Take a look at the pattern at Aben Resources. It's always similar but to varying strengths.
In the Canadian taxloss season, the Canadians sell everything that is not nailed down and then buy it back in the new year. If good drilling results have been presented, the share price has risen by 300, 500 or even over 600 percent. If no noteworthy drilling results were presented, then it was "only" a good 100 percent.
I don't know if it will work again this year with CEO James Pettit, but it's good to know that it worked in the last years ;-)
