Characteristics of human(Mental tug of war)

$SIA (C6L.SG)$ When we select SIA. we all know and prepared for long war. When SIA make some progress, people sell for few cents gains. Maybe they have millions of dollars invested. So the few cents gains to them is alot. when they sell it makes market down retail investor become scared and sell and makes things worse. When ppl sell u dun sell and it dropped, you said missed the boat. And finally u have a chance to sell and u sold, the market moved and u will say u missed the boat again. Make a decision and stick to it . We are not invested to gain small . we trust the company growth.
