Why did BofA downgrade the stock despite strong third-quarter growth?

  • BofA maintains its forecast for China Merchants Securities' third-quarter 2026 net profit at RMB 7 billion, up 89% year on year but down 5% quarter on quarter. It expects net profit for the first three quarters to rise 98% year on year, leading its peers. The main driver is investment gains on ChangXin Memory Technologies.
  • Looking ahead, BofA expects investment income to face a high base from the same period a year earlier, with earnings growth slowing both year on year and quarter on quarter from the fourth quarter. The contribution from fair-value gains related to ChangXin Memory Technologies will also become less significant from 2027.

Where is the benefit from ChangXin Memory Technologies reflected?

  • China Merchants Securities and its private equity subsidiary together hold approximately 0.7% of ChangXin Memory Technologies' post-money equity. The company marked up the investment's carrying value in the second quarter of 2026 based on its pre-listing valuation.
  • After ChangXin Memory Technologies listed in July, market expectations for China Merchants Securities' related third-quarter fair-value gains rose to RMB 7 billion–10 billion. BofA believes these expectations are largely reflected in the share price: China Merchants Securities' A and H shares have outperformed peers by about 10 percentage points year to date.
  • BofA expects third-quarter trading revenue may fall short of the market's high expectations, while investment businesses outside ChangXin Memory Technologies offer limited incremental growth drivers. It therefore sees a risk of downward revisions to market earnings expectations from 2026.

How much were earnings forecasts and turnover assumptions cut?

  • BofA lowered its forecasts for average daily market turnover in 2026 and 2027 from RMB 2.5 trillion and RMB 2.5 trillion to RMB 2.3 trillion and RMB 2 trillion, respectively. It correspondingly cut its earnings per share forecasts for China Merchants Securities by 2% and 7% for the two years.
  • Under BofA's model, adjusted net profit in 2026 is RMB 18.954 billion, up 61.5% year on year; in 2027, it falls to RMB 14.202 billion, down 25.1% year on year, a decline the bank expects to be the largest among peers. Its earnings forecasts for both 2026 and 2027 are more than 10% below market consensus, and it sees a risk of consensus downgrades after third-quarter results are announced.

How much valuation upside remains, and what could change the assessment?

  • BofA notes that China Merchants Securities' H and A shares trade at approximately 0.7 times and 0.8 times forward price-to-book value, respectively, not far from the industry leaders, leaving limited room for further valuation gains.
  • The bank cut its H-share target price from HK$ 17.50 to HK$ 13.50 and its A-share target price from RMB 19.50 to RMB 15.50. Higher-than-expected turnover and commission rates, and faster-than-expected listings of technology companies, are upside factors for its target prices; falling turnover or commission rates, delays in technology company listings and tighter restrictions on A-share IPOs are downside factors.
