THE STRIKING PRICE
Traders and investors should attempt to be
liquidity providers, not consumers, and use
strategies common to market makers.
When Markets Are Wild,
Embrace Liquidity
L
iquidity is a fickle companion.
Seemingly ubiquitous under most
circumstances, it has a way of be-
coming scarce when most needed.
The recent wild gyrations in markets—in-
cluding in stocks and options—have caused
many traders to reassess their assumptions
about liquidity. In the current environment,
traders and investors should attempt to be
liquidity providers, not consumers, and use
strategies common to market makers.
The dictionary definition of liquidity is
“the availability of liquid assets to a market
or company.” That definition, however,
refers to corporate and personal balance
sheets and is a poor explanation of market
liquidity. In financial markets, liquidity is
better understood to be the ease with which
an asset can be traded with little effect on its
price. Liquid markets show large bid and
ask sizes at tight spreads, making it simple
for traders to buy and sell their desired secu-
rities or derivatives with little price impact.
There is a nasty feature of liquidity that
has revealed itself over the past few weeks:
It is often inversely proportional to volatility.
This is a direct result of how market makers
operate. Market makers are traders who
commit to post continuous bid and ask
prices in their assigned products, and thus
are key providers of liquidity. They implic-
itly agree to be subject to negative selection—
in other words, doing the trades that others
initiate—in exchange for a better chance at
capturing bid/ask spreads.
Every financial transaction needs to bal-
ance risk and reward, and market makers
must strike that balance countless times a
day. Realizing that every one of their posted
bids and offers could lead to a trade, market
makers use a calculus that optimizes the
capital they are willing to commit.
When markets are functioning normally,
it is relatively easy for market makers to be
confident that their prices are reasonable,
and that undesirable or risky positions can
be reversed or hedged with little difficulty.
By “normal,” we mean that prices move
somewhat continuously in modest trends,
with relatively balanced trading between
bid and ask prices. If the order flow be-
comes overwhelming in one direction or
another, it changes the risk/reward calculus.
What is the market maker’s strategy in
such a situation? Many years ago, before this
was fully programmed into our models, we
had a big sign in our trading room remind-
ing us what to do when markets turned ugly:
- Widen quotes, 2) Shrink sizes, and 3)
Raise volatilities.
This is what market makers do in dis-
jointed markets, and what you should do, as
well. You can accomplish that by trading
smaller sizes and demanding more profit for
each of your trades. If you normally trade 10
options contracts, trade fewer. Don’t be he-
roic when prices are moving rapidly in one
direction or another. Successful market
makers are very disciplined about taking
profits and losses, and, while every options-
market participant should be keenly aware
of risk and reward, volatile markets require
exceptional vigilance.
Now is the time when you can be the one
who is paid to add liquidity by using limit
orders inside the posted quote. Rapidly mov-
ing markets usually feature wider bid/ask
spreads and/or smaller posted sizes. Small
investors and traders should avoid hitting
bids or lifting offers that cross large posted
spreads, along with market orders, which
should be avoided entirely, since they con-
sume liquidity. When you set the bid or of-
fer, you are providing liquidity. You benefit
from others crossing the spread to trade
with you at your chosen price.
And by all means, avoid consuming li-
quidity by being forced into trades to cover
margin calls. It is safer to eschew margin
borrowing in volatile markets. An adage
states, “Trade when you can, not when you
have to.” Thinking and acting like a market
maker can help you meet that goal.B

Skew indicates whether the options market expects a stock-market advance or decline. It measures the difference
between the implied volatility of puts and calls that are 10% out of the money and expire in three months. Higher
readings are bearish.
