There's evidence that stock prices, and even GDP, might have unit roots in them, meaning that their variances goes to infinity over time! <br /><br />Thus, if you're using the current variance in an asset as an approximation for risk, and the variance is actually increasing over time, you would not only be wrong in your current assessment of the risk, but you would probably also be wrong in using the variance as a proxy for risk at all. <br /><br />This brings to light another interesting question. What is the risk of an asset following a unit root process, and consequently with infinite variance? And, if stock prices, like GDP, do have unit roots, are we setting ourselves up to fail with our current approach to finance?Vulcidianhttps://www.blogger.com/profile/09900944456971799548noreply@blogger.comtag:blogger.com,1999:blog-7383770159894409699.post-77037510288030971822010-03-09T06:21:12.381-08:002010-03-09T06:21:12.381-08:00Excellent analysis.

Because of this I just used a simple 10% discount rate.<br /><br />I did leave my model so that you can go in and plug in any rate that you want as the discount rate, so if you want to you can download it and play around with it.<br /><br />Thanks for the comments!The Sane Investorhttps://www.blogger.com/profile/08514525821806713140noreply@blogger.comtag:blogger.com,1999:blog-7383770159894409699.post-89917521543137412902010-02-22T07:42:03.826-08:002010-02-22T07:42:03.826-08:00Why do you use a 10% discount rate?
