IVA can double and halve quickly, and has done so a few times in the past 6 months, from the HC graph. Back down to the capital raising price. It is always one to watch due to the massive swings, and as you both have said, when she rises, she does so with great gusto (can fall like that, too!)
Good luck, holders. Many watch IVA- a good trading share when it is at its lows.
