In the above chart we had S&P
earnings data available back to 1960.
From this chart we can see that
the S&P 500 earnings level has risen (albeit in a lumpy fashion) with GDP.
It seems clear from this chart that if GDP continues to rise then S&P 500
earnings will (within a few years at most) follow suit and rise. And if S&P
500 earnings rise then the S&P 500 stock index must rise, assuming that the P/E
ratio remains constant or rises (about which more below).
The chart also shows that
earnings are not currently at a high peak in relation to GDP. If earnings
were at a high peak then we might have a period where GDP would grow while
earnings did not. From the graph it appears that if GDP grows, then earnings
on the S&P 500 index will grow.
The U.S. GDP line in blue here
is in nominal dollars. We are more used to hearing about the growth of GDP
in real dollars after deducting inflation. In nominal dollars U.S. GDP has
risen very steadily over the years. Since 1940 there have been occasions
where GDP was flat for a year but certainly no dips are evident in the
graph. And it appears that since 1940, it has never failed to rise over a
period of about three or more years. However, during the depression years the GDP
did fall materially.
If you believe that there is a
strong chance that we are headed for a depression then you should have a low
or possibly zero allocation of investments to stocks.
The consensus of opinion is that
the North American and possibly the world economy is in a recession. The
Stock market has already fallen about 40% and therefore may have already
"priced in" the recession. It's possible that the stock market has already
bottomed and will not go lower even if the recession worsens. But that can't
be guaranteed. It's possible that the stock market will fall further as the
recession deepens.
If you believe that the recession
will worsen and that stocks will go lower and that you can pick the bottom,
then you should not invest now and should instead position yourself to be able to
buy stocks at lower levels.
If you believe that the
recession will be mild and that GDP will continue to grow and that stock
earnings will follow suit, and if you are not convinced that you have the
ability to pick the bottom then it would seem to be wise to invest now to
take advantage of the "40% off" sales prices. (It would also be
wise however to be positioned to buy additional stocks if the prices do drop
further.)
Before deciding whether stocks are a good investment now, it is worth examining whether or not P/E ratios
are likely to rise or fall.
Firstly, what is the P/E ratios
for major stock indexes at this time?

*The average P/E ratio on the
Dow Jones Industrial Average since 1929 has been 15.5. This is based on
year-end data and excludes several spikes that were related to abnormally
low earnings (1982 at 114.4. 1991 at 64.3 and 1933 at 47.3 are excluded from the
average).
P/E ratios (of broad stock
indexes) generally fell during
the past few years. However, more recently due to huge losses at some
companies, P/E ratios have started to increase. If the impacts of large
losses at a few large companies are omitted then the current P/E ratio
appears to be approximately 12.
The following two charts
illustrate that at 12, (or even if it is 15) the current P/E ratio is below average. The graph
also shows that the P/E ratio has at times gone lower and has on some
occasions remained under 10 for several years.
