http://mebfaber.com/timing-model/His very simple strategy is to sell when the total return of the S&P 500, or whatever is below the 10 month moving average (sampled monthly) and buy when it is above. There is a 10 year out of sample review of his original paper (which I have not managed to see yet) and apparently the approach has beaten the S&P over the period, despite the long bull market. I suspect the reason is that the strategy got out of the market on the way into the financial crisis. It may not look so good once that bear market falls out of the 10y figure.
I keep 25% in global equities (mostly cap weighted ETFs/trackers), ..........If I was going to hold a lot more than I do in equities, I think I would probably follow some systematic strategy such as Faber's with part of the allocation as some timing strategies do seem to reduce losses during major market drawdowns. The price to pay, there is always a price, is that some buy and sell signals will turn out to be false alarms.
Thank you for this.
I had a bit of spare time today and read that updated paper you cited which can be downloaded here:
https://papers.ssrn.com/sol3/papers.cfm ... _id=962461The motivation can be summed up as:
1. Diversification is good, but not enough.
2. LTBH through serious down-periods sucks.
3. So find something to take emotion out of
the timing of the sell and buy decisions.
A quote stuck out for me
" The former manager of the Harvard endowment, Mohamed El-Erian stated in Kiplinger’s in 2009, “Diversification alone is no longer sufficient to temper risk. In the past year, we saw virtually every asset class hammered. You need something more to manage risk well.”"It uses two rules as you say:
BUY RULE: Buy when monthly price > 10-month SMA.
SELL RULE: Sell and move to cash when monthly price < 10-month SMA.
I then ran this through the four Vanguard funds I use, and two of the other big & large cap positions I have, and got the following results. Note I am using the staus nomenclature of being IN or OUT, and the last change date (ie. when last SOLD or BOUGHT):
Item | Status | Turned
= | = | =
VUKE | out | 01-Feb-18
VERX | out | 01-Feb-18
VAPX | out | 01-Mar-18
VWRL | out | 01-Mar-18
= | = | =
RDSB | in | 01-Apr-18
BP | in | 01-Apr-18
Looking at that, and the underlying trends in each of those charts (I just used HL with the 200d SMA switched on, with a 3yr monthly view), I do slightly wonder if there should be an intermediate status IN-HOLD-OUT to prevent too much churning. However the back testing, and post-testing, they have done shows that even the two-status version has so-far been providing increased returns compared with LTBH. It is certainly food for thought that all four of those indices have a sell signal on this basis.
