As far as I am aware, no big boys were holding SGH shares until recently. I have seen the top 20 list a few months ago, and even those who owns mere 1 million shares were in the list. My feeling is that big boys have started buying since yesterday. Most of the retail sellers are gone now and I expect the price to rise dramatically tomorrow.
