Alexey Poyarkov,
a former gold-medal winner of the International Mathematical
Olympiad for high-school students, spent most of his early career honing
algorithms
at technology companies such as
Microsoft Corp.
, where he helped make the Bing search engine smarter at ferreting out pornography.
Last
year, a bidding war for Mr. Poyarkov broke out among hedge-fund
heavyweights Renaissance Technologies LLC, Citadel LLC and TGS
Management Co. When it was over, he went to work at TGS in Irvine,
Calif., and could earn as much as $700,000 in his first year, say people
familiar with the contract.
The Russian-born software engineer, who declined to comment,
as did the hedge funds, had almost no financial experience. What TGS
wanted was his wizardry at designing algorithms, sets of rules used to
power calculations and problem-solving, which in the investment world
can quickly parse data and decide what to buy and sell, often with
little human involvement.
Up and down Wall Street, algorithmic-driven trading and the
quants who use sophisticated statistical models to find attractive
trades are taking over the investment world.
On many trading
floors, quants are gaining respect, clout and money as investment firms
scramble to hire mathematicians and scientists. Traditional trading
strategies, such as sifting through balance sheets and talking to
companies’ customers, are falling down the pecking order.
“A decade ago, the brightest graduates all wanted to be
traders at Wall Street investment banks, but now they’re climbing over
each other to get into quant funds,” says
Anthony Lawler,
who helps run quantitative investing at
GAM Holding AG
. The Swiss money manager last year bought British
quant firm
Cantab Capital Partners for at least $217 million to help it expand into computer-powered funds.
Guggenheim
Partners LLC built what it calls a “supercomputing cluster” for $1
million at the Lawrence Berkeley National Laboratory in California to
help crunch numbers for Guggenheim’s quant investment funds, says
Marcos Lopez de Prado,
a Guggenheim senior managing director. Electricity for the
computers costs another $1 million a year.
Algorithmic trading
has been around for a long time but was tiny. An article in The Wall
Street Journal in 1974 featured quant pioneer
Ed Thorp.
In 1988, the Journal profiled a little-known Chicago
options-trading firm that had a secret computer system. Journal reporter
Scott Patterson wrote a
best-selling book in 2010 about the rise of quants.
Prognosticators
imagined a time when data-driven traders who live by algorithms rather
than instincts would become the kings of Wall Street.
That day has arrived. In just one sign of their power,
quantitative hedge funds are now responsible for 27% of all U.S. stock
trades by investors, up from 14% in 2013, according to the Tabb Group, a
research and consulting firm in New York.
Quants have almost
caught up to individual investors, which outnumber quants and
collectively have 29% of all stock-trading volume.
At the end of
the first quarter, quant-focused hedge funds held $932 billion of
investments, or more than 30% of all hedge-fund assets, estimates HFR
Inc. In 2009, quant funds held $408 billion, or 25% of all hedge-fund
assets.
Quants got $4.6 billion of net new investments in the
first quarter, while the overall hedge-fund business saw withdrawals of
$5.5 billion.
The computers are outperforming humans at picking investments.
In the past five years, quant-focused hedge funds gained about 5.1% a
year on average. The average hedge fund rose 4.3% a year in the same
period.
In the first quarter, quant funds rose about 3%, compared with 2.5% for the average hedge fund.
Quants
have been helped by two transformative forces. Regulatory scrutiny has
made it hard for investors to obtain an edge through methods such as
prodding company executives for information or tapping expert networks
that included employees of public companies.
Even more importantly, investors now have at their fingertips an expanding ocean of
data about the global economy and financial data, such as changes in earnings estimates and accounts receivable.
The next frontier: tapping data from drones and other
cutting-edge sources to help understand companies and the economy in
real time.
Quants are different from high-frequency traders, who
tend to focus on very short-term trades that might last just
milliseconds. High-frequency traders have been under pressure as market
volatility dips and competition grows.
Exchange-traded funds also use algorithms but are geared more to investors who want exposure to certain industries or sectors.
Quantitative-driven
trades can last anywhere from a few minutes to a few months. The
biggest quant firms, including Renaissance, Two Sigma Investments LLC,
D.E. Shaw Group, PDT Partners and TGS, make thousands of trades and
manage tens of billions of dollars in investor assets.
Some
analysts worry that firms and investors stampeding into the quant
business might be disappointed. The most successful quants have been
operating for years. And hiring Ph.D.s doesn’t guarantee profits.
More
competition could hurt returns and give a false sense of security about
the market’s stability. In 2007, what became known as the “quant
meltdown” was caused largely by the similarity of strategies among
quants, who simultaneously rushed to sell, causing losses at other firms
and more selling.
Mathematician
William Byers,
who wrote the 2010 book “How Mathematicians Think,” warns that
rendering the world in numbers can give investors a deceptive belief
that predictions churned out of computers are more reliable than they
truly are. The more investors flock to complicated algorithmic models,
the more likely it is some algorithms will be similar to one another,
possibly fueling larger market disruptions, some analysts say.
So
far, though, nothing has stopped the quant arms race, which is creating
new jobs previously unheard of in the finance industry.
Citadel,
of Chicago, has a chief scientist to run its analytics and quantitative
strategies. Balyasny Asset Management LP hired in August data scientist
Gilbert Haddad,
formerly of
Schlumberger Ltd.
and
General Electric
Co.
