It did occur to me that the SP may gravitate back to $1.60ish before the rights are even dished out.
This (as you suggest) could be a nice way for Fosters to pick up a stake and it may even serve to suppress the price of the rights - a few buyers might like the idea of picking them up for a few cents a pop.
It's going to be interesting to see how this unfolds, given the trading pattern of the last three months I'm not expecting the SP to remain bullish at this time.
