To my understanding, long-short is to long undervalued stocks and short overvalued stocks, and then use the proceed to buy more undervalued stocks. For 120/20, you can only short up to 20% of notional in long positions for leverage purposes. What does "coordinated portfolio" mean? And why is this not part of long-short investing strategy?
Thanks for looking into this!

coordinated指的是你买130/30是一对股票，比如，A低估、B被高估，那么你short30B，然后做多130A。而uncoordinated可以投多只股票，比如，A低估、B被高估、C低估，那么你可以100买A,30卖B，再卖30C。
加油。

再买30C

所以technically speaking, long short strategy也可以做pair trading: 买A卖B 然后接着用卖B的钱去买A？只是120/20大多做pair trading?

不是大多，short extention只做pair trading.所以才是coordinated portfolio。