, to overhaul data and analytics at the New York hedge-fund firm.
He studied nanoparticles at the University of Wisconsin and has a Ph.D.
in engineering.
“You take tours of offices, and everyone is always
pointing out some guy off in a corner, working on his own,” says
Alexandru Agachi,
chief operating officer at Empiric Capital Ltd., a startup quant
hedge fund in London. “They say with pride: ‘Over there is our quant.
He’s building signals.’ ”
It’s common for hedge funds to retool
themselves to fit the latest popular strategy. Many funds dove into
mortgages after the financial crisis ebbed. Some turned into “macro”
investors in anticipation of global economic shifts.
Hedge-fund billionaire
Steven A. Cohen’s
investment firm, Point72 Asset Management, with $12 billion in
assets, is shifting about half of its portfolio managers to what it
calls a “man plus machine” approach.
Teams that use old-school
research methods are working alongside data scientists. Financial
analysts are taking evening classes to learn data-science basics.
Point72 is plowing tens of millions of dollars into a group that
analyzes reams of data, including credit- card receipts and foot traffic
captured by apps on smartphones. The results are passed on to traders
at the Stamford, Conn., investment firm.
Point72 lost money in
most of its traditional trading strategies last year, say people
familiar with the results. The firm’s quant investors made about $500
million.
Matthew Granade,
Point72’s chief market-intelligence officer, recently encouraged
London School of Economics students to learn basic programming
languages, like
R
and
Python,
to become more competitive when they graduate. Investors are shifting their preference from “artisan to engineer,” he said.
Billionaire
Paul Tudor Jones
is one of the best-known investors in history. The former cotton
trader anticipated the 1987 stock-market crash and made gigantic profits
with quick bursts of trading, averaging annual gains of more than 17%
since then. His hedge-fund firm, Tudor Investment Corp., barely made any
money in 2014 and 2015, though.
By last year, Mr. Jones was
feeling pressure from more successful quant traders, according to people
close to the firm. In October, Mr. Jones chose
Dario Villani,
an Italian with a doctorate in theoretical physics who was hired
in 2015, to help rejuvenate Tudor.
Hunkered down with a team of
quants and other Tudor employees in a small house on an estate in
Greenwich, Conn., Mr. Villani began developing computer programs to
replicate trading positions of Tudor’s portfolio managers using
instruments that better allow the firm to increase risk to improve
returns without endangering the hedge fund or Tudor, people familiar
with the matter say.
Despite the changes, Tudor’s two key funds were flat in 2016 as well as so far this year, even as markets have climbed.
Humans
have long searched relentlessly for ways to gain an information edge.
Legend has it that financier Baron Rothschild built a network of field
agents and carrier pigeons in 1815 to get a jump on the Battle of
Waterloo outcome. Today’s quants hope to digest—and act on—economic and
corporate information faster than traditional investors.
Hedge funds with quant-focused strategies have been poring
over private Chinese and Russian consumer surveys, illicit
pharmaceutical sales on the dark web—a network of websites used by
hackers and others to anonymously share information—and hotel bookings
by U.S. travelers, according to Quandl Inc., a platform for such data.
In
the late 1990s, an algorithm might have simply tried to ride the
momentum of a stock’s price rise, buying at a certain price level and
selling at a predetermined moment. Today’s algorithms can make
continuous predictions based on analysis of past and present data while
hundreds of real-time inputs bombard the computers with various signals.
Some investment firms are pushing into
machine learning,
which allows computers to analyze data and come up
with their own predictive algorithms. Those machines no longer rely on
humans to write the formulas.
Algorithms and quants eventually
could sharply reduce the need for large investment staffs. A
machine-driven algorithm might help quantitative researchers discover
dozens of new algorithms in the time it used to take to create one.
In
the battle for talent, quant-focused firms often are reluctant to call
themselves hedge funds or even investment firms. Quant firms would
rather emphasize their similarities to cutting-edge tech companies in
Silicon Valley.
Two Sigma, based in New York, has in-house hacker
labs, robotics competitions and game rooms. Empiric calls itself a
“technology company operating in financial markets.”
Saeed Amen,
a quantitative researcher in London, says his investment
strategies were considered “very niche” for most of his 14-year career.
He
organized social events for quants, including occasional gatherings of a
group called the Thalesians after ancient Greek geometer Thales of
Miletus. The beer and conversation sometimes attracted fewer than a
dozen people.
Mr. Amen’s phone has started ringing with calls
from hedge-fund managers in the U.S. and Europe. They don’t all want
automated investing algorithms, but they are trying to figure out how to
make better predictions, he says.
Much of that push is coming
from investors such as Pepperdine University in Malibu, Calif. Last
year, the college placed about 10% of its $750 million portfolio in big
quant funds, including those run by
Man Group
PLC of London and AQR Capital Management LLC, Greenwich, Conn.
Until
then, Pepperdine had “essentially zero” quant investments, says
Michael Nicks,
its director of investments. “The narrative of fundamental
investing is much more comfortable to digest,” he says. “Finding a
company with good prospects makes sense, since we look for undervalued
things in our daily lives, but quant strategies have nothing to do with
our lives.”
After “years and years of self-education” and dozens
of meetings with quant managers, says Mr. Nicks, Pepperdine decided it
was ready to make the leap.
