T h e crash o f 2 008 crushed “real m oney” investors (end ow m ents, pensions, fo u n d atio n s, an d fam ily offices).
W orld m arkets— from real estate an d equities to co m
m odities an d credit— collapsed. Som e o f the w o rld ’s
m ost venerable financial in stitu tio n s disappeared, w hile
m any hedge fu n d , private equity, venture capital, an d
real asset m anagers suffered im m ense losses. Yet, th e
w orld has n o t en d ed , an d now, all investors m ust adapt
to th e new reality.
A nalyzing m oney m anagers w ho fared well in 2 0 0 8 —
eith er by p o stin g stro n g p erform ance or by preserving
capital— is a logical startin g p o in t. G lobal m acro hedge

Q
uestion: W hat is the difference between a Peruvian peasant tanner
and a Harvard or Yale endow m ent manager?
Answer: T he peasant is the one w ho understands risk-sensitive investing
and sound investment goals.
T hat question and answer illustrate why I, as a mere impractical
academic historian, find the practical world o f investment fascinating.
I got my first peek into the m ystery-w rapped w orld o f hedge funds
several years ago, w hen Steven Drobny invited me to give the opening
address at his annual conference for hedge fund managers. That initial
peek aroused my curiosity. It led me to return to his conference in the
following year as an observer, to m eet some o f Stevens colleagues and invited managers, to read Steven’s previous book, Inside the House o f Money,
and to enjoy brunches with Steven from tim e to time, where we talk
about anything from hedge funds and raising children to fixing the world.
O ne reason why I became fascinated in the world o f investing was
the parallels that I saw betw een investing and history. T he issue o f risk
is acute in both o f those spheres. Endow m ent and hedge fund managers

evaluate upside and downside risk to the m oney they manage for other
people, and they make or lose m oney as a result o f those evaluations. T he
historical and m odern peoples w hom 1 study assess upside and downside
risk to their ow n resources that they manage, and they and their families
survive or die as a result o f those evaluations.
For example, in the M iddle Ages, the N orse on the island ot G reenland, descended from Viking settlers w ho colonized G reenland in the
year AD 984, made decisions each year about how many o f their cows
to cull in the fall. They knew the am ount o f hay that they had harvested
during the previous summer, and knew the length o f each individual
w inter (hence the dem and for hay to feed the cows over the w inter)
over many past decades, but did not know the length o f the particular
w inter lying ahead. If they still had hay left in the spring, that m eant that
they had culled a certain unnecessary quantity o f cows, and they could
have brought m ore cows through the winter, then produced m ore milk,
cheese, and meat as a result and been less hungry the following year.
If they instead found themselves running out o f hay during the w inter,
that m eant they had culled too few cows in the fill, m eaning they w ould
have to start sacrificing cows in the w inter, ending up w ith fewer cows
in the spring than if they had culled m ore cows already in the fall.
For about 376 years, the G reenland N orse made those annual decisions about risk-sensitive investment in cow herds sufficiently well that
they flourished. But around year AD 1360 there was a particularlv cold
series o f winters for w hich their hay gamble proved to be a bad miscalculation, w ith the result that all their cows died during one w inter,
and all o f the thousand or so N orse o f G reenland’s W estern Settlem ent
starved to death in the late winter. H edge fund managers will u n d o u b tedly empathize w ith the dilemma that the N orse faced, and w ith their
tem ptation to be greedy and to invest in m any cows in their w inter herd.
But managers will be grateful, w hen their own risk calculations prove
to be in error, that they themselves lose only their investors' m onev and
don't lose their own lives.
A nother reason why I was fascinated w ith w hat I learned about
the world o f investments was the parallels betw een investm ent m anagers
and m odern farm ing peoples. For instance, studies o f m odern Peruvian
peasants resolved a mystery that long puzzled medieval historian', and
that should have puzzled college investment managers. Each medieval

Fo re w o rd xi
peasant family didn’t cultivate one large plot o f ground; instead, they
cultivated up to several dozen little strips o f land scattered in several
different directions from their hut, despite the obvious inefficiency o f
wasting time on traveling and carrying supplies betw een strips, as well
as the waste o f land inevitably left uncultivated at boundaries betw een
adjacent strips belonging to different peasants. A possible explanation
for the peasants’ apparently irrationally stupid behavior was that they
were practicing the virtue o f diversification praised by m odern financial
managers: d o n ’t put all your eggs in one basket but instead diversify your
portfolio. In any given year, all the strips in a single field may fail because
o f pest infestation, local climate, or thieves. You (the peasant family) are
less likely to starve if you plant different scattered strips.
T hat idea o f diversification is plausible, but only recently did economic historians and agronomists discover how sophisticated are the
underlying calculations perform ed unconsciously by peasants. M odern
Peruvian peasants scatter their strips o f land as did medieval English peasants. Any individual Peruvian peasant owns betw een 9 and 26 different
strips, whose yields o f potatoes and other crops vary from year to year
independently o f each other and partly unpredictably. T he peasants can’t
store significant quantities o f potatoes from one year to the next; their
food needs have to be satisfied by the current year’s harvest. In analogy to
the medieval N orse farm ers’ need for hay, the m odern Peruvian peasants
must succeed in obtaining a certain m inim um potato harvest am ounting
to about 680,000 calories in every single year, otherwise they and their
families end up starving. For 20 different peasants ow ning a total o f 488
strips, the anthropologist Carol Goland measured the potato yields in
successive years, then used those measured years to calculate the yield
that each peasant w ould have harvested each year by cultivating only 1,
or 2, or 3 . . . etc. strips, w ith total area held constant but with yield per
acre equal to the value for each possible com bination o f the 1, 2, 3 etc.
actual strips. She also measured the calories invested in travel betw een
1, 2, 3 . . . strips, in order to obtain the net calories remaining to the
peasant for each com bination.
Four interesting conclusions em erged from G oland’s study. First,
the long-term time-averaged potato harvest decreased with subdivision
o f the peasant's land, in agreem ent with the expectations o f horrified
western agronomists w ho urged the peasants to consolidate their strips.

