I have a problem with it, too, ST. The buying by PC and Suresh was surely orchestrated amongst management, there was no coincidence there. I would not at all be surprised to see that Ajit and Subhash are also about to buy some shares - rather than have it done all at once, they are piecemealing it for cumulative effect, which I think is smart.
No need for the "big investor" to use such tactics. Management seems to have this under control and I think we ALL agree now that we're in good hands. There was legitimate disagreement on that point until the Suresh and Subhash joined.
