Lets wind the clock on from the last post of this thread and see how we would have done if we had bought into that particular narrative..
Well, if you had invested in the S&P, in USD , the answer is you would have made a lot of money. While, as ringledman correctly points out in post # 3, “
We are now around 15-20 times on the CAPE for the USA market which still signifies overvaluation.” investing in the S&P in Aug 2012 would have resulted in a gain of 51% to last Jan. In this period the Schiller CAPE moved from 21.41 to 26.96, both well above its historical average of 16.57.
I haven't been able to locate CAPE or any earnings related data for European stock markets, but if you had invested in the Eurostoxx50, in euro, in Aug 2012, which according to ringledman, was “
more tempting on around 10 times the CAPE”, you would have gained 24%, to last Jan. Not bad but not as spectacular as the gains the US investor would have had.
Two years is a rather short duration to reach firm conclusions on this issue, but, based on recent performance, there is little evidence here that equities are 'dead'. In this two year period, developed market equities (i.e. US, EU, and GB) protected you from declines in other asset classes (e.g. commodities, emerging market equities) or those that gave more modest returns (e.g. property), assuming you have a diversified portfolio.
Now these gains are counter intuitive, as investing in high priced assets is supposed to lead to lower returns in the long term than investing in more reasonably priced assets. But if ringledman did as he said “
I am staying defensive. Boring value, large caps with decentish yield that are already on P/Es of below 10. Invest for income for a few more years and hold a large allocation in cash”, he would have gained as developed market indices are large cap indices, which increased in value, and holding cash would have maintained capital values that you would have lost if invested in commodities and emerging markets.
