Aban etc have small market cap. So this is a line wasted in its discussion.
Lets only consider the big boys like, Ril, Infy, ITC, HuL that have status in Nifty.
After factoring in the split/bonuses, the all time high of Reliance Industries is 1626. Its CMP of 905 so that is a relief enough for the desperate. And every further inch up will tempt them more... unless the bullish momentum is strong... that was my point.
Now let us not consider the buyers of 2008 only. Because any and all buyers have their own perspectives and if their net sentiment is bearish then increasing price will attract sellers. Sure, if its bullish then they will buy... but I highly doubt any major investment is gonna come in now given the instability due to the elections next year.
Then again, you never know.
