The Crocs (CROX) stock is on a roll lately, as it’s closing 3rd quarter and holding two investor conference (link to webcast) in NYC and London. I added some more CROX last week when the escalator accidents is on the news. Another reason is I sold WX. I think both CROX and WX are good long term but I want to bet on “more sure” things.

Mindray (MR) has also done well lately. Incidently it’s also holding a conference in the US. At this time the fastest growth will from the US market. Chinese domestic market will also have some growth but the goverment still yet to roll out reforms in the health care (hospital) industry. Notheless I think (for the good or bad) Chinese patients still got to see doctors, so I’m not worried about MR’s prospect in China.

一次，诺贝尔经济学获奖者数学家约翰·纳什参加一个数学年会，会间休息的时候，有人就给他出了一道数学题。有甲、乙两人分别从两个地点出发往中间走，这两个地点相距 20公里，甲、乙两人的速度都是每小时10公里。甲还带了一条狗，这条狗的速度是每小时30公里，它先是和甲一起出发向乙走，遇到乙后就折返向甲走，遇到甲后再折返向乙走，如此反复直到甲、乙在中间会合。现在问当甲、乙在中间会和时，狗走了多远。

Two people (guy A and guy B), who are 20 km away from each other, are walking toward each other, at 10 km per hour. There is a dog, which goes at 30 km per hour. She (the dog) started with the guy A first. Because she goes faster than A, so she will meet B on the way. When she meet the B, she will turn around to run toward A, and so on,…until A and B meet. The question is: how much distance did the dog take before A meet B?
