Analysts recommend a selective buy-on-dips approach as long as the Nifty index holds above key support levels. Sudeep Shah, of SBI Securities, said the 22,800-22,850 zone would be a crucial support area for the index. A decisive break below 22,800 could intensify selling pressure and drag the Nifty towards. The 22,800-22,900 range is expected to act as a crucial support zone.
