The data you have pointed to is pretty limited.Pretty different to looking at all available data for 20 year periods.
That's ridiculous Sarenco!! - that's akin to saying that past performance is somehow not a reliable guide to future performance!
Also looking at 20 year periods over 100 or 200 years is pointless as far as statistical analysis goes , its can never be used to prove a point.
In any event, the future has no obligation to mirror the past.
That's really the key point that you're missing for some strange reason.
A typical financial model would posit that equities enjoy an average risk premium over cash of c.3% p.a. but with an annual volatility about this long term trend of c.15% p.a. On this model there is an 18% risk that equities will under perform cash over 20 years and there is a 82% risk that cash will under perform equities over the same time frame. So over 20 years which is the riskier?
As mentioned before, I think the model actually overstates the risk of equities versus cash as there are systemic checks and balances to help equities out of crashes. I don't know whether the criticisms of GG are because of his absolutist statements but putting absolutism aside I think he is substantially correct.
Why?
An S&P investor with a 20 year time-horizon has never lost over the 150 years of available data (backfilled pre-1926). Even the poor guy who invested the day before every major shock.
Yet you’re disputing that people are safe from permanent loss of capital over 20 years from today.
I would venture that it is you guys who do not understand risk.
Okay, the absolutist statement obviously does not hold.
That’s not the argument Duke. Absolutely nobody is arguing about the benefits of equities over cash over a long horizon. The argument is that investing in equities is risk free over 20 years.
I've re-read this thread and in fairness to Gordon his key message that a long-term buy and hold approach has been successful in stock market investing history is valid. In saying this, I do not wish to diminish the points made by other posters which I understand and appreciate and I don't agree with everything Gordon has said.
However, on a relative scale his position is certainly far more appropriate than the moon is in the third phase of Shani Sade Sati approach that I derided way back in post 7 of this thread.
But you are ignoring risk. Over the 20 year period your annual returns fluctuated. Take, for example, a “made up” index that lost 54% in 1998 and its subsequent returns were those of the S&P500 for that period. By the end of 2017 your capital sum has returned to its original amount, but in the period concerned your returns have fluctuated with a standard deviation of about 21%. This is real risk you have taken on and for which you have not been rewarded. If you assume a risk free rate of about 2.75% on a long duration bond, you've a negative Sharpe ratio of about -13%. You have not made a wise investment as you have not been rewarded for the market risk you have taken on. It's not just that you get your capital sum back , it's that you get your capital sum back and also are rewarded for taking on market risk. Otherwise you put your savings directly in government bonds or analogues.An S&P investor with a 20 year time-horizon has never lost over the 150 years of available data (backfilled pre-1926).

But let's assume what you say is correct, and that investing for 20 periods does not result in a capital loss. This implies long duration investing is equivalent to buying a bond that will deliver a capital sum equal to your original investment after 20 years (or whatever your selected time period). If this were true, it has happened only because at the start of the 20 years period, stocks were priced to deliver returns the sum of which are equal to your initial investment over the period concerned. If the price at purchase is higher you have a longer duration to wait for the accumulated returns equal your initial investment and if the price is lower your duration is shorter. The 'price' of a stock market is its price/dividend ratio. If you assume the dividend rate is constant, the price of the index must also grow at the same rate as dividends over the period concerned. Currently, for the S&P the dividend yield is 1.84% (end 2017) http://www.multpl.com/s-p-500-dividend-yield/table, so the price/dividend is about 42, which implies a holding period of in excess of 40 years as of today. So those starting out investing today, and only these people, should be totally invested in stocks, as current prices imply a risk free investment, if you hold until you retire.
Of course that nobody has a crystal ball but, if you believed that the stock market will crash soon enough... where would you put your money?
bonds, cash?
Just to highlight the point again that the majority of Irish people that got wiped out in the financial crash did so because of bad investments in property not in stock markets. Even people who lost out through investing in bank shares are a small proportion of the wealth that was permanently lost through property investment. Yet people are still overly cautious and suspicious of the stock markets and everyone is back gung ho into property investment . You rarely see people on the property investment threads now talking about a risk of a big fall in property prices
