A Retrospective on the Stock
Market in 2000
by John
B. Carlson and Eduard A. Pelz
Should the end of the bull market have come as
a surprise?

When
we look back at the 1990s, from the perspective of say 2010....We
may conceivably conclude from that vantage point that, at the turn
of the millennium, the American economy was experiencing a once-in-a-century
acceleration of innovation, which propelled forward productivity,
output, corporate profits, and stock prices at a pace not seen in
generations, if ever. Alternatively, that 2010 retrospective might
well conclude that a good deal of what we are currently experiencing
was just one of the many euphoric speculative bubbles that have dotted
human history. And, of course, we cannot rule out that we may look
back and conclude that elements from both scenarios have been in play
in recent years.

Federal Reserve Chairman Alan Greenspan
Excerpt from speech given to the
Economics Club of New York on January 13, 2000

The
stock market began 2000 the way it ended the decade of the 1990s, surging
to new record heights (see figure 1). Because
stock markets are by nature forward looking, it appeared as though investors
were convinced that the economy would play out according to the first
of the alternative scenarios posed by Chairman Greenspan in the quote
cited above. The sharp acceleration in measured productivity in the
late 1990s, no doubt, reinforced such optimism.
Nowhere
was optimism more apparent than in the NASDAQ, which is dominated by
large technology firms, especially those most likely to prosper from
developments in e-commerce and the Internet. In March, however, the
mood shifted. The NASDAQ, which had surged past 5000, began a descent
that would leave it about 50 percent below its peak at year-end. The
S&P 500 finished the year down about 15 percent from its peak and about
10 percent below where it had stood at the end of 1999. Despite the
sharp declines over last year, both indexes remain more than 400 percent
above their 1990 levels.
What
can account for such a wild swing, particularly in the NASDAQ? Was the
rapid run-up and subsequent fall, as some have claimed, the bursting
of a technology bubble?1 Could one have known before
the slump? This Economic Commentary addresses these questions. We begin
by reviewing fundamentals and their implication for price-to- earnings
ratios (P/Es).
|

|

P/Es
and Fundamentals |
| |
Stock
price listings in the business sections of most newspapers typically
include both the firm’s closing price and its P/E. The P/E is simply
the ratio of a firm’s stock price relative to its most recently reported
earnings per share (current earnings). P/Es provide a sense of an investor’s
potential income from owning a stock. For example, consider two stocks
that have the same current earnings and different expected future earnings
but are otherwise identical.2 Clearly, investors
are willing to pay more for the stock of the firm that they anticipate
will earn more in the future. In fact, P/Es are often quoted in terms
of a multiple of earnings, for example, “10 times earnings.”
The role of the path of future earnings in determining the P/E is straightforward.
The rate of earnings growth determines a firm’s potential to provide
returns to shareholders, either in the form of some future payout (such
as dividends or stock repurchases) or through stock price appreciation.
The faster earnings are expected to grow, the greater a firm’s potential
ability to compensate shareholders and the higher its price relative
to its current earnings (that is, the higher its P/E).
Historically,
the P/E of the S&P 500 index has averaged around 14 (see
figure 2).3 During late 1998 and much of 1999,
the P/E of the S&P 500 index reached unprecedented levels—indicating
that many believed potential earnings from ownership of these firms
had increased substantially. As of December 2000, it had fallen to just
below 25.
Apart
from optimistic earnings projections, there are a number of reasons
why investors might have expected P/Es to rise to higher average levels.
First, there is clear evidence that recent developments in information
technology have sharply reduced shareholder costs. A decrease in shareholder
costs allows more earnings to be passed along as income, and so has
the same effect on P/Es as an increase in expected future earnings.
Figure 3 illustrates the substantial decline
in the annual total costs of holding an equity mutual fund. In an earlier
Economic Commentary, we illustrated in some detail how declining shareholder
costs affect stock prices and expected future returns.4
We showed that seemingly small declines in shareholder costs can lead
to large increases in stock prices.
Moreover,
such technological improvements mean permanently lower costs and potentially
higher diversification. Diversification allows investors to offset the
risks associated with an individual stock, so-called idiosyncratic risk,
by holding a portfolio of stocks that respond differently to economic
phenomena, such as those of an oil- producing firm and an auto manufacturer.
A number of analyses find that, together, lower transactions costs and
greater diversification can account for some of the recent ascent in
stock prices but not all.5 This evidence tends to
support a substantively higher average P/E if we assume expected earnings
growth to be around its historical trend.
Another
factor that may account for higher P/Es in recent years is the potential
for credible tax cuts. As the U.S. federal budget changed from chronic
deficit to growing surplus, the prospect of future tax cuts became increasingly
likely. It is impossible to know precisely what impact this expectation
might have, but it seems reasonable that expected tax cuts, particularly
those on capital gains, would push P/Es marginally higher.
|

|
| |
The
S&P 500 |
| |
P/Es
over 30 require a quite sanguine outlook for earnings growth for both
the near and long term. Figure 4 illustrates
why optimism in earnings may not have seemed outlandish. Earnings in
S&P 500 companies grew at extraordinary rates over the last half of
the 1990s. Moreover, at the beginning of 2000 analysts were projecting
continued high growth over the next five years. By the second half of
the year, it became clear that rapidly rising energy prices were likely
to cut into corporate profits, despite a notably lower reliance on energy.
Moreover, a decline in consumer confidence, coupled with a severely
cold December, led companies to revise their reported earnings down
sharply, which further damped earnings prospects.
In
retrospect, the decline in the S&P 500 largely reflects a number of
events that affected key fundamentals. On the basis of the S&P 500’s
performance in 2000, investors apparently got ahead of themselves. With
a P/E currently around 25, the S&P 500 still embodies a fair degree
of optimism, but arguably not an unreasonable amount.6
The NASDAQ, on the other hand, tells a different story.

