There are other consumer discretionary related shares that rose well on good news recently and then lost most of their gains - EDV, MOZ, even ZIP which is falling through the floor right now. A lot of the big boys are short term IB and hedge fund traders looking to buy in and sell quickly on announcements. There will be this sort of thing until the current issues subside and SGR returns to profitability, dividends etc. However at least the company's future looks more secure.

I don't think sentiment has changed too much with SGR since the casino tax announcement but as I said back then there are still uncertainties to make the share price volatile I.e. the fear of declining retail and hospitality spending.
