I used to buy at 2, but sell at 2.5. Like what you said, take profit at the right time. But now you see how much it has gone up? For me, short term trading always lose long term investing. Now I buy in again at 3.8 and will hold it for many years, as long as this company business continue to grow.

u sold at 2.50 and never revisited it until 3.80, thats your loss la...for me, if i take profit now, i will keep following it and revisit when there is another chance bcos up and down is always a stock's cycle. That way, u will not only earn once. Mi's highest point was 4.88 and it went back to 3.60, if u dont take profit at high point, u will go back to square one cos u will nvr know the future. investing is also about taking profit or cutting losses, and not just holding power.
