Below is an extract from a commentary originally posted at www.speculative-investor.com on
3rd May 2007.
US corporate earnings for the first quarter of the year were generally above
analysts' expectations and this has been trumpeted as an important driver of
the stock market's recent advance. As usual, though, there's a lot more to
the story than meets the eye.
Firstly, it is worth noting that expectations were only exceeded because the
bar had previously been lowered. Specifically, company managements did a stellar
job of getting analysts to lower their forecasts and, as a result, these companies
only had to earn what the analysts had originally expected them to earn in
order to come in well ahead of the revised (lowered) expectations.
The lowering of the 'expectations bar' is only a small piece of the puzzle,
however, because a) the price action tells us that the market never actually
fell for the lowered guidance (there's often a difference between the consensus
expectation of analysts and the market's expectation), and b) the stock market
rally continues to be a global phenomenon. When attempting to explain the stock
market's recent strength we therefore needn't devote much time to the expectations
game played by US company managements and Wall Street analysts.
Secondly, in a recent
article Doug Kass makes the good point that the quality of earnings growth
reported by corporate America during the latest quarter was poor because
a significant chunk of it was due to the boost to internationally-generated
profits provided by the US dollar's weakness.
There's a comment towards the end of the Kass article to the effect that while
most people who think about how the currency market could impact the future
performance of the stock market appear to be focused on the risk posed by dollar
weakness, there might actually be more potential for a problem to stem from
dollar STRENGTH. We agree -- substantial strength in the dollar would put DOWNWARD
pressure on US corporate earnings. But while we think the performance of the
currency market is a critical factor in the stock market's rally we don't think
the foreign-exchange-related boost (or lack thereof, should the US$ strengthen)
to US company earnings is the most important aspect of the currency-equity
relationship at this time. The fact that it's a GLOBAL, not a US, stock market
rally tells us this much in that any benefit achieved by US multi-nationals
due to US$ weakness relative to the euro will have been offset by the lowered
earnings of European multi-nationals; and yet the senior European stock markets
have been performing at least as well as the US stock market.
Thirdly, skeptics have rightly pointed out that per-share earnings have been
elevated by corporations buying back their own shares. For example, a company
that generates the same total profit from one year to the next can report a
10% rise in its profit per share by buying back 10% of its shares. Unless the
buy-back occurs at a time when the company's assets are being substantially
under-priced by the stock market it cannot add long-term value because money
used in re-purchasing stock is money that cannot be used to expand/improve
the business; but it can certainly provide a boost in the short-term, which,
in many cases, is where the primary focus of senior management lies.
Again, though, the corporate rush to buy-back stock appears to be mostly a
US phenomenon and therefore doesn't really explain the persistent strength
in equities throughout the world.
The key, we suspect, lies in the inter-relationship between the US$, the euro
and the Yen. Equities have done well as the US$ has weakened relative to the
euro and as the Yen has weakened relative to the US$, which means that equities
have benefited as the Yen has become very weak relative to the euro. This relationship
has prevailed for more than two years, but over the past 11 months -- the period
covered by the following chart-based comparison of the S&P500 Index and
the euro/Yen exchange rate -- it has become stronger than ever.
Now, the tight positive correlation between the stock market and euro/Yen
evident on the following chart is not necessarily causal; however, it probably
is causal in that the borrowing (shorting) of Yen in order to buy the higher-yielding
euro -- a trade that pushes the euro upward against the Yen -- has been and
continues to be an important source of the liquidity elevating stock markets
throughout the world.

So, when assessing the risks for the broad stock market it probably makes
sense to focus on the potential for Yen strength against the euro rather than
on the potential for the Dollar Index to break below 80. The inter-market relationships
of the past year certainly suggest that substantial strength in the Yen versus
the euro would be more problematical for equities than would additional weakness
in the US$ against the euro; and in our opinion, a sharp rise in Yen/euro has
a much higher probability of occurring over the next few months than does a
major breakdown in the Dollar Index.
In a nutshell, equities have fared well as the US$ has weakened relative to
the euro and as the Yen has weakened relative to the US$ (resulting in substantial
weakness in the Yen relative to the euro). The worst case as far as the short-term
prospects for global equities are concerned, therefore, would probably entail
US$ strength relative to the euro and Yen strength relative to the US$.
