It strikes me that SGH only has 8.25% of its stock shorted and it's number 22 on the top 100 shorted stocks. So if those negative are so convinced that SGH is a dead dog then why have the shorts been decreasing and not pushing up towards the 20% mark in that case????? I would have thought the shorts would have been increasing as we got closer to the half year results if so many people believe this company is at risk of going belly up or am I missing something here? Could someone who is sensible and has a sell sentiment on SGH please explain to me why the shorts have reduced and not increased, I'd be interested in your take on this aspect of the market mechanics in regards to this fascinating stock-cheers, not looking for arguments just opinions, because this bit isn't making sense to me. Is this saying that the shorts are less convinced about their collective negative sentiment?
