Nov 20 (Reuters) - Shares of CMC Markets CMCX.L rose over 20% on Thursday after the British trading platform forecast net operating income above market expectations, following robust first-half performance across its retail and business-to-business divisions.
The company said it expects its fiscal year 2026 net operating income to be about 10% ahead of current market estimates of 353.9 million pounds ($462.2 million), according to a company-compiled consensus.
CMC said its partnership with Australian lender Westpac WBC.AX, due to launch in about 12 months, is expected to materially expand its customer base and lift domestic trading volumes by around 45%, taking its retail footprint close to two million accounts within a year.
The firm, which offers trading in more than 12,000 financial instruments, is also exploring partnerships with blockchain firms and crypto exchanges as decentralised finance evolves.
Its net operating income rose 5% to 186.2 million pounds for the six months ended September 30, ahead of market consensus.
The stock was the top gainer on the FTSE mid-caps index .FTMC, which was up 0.44% at 0834 GMT.
