John H. Cochrane有一篇論文
<<Portfolios for Long-Term Investors>>
( https://www.johnhcochrane.com/research-all/long-term-portfolios )
我覺得很值得一讀
裡面提供了許多觀點
不管你最後同不同意
都很值得至少思索一番
===
容我引用其中的一段話:
"The average investor must hold the market portfolio."
"The average-investor theorem is powerful, because portfolio theory is hard.
You have to estimate or otherwise understand time-varying means and
covariances of asset returns and state variables, alphas, and betas. Then you
have to make a difficult computation, and do a lot of massaging to keep it
from blowing up."
"But if you know that you are no different than the average—
or if you do not really know you are different and how—you are done, you
know the answer. Off to the total market portfolio with you."
--
So stand by your glasses steady,
Here’s good luck to the man in the sky,
Here’s a toast to the dead already,
Three cheers for the next man to die.
