In a fast and furious rally led by a $2 billion buying blitz from foreign institutional investors (FIIs), the Sensex and Nifty have rocketed nearly 8% each over the last six straight sessions of non-stop gains and if Wednesday ends in the green, it will mark a stunning seventh day of this relentless bull charge. With the Sensex sprinting past the psychological milestone of 80,000, and the bulls—now visibly giddy—are placing their bets on the Nifty storming toward 25,000.
