The psychological mark of 22,000 holds intermediate support, followed by strong support of the 21,800-21,700 subzone. On the higher end, the 20-DEMA placed at 22,300, followed by a bearish gap of 22,430-22,500, is likely to act as a daunting task in the near period and an authoritative breakthrough could only re-strengthen the lost momentum to the bulls of D-Street, said Osho Krishan of Angel One.
