标题: 急问leverage ratio的问题 [打印本页]

作者: gissel 时间: 2011-3-24 12:30 标题: 急问leverage ratio的问题

是note上的题，book4，P214

"for example an investor wo satisfies an inital margin requirement of 50% equity has a 2-to-1 leverage ratio so tha a 10% increase (decrease) in the price of the asset results in a 20% increase (decrease) in the investor's equity."

我觉得这个results in a 20% increase有错，我觉得应该是5%的increase。

因为leverage ratio = Vaule of assets devided by value of equity position. so 2-to-1 leverage ratio means that value of asset is 2 times of value of equity. so the 10% increase in price should incur 10%/2=5% increase in value of equity.

Don't you think so? 我不明白书上的意思。是不是书上写错了呢？求真相！！！！！！！！！！！！

will give you an easy example...

Price of stock is $10, initial margin is 50%, so your equity is $5. When price goes up by 10%, it becomes $11... so your profit is $1, with a cost basis of $5... your return is 20%. Leverage could multiply your gain as well as loss... it is a double sided blade