xii FOREWORD
and for several reasons including wasted travel time. Second, the year-toyear variance in potato harvest decreased with increasing subdivision o f
the peasant’s land, as expected from the principle "don't put all your eggs
in one basket " But, because o f that variance, the third conclusion was
that the frequency o f the years with a harvest so low as to cause starvation
was highest for a single strip and decreased with subdivision to reach zero
at a certain num ber o f strips varying betw een 4 and 13, depending on
the particular peasant's land. Finally, each individual peasant planted 2 or
3 strips m ore than the num ber required to reduce the risk o f starvation
to zero.
In short, the peasants do not aim at m axim izing long-term tim eaveraged yield, even though that is an appropriate goal for investors
not spending their earnings and just investing to pay for luxuries on
a rainy day in the distant future. Instead, the peasants only maxim ize
long-term yield insofar as that is consistent w ith their overriding goal
o f elim inating their risk o f starving in any given year, and throw ing in a
small safety m argin for that calculation. It seems to m e that the Harvard
and Yale endow m ent managers are in a position analogous to that of
the peasants, and w ould have done better to set a goal o f m axim izing
yield only above a certain minim al level. As a Harvard graduate myself,
I receive my college's periodic mailings, the tone o f w hich has recently
changed from pride in Harvard's wisdom to tales o f woe. Harvard, like
Peruvian peasants, uses endow m ent incom e for current needs: in fact, as
it turns out. a considerable fraction o f college expenses is paid from the
endow m ent each year. As a result. Harvard has had to impose a hiring
freeze, and recently it had to cancel its plan tor a new science campus.
Naturally, Peruvian peasants did not perform the sophisticated statistical analysis that Carol Goland perform ed retrospectively. Instead, they
arrived at their solution o f optim izing strip num bers to avoid starvation
on the basis o f long experience. They had observed some greedy but
lazy peasants w ith overconsolidated holdings w ho glutted themselves for
m any years, only to starve to death in a bad year. Likewise, thev observed
other peasants w ith overspread holdings w ho never starved but also never
glutted, while still others discovered a happy m edium o f strip num bers
that perm itted frequent modest gluts and never any starvation. Should
vou suspect that the peasants really did use a pocket calculator and a
friendly visiting m athematical modeler, birds such as sparrows, w hich

certainly don’t have pocket calculators, also make similar risk-sensitive
decisions such that they are never starving.
Steven D robny’s latest book is about the Peruvian peasants o f the
hedge-fund world: that m inority o f managers w ho made m oney or at
least preserved capital during the A nnus horribilis o f 2008, while greedier
managers w ho had accumulated major gluts and perhaps even achieved
higher long-term time-averaged returns in previous happy years lost
disastrously or w ent bankrupt. Hence, anyone interested in the world
o f finance and m aking m oney will pour over this book to extract some
powerful lessons: W hat can I do to emulate those successful guys and
gals in order to make m oney or preserve capital, even under the worst
conditions, and becom e rich and famous?
But this book will also fascinate anyone interested in people. My
other interest in the hedge fund world is for that reason. W hen Steven
Drobny introduced me to his world o f colleagues and clients, 1 found
myself com paring them with the many creative scientists, architects,
composers, artists, and business people w hom 1 have interviewed. I
wondered: W hat makes these people tick? H ow did their childhood
experiences shape their adult professional success? Because a person’s
abilities change with age, do most hedge fund managers becom e washed
up by age 40, or does a 60-year-old m anager still have ways o f succeeding
in a world o f cutthroat young managers w ho need less sleep and w ho
received a m ore recent technological education? Are they managing
m oney in order to becom e rich, to stoke their ego, to acquire flashy cars
and superm odel dates, or to satisfy some other motivation?
W ith Steven D robny’s kind help, I interview ed some hedge fund
managers (including a couple that Steven interviewed for this book)
just for my ow n curiosity. I was struck by the fact that, although all
the managers were quite different from each other, each had a broader
life philosophy that he or she applied to the w orld o f hedge funds in
particular. Each had childhood experiences, things that their parents did
or didn’t do for them , that shaped them as future managers, although
their parents could have hardly anticipated that outcom e. All o f them
became managers partly for fun and curiosity. T hey want to understand
how the w orld works, and they want to keep testing their evolving
hypotheses about the world’s workings against reality. All are still active
in their 40s, 50s, and 60s. Yes, the 28-year-old whiz kids can get by with

x iv FOREWORD
less sleep, while saddled with less knowledge about dated technologies,
and have been schooled in the latest technologies. But “older" managers
w hom I interviewed enjoyed the advantage o f having used their years
to try out m ore things, and having seen more ups and downs. T hey are
in the position o f the peasant w ho remembers that dry sum m er 17 years
ago, and w ho isn’t deceived by the recent runs o f wet sum m ers into
assuming that sum m er will always be wet. Some o f the managers w hom
I m et expect still to be managing m oney w hen they are 80 years old.
They fulfilled their own lifetime financial needs long ago, but they may
never fulfill their curiosity about how the world works, nor the fun they
derive from testing their ideas.
My own interviews were casual ones, by an interview er (i.e., me)
ignorant o f the subject matter. Steven D robny’s book consists o f 13 long
interviews, eleven anonymous and two o f nam ed managers. N o one is
better qualified than Steven to probe the subject matter, and to place
his interviewed managers in a broad context, both as investors and as
hum an beings. W hether you are curious about m oney or people, you
are certain to love this book.
