The yellow zone on the chart is where CPV been traded most of its history since listing (too wide a zone!).

So 24c or so seems quite deep in that support zone; and one may offer a reversal (as a side note CPV options are also 25c). CPV proposed commercialisation in Feb 2019 (so may be also a built up for that). 

Watching intraday trade in the past few sessions, I think there was good interest at 24c price point (in particular off-screen buys). Of course, all within the limits of CPV low daily volume.

So I think we should see a reversal from there / or at least a decent trade. How big is the reversal is another question of course (say a 20% trade or a sustained change of trade?). 

Of course we don't want CPV to go below support zone (in a meaningful way and not a spike).

All IMHO, and I could very well be wrong.
