As I'm struggling to use the 'Quote & Reply Facility', this reply is to Dub_Nerd above:
I made no direct reference to 'timing the market', but by inference if a market is overvalued relative to history it is at least a yellow flag. But as the booklet highlights, overvaluation is not so much a danger to the 'Regular Investor' as it is to the 'Lump-sum' investor. The latter doesn't get to go again, so valuation is extremely important at the point of commitment. The Regular Investor and Lump-sum Investor have different issues to deal with. In 1999, it was not particularly important to the Regular Investor that the S&P 500 - or markets in general - were overvalued then, as he/she was not committing all their monies at that time, but investing over time.
However, if history is to be a guide in terms of valuation then there's more to it than has been argued above. For example, in 1999, the US stock market was trading at a very high multiple of earnings relative to history. If we take it that the S&P 500 was trading at 30 times earnings in late 1999 (I don't have the exact multiple), then that's the same as an earnings yield of 3.3% (100/30 expressed as a percentage). It's easier to use the earnings yield as it can be compared to bank deposits, rental yields on property or the yield to redemption on government or corporate bonds. At the time in late 1999, that 3.3% earnings yield could be compared to the risk-free 10-year US government bond yield of circa 6.3%. So, not only had you overvaluation in US equities when compared to history, but you were being offered much better value in the risk-free alternative.
So, yes, in this context you might choose to 'time the market' by investing where the value was better. It may be market timing, but it is so on the basis of values. In other words, value can be a market timer for an investor. And market timing this way is not speculating, it is the very essence of sound investing, which should be on the basis of value. If the Irish had any understanding about 'value' they would not have been buying Irish property post 2002, if not before. But not only were we piling in, but we were doing so with debt. It did not take a genius to work out that it made little investment sense. Hence, my opening para in the booklet 'learning how to save and invest is not a luxury in life; it is a crucial part of our lives and we need to be more informed'.
Today, in my view, it's not so clear cut that the key US equity market is significantly overvalued. Yes, we have the S&P 500 trading on circa 21 times earnings for an earnings yield of 4.7%. Yes, this earnings yield is well below the long-term average, which is a yellow flag, but perhaps not a red flag. Today, unlike 1999, the yield from a risk-free 10-year US government bond is 2.55% (when I last checked), which is well below (not above) the S&P 500 earnings yield. Today, it's tricky. It's not always necessary to have a definitive view. I don't have one at present. I neither feel the key US equity market is overvalued nor undervalued. I appears fairly valued relative to the alternatives. After all, how do you price an asset when interest rates are so low. If you believe long-term interest rates are going to be this low for several years then it is right equities are valued higher than was the case historically. In 1999, the bubble was in equities. In the mid-2000s the bubble was in property, and no more so than Irish property. We Irish do go to extremes! Today, I'd venture, the bubble is in developed world government bonds unless you believe in deflation. The 35-year old bond bull market in the developed world, that started as long ago as 1981, most likely ended last July. As they say, long bull markets rarely end softly!
These principles are all outlined in the booklet. I believe the more one reads the booklet, the more you will get from it. I am on my third read of 'Money, the Unauthorised Biography'. A superb piece of work by Felix Martin in the UK on the history of money. But if you follow my lead and buy this book, be forwarned that's it demands good initial insight to get the value.
I, like others, can see the remarks on this thread. I'm encouraged to see some saner voices making an appearance of late. In the booklet, there's 30 years' experience in 56 pages written in easy-to-follow language. Lord John Lee, columnist with the Financial Times, recognised that and hence the 'Foreword'.
However, it's a decent guide, not gospel...we might leave that to Warren Buffett. So, anyone is entitled to argue with points in the booklet and make their own points. That's debate. But before you add to the debate, have the common curtesy to read it first, as I will not engage with those who see a need for argument without facts to back it up.
