don't you wonder why?

Don't you sometimes wonder why sharetraders do what they do? For instance, why sell BSM today at 34.5 or 35c? I can't see a lot of sense in selling out permanently at all at the moment, with a good rise not too distant. Sure it makes good sense to sell on a spike with the intention of buying back in a little lower, but that spike occurred last week at 38c. On balance it would seem a big risk selling at today's price and hoping to achieve that outcome. At any time the company could put out an operations update that sounds very positive; perhaps decline completed, ore encountered, raise boring completed, mill refurbishment completed, etc. Additionally, it may not be too long before a positive Fossey East drilling report emerges. Any of these things should have a positive effect on the SP. So why would you sell today? Often I think many traders are only scantily acquainted with exactly what is happening at any point in time at their company. My best guess is that sellers on a day like today are short term traders who bought in a few days ago to make a quick quid without really understanding the company at all, and who are now looking to move on to another stock that's on the rise. Any thoughts?
