The
financial market in the United States includes both cash and
derivative markets, such as future and option markets. All
kinds of products, ranging from grains to equities, and from
oil to bonds, are traded in those markets.
In
each market, there are participants with different objectives.
Some look for long-term capital gains, some want to hedge
their real positions, and still others try to make profits
out of short-term price fluctuations. The concept of market
making arises from such a market environment.
I.
What is market making?
Market
making means that a trader or a company puts both buy and
sell orders into the market, and wait for people to trade
with him on either sides. In every market, price is quoted
with both a bid and an offer price, with the latter a little
bit higher than the former. Ordinary traders and investors
"take the market," buying at offer price and selling
at bid price. However, market makers could sell at offer price
and buy at bid price. For example, imagine that the last price
of XYZ stock is 10.00 and a market maker puts a 9.90 buy order
and a 10.10 sell order into the market simultaneously. If
someone hits him by selling at his buying price of 9.90, he
gets a long position. If he thinks that the price of XYZ stock
would rise further, he would hold the position for a while
and square it at a higher price. If he is neutral or even
bearish, he may sell the stock right away. If the price in
the next second is 9.92 Bid/ 9.95 Offer, he may make the market
again by putting a sell order at 9.95 and wait for somebody
to buy from him, or just sell at 9.92 to take the market.
Market makers trade from market fluctuation to make money.
They like volatile rather than one-sided markets. If the market
keeps rising or falling, they will run into the problem of
taking positions that are against most people. Market makers
don't care much about the long-term trend, or fundamentals,
but focus on the short periods of abnormal price movement.
They trade hundreds or even thousands of round-turns every
day, and accumulate small gains into big profits.
Recently,
more and more automatic trading systems have come into the
scene. Usually, market makers have a "seat" in an
exchange, which is a kind of membership through which they
can enjoy lower commission and faster access to the market.
As electronic trading becomes more popular, it will replace
the conventional exchange-based out-cry market. The out-cry
market is the traditional market where traders stand in the
pit and trade with each other through hand signals and out-cries.
EUREX, the electronic trading system for European futures
products, has shown great success and has become the number
one futures exchange within just one year of its launch. Internet
stock trading has also attracted a lot of people due to its
low commission rates. In the electronic world, market makers
are most welcome, since they provide greater liquidity to
the market and make price moves smoother. In some equities
electronic trading systems, such as Archipelago and Island,
market makers can even receive commissions for each act of
market making.
Though
market makers get some advantages over ordinary investors,
they also have more obligations. Many exchanges require that
market makers give price quotes in all kinds of markets, even
when all the market participants want to trade the same way.
From this angle, market makers serve as a lubricant for the
market, as they absorb the extremely choppy price movement.
In
the world of market making, "edge" is a key word.
In the phrase "grasp the edge," edge means the difference
between a security's real market price and its fair value.
The task for market makers is to judge how much an edge would
bring them both trading opportunities and profits. There are
a lot of models and systems by which to judge the optimal
edges. For example, if Cisco releases earning reports that
are better than expected, market participants would jump into
the market to buy Cisco stocks. Market makers would try to
judge whether Cisco's stock price has risen too high in the
most recent minutes through some fair-value models or chart
analysis. If they believe that the price has been pushed high
enough to justify a short-time retreat, they would begin to
put sale orders into the market-with hopes that other traders
would buy at their prices-and then square their short positions
as soon as the expected retreat comes.
II.
Equity index futures market in the U.S.
In the United States, market-making activities exist in all
kinds of markets, especially in the market for futures. Chicago
is the center of U.S. futures market. People trade commodities
as well as financial futures here, among which equity index
futures and U.S. treasury futures are the most active. The
equity index future is a future contract based on the equity
index, such as S&P 500, NASDAQ, and Dow Jones indices.
It is calculated by adding the cost of carry, which is equal
to the interest, and then subtracting the dividends payment
from the current stock index. It is the best estimate of the
future stock index, and provides great hedging and trading
opportunities.
When
a significant event happens, people enter the futures market
first to buy or sell the index futures, and then the stock
market follows. For example, at the time when Microsoft waited
for the court decision on its anti-trust case, the trading
of its stock was halted. When the decision came out, and while
the trading of its stock was still suspended, people rushed
into the NASDAQ future market to hedge their positions on
Microsoft. In the stock market, there are restrictions on
the short sale of stocks, and when the market is bearish,
people have fewer opportunities to hedge, except through selling
index futures, since the futures market treats buying and
selling equally.
