To steal a page from the
late Broadway belter (beltress?) Ethel Merman, "There's no
business like no business." Internet firms with no revenues and
no earnings are late arrivals to this party; the global foreign
exchange business pioneered the concept of fast and furious
trade for no purpose other than to trade fast and furiously.
Real goods, real services and real earnings just get in the way.
Foreign exchange trading became the world's largest business -
about $1.2 trillion in daily transaction volume - only after it
shed its dowdy connection to underlying physical trade and
became an interest rate arbitrage play following the advent of
floating exchange rates in the early 1970s.
Modern options theory is
a contemporary of floating exchange rates; the original
Black-Scholes model was published in 1973, and important
extensions by Robert Merton and others followed in quick
succession. With so much money at stake and so many theoretical
and computational advances cascading, banks and trading firms
quickly engaged in an arms race to gain a fleeting edge.
The connection between
fancy footwork and profitable trading is tenuous at best, and
one can be excused for suspecting many of the latest forays into
hyper-sophistication as a way of separating the priestly classes
from the riff-raff. Still, traders cannot play the game anymore
at any level without at least acquainting themselves with all of
the tools of the trade.
This compact volume is a
great place to start this acquaintance for newbies and an
excellent reference to keep on hand for veterans. David DeRosa,
a professor at Yale University's School of Management and a
regular contributor to Bloomberg News, conducts a brilliantly
concise tour of his world, including a description of currency
trading operations and mechanics seldom introduced into any
academic tome.
The inclusion of a
section on currency futures and exchange-traded options, while
necessary perhaps for the sake of completeness, seems almost
quaint in light of the dwindling role these instruments play for
all except the smallest speculators. Given the seminal role of
currency futures as the first futures on financial products of
any kind, this is a sad epitaph.
Chapters follow quickly
and concisely on plain vanilla options pricing, on volatility,
and on the differences between European and American options in
the foreign exchange market. Two concluding chapters on barrier
options and a small selection of non-barrier exotic options
(average rate, basket, quantos and compound options) complete
the text.
The reader, if anything,
is left wanting to see more examples of this quality and
clarity. An expanded discussion of what additional information a
foreign exchange trader must deal with during the day - interest
rates, commodity prices, stock market fluctuations, political
flatulence - and how these might affect the market would
increase this work's "handbook" value. An expansion to include
chapters on when to use which exotic option, why and what the
costs and risks of these options are would be welcomed as well.
And, while the euro was too new at the time of this book's
writing, further discussion of and speculation on this grand
experiment would have been welcome.
The true economic cost
of training a trader should be enough to make any trading firm
weep. Including this book in any package of materials or
training session would be a cost-effective move indeed.
