Here is the way: Hold your shares firm and check XIN price once a month. You will double your money sooner than you think ---- plus you only need pay long term capital gain.
I can say this with certainty that all those traders who in/out stocks quickly and post lots of messages on Yahoo message board are losers. Only their spouses know how much money they have lost on Wall Street.
If you want make money, first thing to do is to stop trading. Become a value investor. Buy and hold value stocks like XIN. You will do very well over time.
XIN is building in NYC and can fetch about $200 million in profit in its NYC project in 2014. The street is paying attention to that. Looking forward to seeing XIN to start projects in both LA and SF markets. If that happen, XIN can be valued as a US home builder with a PE = 20. Then XIN can top $30 if XIN is traded like PHM or DHI.