In
the United States, the stock index futures market opens nearly
24 hours, except for a half an hour break. In contrast, the
stock market only opens from 9:30am to 4:00pm. Though there
is an off-hour market for stocks, only some big-name stocks
such as Microsoft and Cisco have liquidity during off-hours.
Therefore, if any pieces of news come out at night, investors
can trade index futures to hedge or speculate on those less
liquid stocks
Many
mutual fund managers use the index futures to manage their
customers' asset. For example, imagine that a fund manager
receives a call from a customer who would like to send him
two million dollars to invest in the stock market in one month.
However, the customer is quite bullish about the market, and
is afraid that he may have to pay higher prices to buy stocks
after one month. The fund manager can then buy one-month index
futures contracts to lock in the entering price. No matter
what happens, the customer can be guaranteed of the option
of buying the index, or the portfolio of the index component
stocks, at the price specified in the futures contracts after
one month.
In
1999, one of the best years for the U.S. stock market, statistics
show that nearly half of the stock investment funds could
not beat the return of the S&P500 index after the management
fees. That means, if you just bought the S&P500 index
future, and held it for the year, you would get more than
20% annual return without paying attention to selecting high-performance
stocks. Therefore, investment in the index futures is a very
cost-effective method.
Furthermore,
since the stock index is equivalent to the capital-weighted
average of component stocks, buying index futures is just
like buying a portfolio of the stocks but costs lower commission
fees. Therefore, trading index futures is a very efficient
way to trade the whole market.
III.
Should China have an equity index futures market?
China
desperately needs a stock index futures market to provide
an efficient hedging method for investors. A lot of Chinese
investors complain that the prices of their stocks get stuck
even when the market index rises because no "dealers"
("Zhuang Jia") actively trade their stocks. Under
such circumstances, if there were an index futures market,
these investors would be able to buy index futures to take
advantage of the bull market. Furthermore, when their stocks
hit the down-limit and they cannot stop loss on their stocks,
they could sell the index futures to approximately square
their positions.
However,
many people still remember the crash of the Chinese government
bond futures market. As two major financial institutions fought
with each other in the market, the prices of bond futures
were pushed much too far away from the prices of the underlying
bonds. Eventually, one of the institutions went bankrupt,
and many small investors incurred great losses. Actually,
there is a very efficient way to solve such problems. In every
futures exchange in developed countries, there is a committee
that is authorized to determine the close prices of futures
contracts. They fix not only the futures market close prices,
but also the cash market prices. When they believe that the
futures prices have gone too far away from the cash market
prices, they have the right to change the close price of futures
based on the cash market price. It is the futures close price
that determines the daily mark-to-market profit or loss on
each account. Therefore, no one can take advantage by manipulating
the futures price while disregarding the cash market price.
Furthermore, the committee could also set the futures contract
prices whenever an emergency arises. When the terrorist attacked
the World Trade Center in the morning of September 11th, both
index futures and some blue-chip stocks had been traded for
a period of time in the pre-opening market. The stock and
futures exchanges were forced to close after the tragedy.
Due to the event, the Chicago Mercantile Exchange (CME) committee
set the close price of the index futures on the 11th just
equal to that of the 10th, and disregarded the pre-session
trade activity. By doing so, the committee set up a fair beginning
price for every stock and for all the investors when the market
reopened later.
The
major concern for the Chinese government regarding opening
a futures exchange might be that the trading of futures is
very speculative and risky. However, there might be an alternative
way through which Chinese investors can take advantage of
index products. In the United States, there are two synthetic
stocks, QQQ and SPY, that are the cash stock version of NASDAQ
and S&P500 index futures. Investors can trade such synthetic
stocks as real one, thereby eliminating the need to use leverage
as with index futures. Therefore, the synthetic stocks are
more for hedging purposes than for speculative uses. So if
the index futures market is thought to be too risky, Chinese
stock market could establish two synthetic stocks that represent
the Shanghai and Shenzhen stock indices for investors to invest
in and to hedge their individual stock positions.
The
equity index futures market has proven to be both an effective
and an efficient supplement to the stock market. As Chinese
financial market develops, market making will become an important
part of its functions, and an equity futures market should
become an integral component.
