Roger, Strong-arm!Be advised we have incoming from the tree line at point blue plus two!A.K. s and rockets!

VOA: standard.other

And our job is to find out what is the mathematical description of this path, this line in p-V's case that connects these two point.

我们的任务,就是找出，描述这条曲线的方程。

That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.

在这一选择下,我们会发现一件非常有趣，而且极其重要的事,当你把这两点用直线连接起来，你会发现这条直线,将与x轴在某点相交。

I can try other portfolios; this one right here--I'm pointing to a point on the pink line-- that point right there, 50% stocks, 50% bonds.

还可以尝试其它组合;,这一点，粉色曲线上我指的这一点-,表示50%的股票，50%的债券。

That means that you want to pick, ultimately, a point on this-- this line is tangent to the efficient portfolio frontier with all the other assets in it.

那意味着你会最终会在这上面选一个点-,这条直线是与有效边界相切的,后者包含了所有的资产组合。
