I don't see GXY going lower any further. It must re-rate pretty soon and it's stock prIce should be at least $3.5 - $4.0 IMHO.
At $2.5 the company valuation is $1 billion. As soon as SDV sale settles half of this valuation will be represented by the cash on the books. Secondly we will also book $50m for 2H2018 and $150m for FY2019. That means by Dec 31, 2019 we will have $700m in cash.
The $150m profit after tax estimate for Dec 31, 2019 also translates into a forward looking PE estimate of 6.8x for GXY. In comparison S&P 500 PE forward estImate for Dec 31, 2019 is 17.3x.
