Like MPT, market efficiency leading to the Market Portfolio of all risky assets being optimal has many assumptions about risk, investor behavior, etc etc. And some people like me scratch their heads and ask why two seperate concepts have been merged in the same sentence. No need to come up with dif...

I haven't read the paper. But I can tell you what I know with playing with all sorts of spreadsheets containing historical data. Yes, savings rate does matter. But only before the nest egg has grown to a certain amount, say, $200,000 or thereabouts. After that, the rate earned on those savings matte...

I've got news for all you so called no tilt people out there, if you own VTI, or any other single ETF, or mutual fund that owns the markets, then you're tilted toward large cap stocks. So dump the this argument about tilting being a bad thing. VTI et al are "tilted" to whatever the market...

On the other hand, portfolio efficiency means that there is some combination of stock asset classes that will fall on the efficient frontier. Of course, we can never know that optimal combination ahead of time. But we can look at history to see how it turned out. Click on image for full size. http:...

As far as reversion to the mean, John Bogle has excellent writing on this in his book Common Sense on Mutual Funds . I recall other authors writing about it as well. From what I remember it occurs to various mutual funds as well as individual asset classes. For me it confirms my decision to go for ...

Efficient markets mean that the longer the time frame the less likely it is for active managers to outperform a benchmark index. Think Bill Miller as a recent example. On the other hand, portfolio efficiency means that there is some combination of stock asset classes that will fall on the efficient ...

I would cast a "NO" vote. I don't see it necessary to add any more lines. It'll just clutter things up.

Yes, I think that chart is accurate for someone whose holding period is a year - but then, they shouldn't be owning stocks in the first place, as the chart implies.

Maybe this will covered in part 2. But it seems your figures are bi-model (tri-model?). Perhaps in the sub-section on Asset Allocation , you can make the point that risk can be somewhat controlled by how much or how little you have in risky and less risky assets. Use a chart like this for illustrati...

Also there is no need to take risk. This stuff about risk as a need is straight from Larry Swedroe who is not an academic. Swedroe is often wrong when he talks about risk and this is one of the many cases where he is wrong about risk. This was already discussed. But apparently it didn't sink in. So...

A person would have to be in extreme dire straits having burned through all other cash, CDs and other fixed income accounts to have no other choice than to tap their long-term retirement accounts holding stocks in order to put food on the table.

Why single out QE3? Aren't there dozens of potential policy actions that will affect investors? Or is your response to change your portfolio in different ways depending on the policy action implemented?

It's common for novices to have someone like your Metlife person helping you with your investments. And as you've learned, that advice is not free.

I wouldn't consider Forbes a "mainstream" media outlet. The Atlantic might be more "mainstream".

What are some of the most popular "mainstream" media outlets that most Americans read? The national paper USA Today?

This is hindsight bias: You know sometimes you don't necessarily have to be a lemming and fall off the cliff and "stay the course." There were numerous indications the US economy was in a severe real estate bubble in the mid 2000's that would end badly. What very few knew was that the fail...

Going by the comments here so far (I haven't read the article), it appears that Malkiel makes the common mistake of examining portfolio components in isolation, and not how each lend their support to the whole.

bob90245, do you agree that the data I've presented is reasonably accurate and reasonably objective, and that the issue is not the fact but how to act on them?

To pick a convenient source, the 2010 SBBI yearbook. There are the usual problems here. The "bonds" allocation is represented by long-term government bonds, which is probably not a typical Boglehead practice, and these are real, not nominal returns. But, here's the data, and I insist that...

Tilting can also add diversification. You want to have sufficient exposure to all equity asset classes (market, value and small) to guard against periods of underperformance. JG, you sum up nicely a significant reason to tilt. The period 1995 to 1999, and then 2000 to 2010 is a prime example of per...

I read the book. But in follow up articles, he departs from his advice in his book. Bodie now has said that if you are an investor in your 20's and 30's, you don't need to put 100% of your nest egg devoted to base retirement needs into TIPS and IBonds.

All this seems like excessive semantic precision, yet there is a big difference between diversifying across "asset classes" and "asset class categories" (Personally I don't like that term and would call them sectors, flavors or class members, but you get my meaning) If you prefe...

PE10 at the beginning of 2012 was 21.68. It would have to drop by more than 50% [to below 10] by the beginning of 2013 to signal a move from 100% Treasuries to 100% TSM using this decision rule.
