Frankly, no one hope to loss their investment... aww, who don't want to earn more? Somehow, trading in stock exchange does not guarantee profits but in fact, you may loss more than earn sometimes. The market can be so cruel and they don't care who you are or how new you are... haha... all about they care is of course $$$(Money). We may get ourself hit until bleed if we didn't learn some tactics to protect ourself. One of the tricks is to not to loss more than your preferred loss comfort level and doing so we can still protect our capital. Think those pro named it "Cut loss" but I called it "stop bleed and come back later" hahaha... Tell you, this is not funny but this is really helpful. Me experienced numerous times of cut loss and then able to join back at lower price to enjoy the rebound(sometimes bro, i meant sometimes)! By the way, my cut loss point was around 15% initially(I was a long term investor) and slowly became 10% then now preferred at 8-10%. I know is crucial for some people watching your portfolio valued lesser and lesser but, if you still locking your capital in and kept yourself watching only will only make yourself feel more painful. Of course, most of you've developed your own preferred way to trade and I'm not saying you are wrong but don't you think locking it until it to rebound may takes months or even years. Imagine, during the locking period, you may lose a lot of opportunities to buy some other potential stocks. For your info, I've just cut another loss for SBC at around 0.90(purchased at 1.0) and lowest it hit 0.64(hell, that's around 26% dropped but I managed to stop the bleed earlier and lucky to collect some other good counter that rebound after that). Well, I guess am just lucky again...
