My position has always been don't invest (and that's all stocks in the present climate) what you cannot afford to lose. BBI for me is a long term proposal (therefore not a short term money making scheme)which requires certain events (asset sales) to occur to achieve a re-rating (therefore a substantial risk/ reward play).
Unfortunately only asset sales seem to be the trigger to move this share upwards, as I cannot see a quick resolution to the GFC. Asset sales will not happen overnight.
I wouldn't even pretend to offer advice or preach, however when I saved for my deposit not one cent of the money was in shares. I only play with the money free after the mortgage, bills and rainy day fund. This is not to say BBI won't shoot up on good news, however that is the risk you take in this present market and further risk it does not occur in your short time frame. All current indicators on lack of news on asset sales is downward, along with the general market.
IMO it is bestest to have a serious think, sort your proirities, risk tolerance and investment time frame and I am sure you will come to an answer that best suits your own circumstances.
Cheers
