With global markets closing on a weaker note on friday, we can decently expect a weak opening of Asian markets on monday.
Nifty could retreat as far as 4933, 4890 or 4833 is respected. There may be bounce from either of these levels. If 4833 is breached, we may expect further weakness & then next target would be 4538. Key resistance this week will be 5083 & 5162.
