It's not a bad idea to repurchase shares especially since we all believe POET is undervalued. Most often companies buy shares back at the wrong time.
The problem is we don't have the cash. If the cash was available for share repurchase we wouldn't be staring at this 30 cent share price. I for one hope the company has better value creation opportunities to spend on. Preferably they go after the verticals that get us revenue 'soon' and keep expanding the portfolio as cash comes in.
