Why is everyone buying Macquarie Group shares this week?
There isn't any price-sensitive news out of the ASX bank stock to explain the latest increase. Instead, it looks like a mixture of recent tailwinds and improving market sentiment.
Through most of the year so far, the investment bank has performed strongly, rallying strongly in April and sitting close to today's all-time high.
In late July, the company had its AGM, posted its first-quarter FY27 update, and announced that CEO Shemara Wikramanayake will retire in November, with Greg Ward to take over the top job.
Macquarie described trading conditions during the first quarter as "satisfactory". Its Banking and Financial Services segment increased its profit contribution compared with the same period last year. Deposits rose by 4% during the quarter, while home loans grew by 6% and business banking loans increased by 3%.
The news came on the back of the company's positive earnings results back in May. At the time, Macquarie reported a full-year FY26 net profit of $4.85 billion, up 30% from FY25, and growth across all four of its operating divisions.
The rally of good news has clearly been well-received by the market. Analysts have begun revising their outlook on the shares, and investors have started snapping up the stock ahead of an expected surge.
What do the experts tip for Macquarie's shares over the next 12 months?
