We will have to wait until to morrow to get the
total short figure from the ASX but Friday is often when positions are predominantly closed so if the gross shorts (reported volountarily , so not always accurate) were mainly buying then I am
guessing that the percentage reported will go down down to circa 10.5% although the rporting may not trickle through fully until Monday.
If I was shorting GXL and I saw the level of holder buying support on Friday I would definitely be a bit spooked and taking some profit of around 10%. The gross shorts Mon-Wed have been modest but given the positive jump today I suspect there may be more plus a squeeze tomorrow as more positions close.
The short position opened in May around the 4.50-4.50 mark will not want the SP to get much above 4.1--4.15 as the percentage will start to not be worth it. If the SP gets above 4.10 tomorrow it will be interesting...
All the above musings are IMHO. I am still learning about how the short game is played.
