You're a big company and you buy a few million shares of a company that looks like it has prospects when it's only pennies a share. One day it takes off and then when the fervour subsides a bit and people are waiting for something more, you start to sell it down all the while still making a tidy profit and setting the situation so that you can now go in and buy some serious shares at a much reduced price, when you now decide that the risk is reduced, when you know there will be time within which to accomplish this. This is a pattern that seems to be ubiquitous in the market and there is a certain favoured gold company amongst posters here that seems to fit this framework over the last few days in particular. I dare say that NOT could well be seen in this scenario. :)
