Shares widened their losses on the afternoon of July 31 as blue chips fell on rising precaution about the market outlook.

Blue chips led the downturn as banks, insurers, oil and gas shares - market drivers in previous rallies - all tumbled. 

Vietcombank (VCB), the biggest stock in terms of market value, dropped 2.2 percent while other banks like Military Bank (MBB), Eximbank (EIB), Vietinbank (CTG) and BIDV (BID) lost between 0.6-1.5 percent in value.
