress with block trading, portfolio trading and dealer-initiated protocols across the platform," the company said in its July 7 release, citing record levels in portfolio trading and Mid-X volumes.
Total credit ADV excluding single-dealer portfolio trading came in at $16.95 billion, down 10% year over year. U.S. high-grade estimated market share reached 17.9% in June, up about 10 basis points, while high-yield share rose 190 basis points to 14.9%. Adjusting for duplicate trade reports that the company estimates inflated TRACE volumes by up to 8%, adjusted high-grade market share would have been approximately 19.4%.
The Zacks consensus estimate calls for Q2 earnings of $1.90 per share, a 5% decline from a year ago, on revenue of $220.43 million. MarketAxess has beaten earnings estimates in each of the past four quarters, with an average surprise of 4.5%.
Portfolio Trading Drives Growth
Total portfolio trading ADV rose 33% to a record $2 billion, with U.S. high-grade ADV of $1.2 billion up 41% and U.S. high-yield ADV of $459 million up 93%. The company's estimated market share of U.S. credit portfolio trading reached 20.6%, up from 17.5% a year ago.
Client-initiated block trading ADV increased 11% to $5.9 billion, with U.S. credit block ADV of $3.4 billion up 8%. Emerging markets block ADV of $2 billion rose 24%, while eurobonds block ADV of $503 million declined 5%.
Dealer-initiated ADV fell 3% to $1.7 billion, with record levels in eurobonds, municipal bonds and emerging markets partially offset by declines in U.S. high-grade and high-yield. Total Mid-X trading volume hit a record $23.6 billion, surging 156%.
Fee Trends and Market Share
Total credit average variable transaction fees per million declined 7% year over year to $127, driven by protocol mix, product mix and lower duration in U.S. high-grade bonds. Total rates FPM rose 24% to $4.88, driven by protocol mix.
The company's estimated U.S. high-grade market share on an all-in basis was 17.9% in June, while high-yield share reached 14.9%. Municipal bonds market share stood at 6.9%, and U.S. government bonds share was 2%.
The strong portfolio trading and block trading performance signals that MarketAxess is capturing a larger share of institutional flow even as overall industry ADV declines. Investors will watch the official Q2 earnings release for updated guidance on fee trends and market share trajectory.
