HDFC is showing a possible mild bounce back on the 5 and 15 Minute Chart, the bounce back can take the stock to near around 1965-70. Stop loss should be below 1840 as that's the previous bottom and breaking this decisively would mean another 10 rs break down on the least.
Hourly chart shows mild double top formation at 932 formed on 6th March, little weakness in nifty can drag it down to 925-926 levels. Stop loss should be 938 breaking which would confirm a further upward movement.
