No, it's not laughable. There are lots of other stocks out there. YOU may feel that AGSS is better than others, but not everyone agrees (for the record I am holding on to my AGSS shares).
For someone who does not feel more strongly about AGSS than other stocks, selling to capture the tax loss makes perfect sense. For them, the decision is "do I want $1000 worth of stock A" or do I want $1000 worth of stock B and a tax loss" . If you think the stocks have equal potential than obviously it makes sense to sell A at a loss and move to B.
While I am not selling AGSS now, I do this every December - sell some losers and buy something else that now looks to have better prospects.
