Risk
management is an essential but
often overlooked prerequisite to successful active trading. After all, a trader
who has generated substantial profits over his or her lifetime can lose it all
in just one or two bad trades if proper risk management isn't employed. This
article will discuss some simple strategies that can be used to protect your
trading profits.
Planning
Your Trades:
Successful
traders commonly quote the phrase: "Plan the trade and trade the plan."
Just like in war, planning ahead can often mean the difference between success
and failure. Stop-loss (S/L) and take-profit (T/P) points represent two key ways in
which traders can plan ahead when trading. Successful traders know what price
they are willing to pay and at what price they are willing to sell, and they
measure the resulting returns against the probability of the stock hitting
their goals. If the adjusted return is high enough, then they execute the
trade. Conversely, unsuccessful traders often enter a trade without having any
idea of the points at which they will sell at a profit or a loss. Like gamblers
on a lucky or unlucky streak, emotions begin to take over and dictate their
trades. Losses often provoke people to hold on and hope to make their money
back, while profits often entice traders to imprudently hold on for even more
gains.
Stop-Loss
and Take-Profit Points
A stop-loss point is the price at which a trader will sell a stock and take a
loss on the trade. Often this happens when a trade does not pan out the way a
trader hoped. The points are designed to prevent the "it will come
back" mentality and limit losses before they escalate. For example, if a
stock breaks below a key support
level, traders often sell as soon as possible. On the other side of the table,
a take-profit point is the price at which a trader will sell a stock and take a
profit on the trade. Often this is when additional upside is limited given the
risks. For example, if a stock is approaching a key resistance level after a large move upward, traders may
want to sell before a period of consolidation takes place.
How to
Effectively Set Stop-Loss Points
Setting stop-loss and take-profit points is often done using technical
analysis, but fundamental analysis can also play a key role in timing. For
example, if a trader is holding a stock ahead of earnings as excitement builds,
he or she may want to sell before the news hits the market if expectations have
become too high, regardless of whether the take-profit price was hit.
Moving averages represent the most popular way to set these points, as they
are easy to calculate and widely tracked by the market. Key moving averages
include the five-, nine-, 20-, 50-, 100- and 200-day averages. These are best
set by applying them to a stock's chart and determining whether the stock price
has reacted to them in the past as either a support or resistance level. Another
great way to place stop-loss or take-profit levels is on support or resistance trendlines. These can be drawn by
connecting previous highs or lows that occurred on significant, above-average
volume. Just like moving averages, the key is determining levels at which the
price reacts to the trendlines,
and of course, with high volume.
When setting
these points, here are some key considerations:
- Use
longer-term moving averages for more volatile stocks to reduce the chance that
a meaningless price swing will trigger a stop-loss order to be executed.
- Adjust
the moving averages to match target price ranges; for example, longer
targets should use larger moving averages to reduce the number of signals
generated.
- Stop
losses should not be closer than 1.5-times the current high-to-low range
(volatility), as it is too likely to get executed without reason.
- Adjust
the stop loss according to the market's volatility; if the stock price
isn't moving too much, then the stop-loss points can be tightened.
- Use known
fundamental events, such as earnings releases, as key time periods to be
in or out of a trade as volatility and uncertainty can rise.
Calculating Expected Return
Setting stop-loss and take-profit points is also necessary to calculate expected return. The
importance of this calculation cannot be overstated, as it forces traders to
think through their trades and rationalize them. As well, it gives them a
systematic way to compare various trades and select only the most profitable
ones.
This can be
calculated using the following formula:
[ (Probability of Gain)
x (Take Profit % Gain) ] + [ (Probability of Loss) x (Stop Loss % Loss) ]
The result
of this calculation is an expected return for the active trader, who will then
measure it against other opportunities to determine which stocks to trade. The
probability of gain or loss can be calculated by using historical breakouts and breakdowns from the support or
resistance levels; or for experienced traders, by making an educated guess.
The Bottom
Line
Traders should always know when they plan to enter or exit a trade before they
execute. By using stop losses effectively, a trader can minimize not only losses, but also the
number of times a trade is exited needlessly. Make your battle plan ahead of
time so you'll already know you've won the war.
