2. I initiate a buy order only if the opening price and day's high price has a difference of a few bucks as the stock has the tendency to fill up the gap. In case an analyst has recommended for a scrip say at a price to buy greater than 100.1 and I observe that the day's high and opening price is say 100.5 or near it , than I donot act on the said tip until and unless the said scrip crosses the day's high with a healthy volume.
3. So, an analyst tip also needs to be traded with brain because as per him the trade should have had been entered at 100.1 but if you do not follow this advice you are likely to burn hands because stock has shown that it has reversed from its resistance level.
