I don't know if they should stop, maybe ? But they need to at least get better at it and stop if they can't. Being more realistic would also be good.
But to many times these kind of companies (companies needing money) are giving guidance that seems to be more to promote and pump before going to the markets for money than be a realistic representation of what they expect.
Shortly after mako gave guidance earlier this year they arrange 50m on financing. Would that financing have been at a higher interest rate or required more warrants to sweeten the deal if guidance had reflected reality ?
