It has been said that the single most important factor
in building equity in your trading account is the size of the position you take
in your trades. In fact, position sizing will account for the quickest and most
magnified returns that a trade can generate. Here we take a controversial look
at risk and position sizing in the forex market and give you some tips on how
to use it to your advantage.
The Undiversified Portfolio
In the book "The Zurich Axioms" (2005), author
Max Gunther states that in order to break away from the "great
un-rich," an investor must avoid the temptation of diversification. This
is controversial advice, since most financial advice encourages investors to
diversify their portfolios to ensure protection against calamity.
Unfortunately, nobody gets rich from diversification. At best, diversification
tends to balance winners with losers, thus providing a mediocre gain.
The author goes on to say that investors should
"keep all [their] eggs in just one or two baskets" and then
"look after those baskets very well". In other words, if you are to
make real headway with your trading, you will need to "play for meaningful
stakes" in those areas where you have sufficient information to make an
investment decision.
To measure the relevance of this concept, one need only
to look at two of the most successful investors in the world, Warren Buffet and
George Soros. Both of these investors do play for meaningful stakes. In 1992,
George Soros bet billions of dollars that the British pound would be devalued
and thus sold pounds in significant amounts. This bet earned him more than $1
billion virtually overnight. Another example is Warren Buffet's purchase of
Burlington Railroad for $26 billion - a significant stake to say the least. In
fact, Warren Buffett has been known to scoff at the notion of diversification,
saying that "it makes very little sense for those who know what they are
doing."
High Stakes in Forex
The forex market, in particular, is a venue where large
bets can be placed thanks to the ability to leverage positions and a 24-hour
trading system that provides constant liquidity. In fact, leverage is one of
the ways to "play for meaningful stakes". With just a relatively
small initial investment, you can control a rather large position in the forex
markets; 100:1 leverage being quite common. Plus, the market's liquidity in the
major currencies ensures that a position can be entered into or liquidated at
cyber speed. This speed of execution makes it essential that investors also
know when to exit a trade. In other words, be sure to measure the potential
risk of any trade and set stops that will take you out of the trade quickly and
still leave you in a comfortable position to take the next trade. While
entering large leveraged positions does provide possibility of generating large
profits in short order, it also means exposure to more risk.
How Much Risk Is Enough?
So just how should a trader go about playing for
meaningful stakes? First of all, all traders must assess their own appetites
for risk. Traders should only play the markets with "risk money,"
meaning that if they did lose it all, they would not be destitute. Second, each
trader must define - in money terms - just how much they are prepared to lose
on any single trade. So for example, if a trader has $10,000 available for
trading, he or she must decide what percentage of that $10,000 he or she is
willing to risk on any one trade. Usually this percentage is about 2-3%.
Depending on your resources, and your appetite for risk, you could increase
that percentage to 5% or even 10%, but I would not recommend more than that.
Five Chart Patterns you need to know…
So playing for meaningful stakes then takes on the
meaning of managed speculation rather than wild gambling. If the risk to reward
ratio of your potential trade is low enough, you can increase your stake. This
of course leads to the question, "How much is my risk to reward on any
particular trade?" Answering this question properly requires an
understanding of your methodology or your system's "expectancy".
Basically, expectancy is the measure of your system's reliability and,
therefore, the level of confidence that you will have in placing your trades.
Setting Stops
To paraphrase George Soros, "It's not whether you
are right or wrong that matters, but how much you make when you are right and
how much you lose when you are wrong."
To determine how much you should put at stake in your
trade, and to get the maximum bang for your buck, you should always calculate
the number of pips you will lose if the market goes against you if your stop is
hit. Using stops in forex markets is typically more critical than for equity
investing because the small changes in currency relations can quickly result in
massive losses.
Let's say that you have determined your entry point for
a trade and you have also calculated where you will place your stop. Suppose
this stop is 20 pips away from your entry point. Let's also assume you have
$10,000 available in your trading account. If the value of a pip is $10,
assuming you are trading a standard lot, then 20 pips is equal to $200. This is
equal to a 2% risk of your funds. If you are prepared to lose up to 4% in any
one trade, then you could double your position and trade two standard lots. A
loss in this trade would of course be $400, which is 4% of your available
funds.
The Bottom Line
You should always bet enough in any trade to take
advantage of the largest position size that your own personal risk profile
allows while ensuring that you can still capitalize and make a profit on
favorable events. It means taking on a risk that you can withstand, but going
for the maximum each time that your particular trading philosophy, risk profile
and resources will accommodate such a move.
An experienced trader should stalk the high probability
trades, be patient and disciplined while waiting for them to set up and then
bet the maximum amount available within the constraints of his or her own
personal risk profile.
