"Buy akaoa at 1.8c and aka goes to 34c... spectacular 790% return"
Your Maths might be a little out.....
AKAO @ 1.8c......right to buy @ 20c......21.8c break even. 34c-21.8c/21.8c x100
(gives you less return than outright buy now @ 17c).....55.96% Net of brokerage which will reduce your projected return further.
Slightly shy of your spectacular 790%.