The
NASDAQ |
| |
The
NASDAQ, like the S&P 500, is a value-weighted index. This means that
price movements in firms with large capitalizations can dominate index
movements. In recent years many of the largest NASDAQ companies have
been technology firms. Because of this, NASDAQ movements have largely
been associated with developments in the technology sector. Indeed,
the huge swing in the index during 2000 largely reflected the pattern
of some of the largest technology stocks. So to better understand the
rise of the NASDAQ’s level and its subsequent decline, it is instructive
to consider the P/Es of the largest firms in the technology sector.
A
telling analysis of large-cap technology stocks appeared in an article
by Jeremy Siegel in The Wall Street Journal near the market peak last
March.7 Siegel focused on the 33 largest firms based
on market capitalization—those with values greater than $85 billion.
Of these, 18 were technology stocks. Siegel noted that their market-weighted
P/E equaled 125.9 on March 7, 2000. What’s more, he notes, half of the
large-cap technology stocks had P/Es over 100. For these stocks, the
market-weighted P/E was 208.2
Siegel
then contrasts such P/Es with projected earnings growth rates from I/B/E/S
International and historical experience. He finds that once a firm reaches
large-cap status—ranked in the top 50 by market value—its ability to
generate long-term, double-digit earnings growth slows dramatically.
Moreover, he finds no example of a large-cap firm to ever justify, by
its subsequent record, a P/E anywhere near 100. He concludes that the
market for technology stocks has been driven to an extreme not consistent
with historical experience.
Siegel
does not deny that the excitement generated by the technology and communications
revolution is fully justified. Rather, he emphasizes that this does
not automatically translate into market value. His analysis does not
preclude that in 2010, we may indeed look back on these times as an
unprecedented period of prosperity. Siegel’s point is simply that even
if we are witnessing a substantial revolution, it is not clear that
firms can continue to earn returns so far in excess of historical averages.
In
the months that followed the market peak, it became clear that large-cap
technology stocks were priced with no margin for error. That is, even
if one believed that the technology sector of the economy had entered
a regime that supports permanently higher stock prices and P/E ratios,
it was further necessary to accept that these particular stocks could
generate earnings growth at a faster pace and for a longer duration
than any large-cap firm in history, in order to justify their valuations.
We
conclude that the rise and fall of large-cap technology stock valuations—and
their consequent impact on the NASDAQ—is compelling evidence of a bubble
that was destined to burst. As Siegel’s analysis demonstrates, one could
rationally conclude prior to the peak that these valuations were vulnerable
to any signs of near-term weakness.8 Fortunately,
the euphoria was contained. The imprint of the bubble on the S&P 500,
though significant, was muted. After taking account of the 15 percent
decline off its peak, one is reminded that the S&P 500 remains 400 percent
above its 1990 level.

Concluding
Thoughts |
| |
When
looking back on 2000 from today’s vantage, the recent exuberance in
the technology-sector stocks was not validated by the economic news
that unfolded over the balance of the year. Dampened consumer spending
and the inevitable deceleration in computers and software investment
that followed Y2K-related refurbishing and upgrading seemed to be less-than-fully
anticipated. These events were enough to induce investors to adopt a
more cautious perspective on profit growth.
This
sharp decline in technology stocks should not be taken to mean that
innovations in technology will fail to propel productivity and corporate
profits forward to a pace not seen in generations. However, it is not
just the prospect for growth that matters. Growth, if it occurs, must
also generate sufficient profits to adequately recompense equity owners.
Vast profit potential creates huge incentives for more entrants into
new and lucrative markets, and competition tends to reduce the profit
margins of individual firms.
We
want to emphasize that the current vantage reveals very little about what
one might expect to conclude in 2010. However, we suspect it probable
that elements of both the Chairman’s proposed scenarios were in play.
The economy appears to have entered a period of sustained productivity
growth, but one cannot know the extent to which it will persist. Stock
valuations will hinge on investor confidence that strong productivity
will continue. As we’ve seen, this confidence can swing wildly.

1.
Here, we loosely define a bubble as the rapid increase of an asset’s price
such that the current value of the stream of expected future income is
so high that there is little probability of making a profit given that
valuation. Oftentimes, bubbles begin when legitimate profit possibilities
cause prices to rise. Prices are then driven past valuations justified
by economic fundamentals, as speculators attempt to profit solely by trading
the asset.

We have not considered the traded prices of Internet startups, that
is, the infamous dot-coms. There seems to be little dispute that their
market values could not be justified on the basis of fundamentals.
