I bought this SFL and BLI when its at garbage. This runs were backed by broker firms. BLI tried best to lure the main holder to sell or come to a consolidation, but all went wasted. Now i saw some of them say it gonna buy at over 30Rs. But who will sell? That guy is a hard chap, so he wont do it most probably.
The selling and volume you see is coming from BLI accounts, they were in the selling side from few months before. May be its another plan of them.
Finally i have to say is, dont keep high hopes.
