RE:With Ird performing well it’s time to up the dividendI would prefer that they NOT raise the dividend. Quarterhill is the kind of tech story that typically pays no dividend at all.
If they're having trouble coming up with (or closing on) compelling acquisition candidates I would argue for them resuming the share buyback. If you believe the shares are fundamentally undervalued then you should prefer share buybacks to dividends because each time the company buys back (and then cancels) shares it will raise the intrinsic value of each remaining share.
If you don't believe the shares are fundamentally undervalued then I suppose you should sell your shares.
