Again, you need to do what you have said. If you think XIN is the best undervalued stock in the exchange, your current XIN position of only 6% of your portfolio does not make sense. Are you telling the others your other 94% of the portfolio may have higher return potential than XIN does? If so, you did not tell everybody what exactly you believe.
I can't speak for Connor.jin but your post makes little sense. "Higher return potential" is not the only factor in designing a portfolio, dude. Putting your whole portfolio into the places that offer the highest return potential is a quick way to go broke fast. XIN is a great buy as part of a balanced portfolio given the risk-reward right now, the consistent growth and now stock buyback and dividend. I am mostly in cash right now, but in case the entire world economy does not completely blow up, XIN should show very nice price appreciation.
Your post showed you never read my post. I mentioned so many times that I am a share holder of XIN. I am just considering cutting my holding a little bit. So, I can use the proceeds to buy something else that offer better return potential.
Shorting is a totally different story. The last thing in the world I would do is to short XIN. There are tons of stocks out there that would yield higher return potential if I short them. Also, I don't short stocks unless I have some really good information making me to do so.
