Fine, let's make it a longer timeframe then, pick one of no more than a 18 months possibly though, some are long in the tooth here and the second law of thermodynamics has been tested.
I like to suggest a greater-than percentage of 33, so that a >33% increase on Friday's closing price of 5.3c would correspond in 9 months time to a sp above 7.1c.
A >33% decrease in the sp would correspond to a sp below 3.5c.
If you like the odds than we have a bet and we shall both agree that, in the event of the sp recording a >33% movement by the end of the timeframe, one of us will start a thread titled "I was wrong on ALGAE.TEC".
