China’s two main stock exchanges have vowed to tighten supervision of quantitative trading after freezing the accounts of a major fund for three days, as part of wider regulatory efforts to revive market confidence.

The Shenzhen and Shanghai stock exchanges Tuesday said major quant fund Lingjun Investment had broken rules on orderly trading and barred it from buying and selling for three days.
