SGH is definitely a mum and dad's stock, haven't been any institutional holders in the registry for around a year now. There's a few brokerage firms trading on the ebbs and flow, but its small-time stuff.
That's why I'm always dubious when I hear a bull say 'X event has already been factored in to the SP by the market'. The 'market' in this case are taxi drivers, factory workers, bored retirees and stay-at-home mums. They are not sophisticated or technically adept investors. They're far more likely to under-react / over-react, and be blindsided and wrong footed by market and company developments.
Btw, SGH is currently only the 31st most shorted stock on the ASX (shorts as a proportion of total shares): http://www.shortman.com.au/top
