Ann: Results of BARD1 Ovarian Cancer Study, page-76

My feeling is because the price only moves on positive news. Looking at plans for 2018 in the AGM slides there's very little potential significant news (technical validation test results) on the radar until at least 2H 2018. Thats a long time to just have capital tied up for some. Once this buying frenzy abates the stock will most probably languish again with very little volume within a tight band (as it has since May last year) and slowly lose value as people pull money out for other reasons. People who are long termers are getting out now while the getting is good, securing a decent profit if they bought during the cap raising, or accepting a loss just to get rid of the shares if they bought higher, safe in the knowledge that if they really want to they're able to get back in later at a lower price. The only risk is an unexpected announcement in the interim that triggers a run.

This is my opinion only. As always DYOR.
