When the ratios get to where the were today my strategy would be BUY, BUY, BUY. Buying pressure would have meant an increase in the SP. Today saw an increase in EDE which was not mirrored in TAS. This also strengthens my argument that TAS lags EDE in most SP change. Maybe that is the answer. If I have it right there should be a cent or two due for TAS. I'm light EDE and heavy TAS so I'll not be trading again tomorrow. I therefore wont be adding buying pressure. I'm waiting for a chance to sell TAS and buy back EDE. I'm looking for and needing 1.2 to 1 again.
One day........ One day I expect it to change. The trigger for change will be tied to where the TAS activities will be directed when they have funds available independent of the book value shown as cash on hand that really is Eden's cash and not cash that TAS has available.

There was a time when TAS was the big daddy and EDE the adolescent child. The child grew up, went to uni (Monash), graduated and is now has the prospects of out earning the parent.
