Meanwhile, please beware of abnormally high premiums on both sides of Banknifty options. As per my experience, this normally happens just a week before Budget. As soon as Finance Minister's Budget speech would get over, all the extra premium would be gone with the wind. Then only market decides which way to go. The same thing happens just before every RBI monetary policy event day. This is nothing but meaningless buying of both PE & CE and also over speculation. Watch closely!!
