yes, lots of new posters, becuase we see some developments. So one poster asked - should we take some profits ? always good to lock in gains, but as the lady said, why not wait for winter to have a seasonal affect driving the price up ? Also, NVS is not a speculative stock - it has real, hard assets, and huge growth potential.
So all strategies are good - sell in stages on the way up, sell on bounces and buy back on dips, or hold for the long term - all will be good with NVS - just a matter of preference and how long you have been waiting.
