The quantity of units a trader invests in a certain deal is known as position size. The size of the trader’s account and their level of risk tolerance should be considered when choosing the right position size.
Position sizing describes how big a position is inside a certain portfolio or how much money an investor would trade. By determining how many units of a particular asset they can buy, investors can manage risk and optimize profits through the process of position sizing.
Position sizing is a key concept in almost all investing types, although it is most directly related to day trading.
When using proper position sizing, the optimal course of action is determined by considering three key factors:
A trader must ascertain his account risk prior to using the proper position sizing for a given transaction. Usually, a percentage of the capital is used to convey this. Generally speaking, fund managers take on less risk than this, and most individual investors risk no more than 2% of their money on any given trade.
For example, an investor with a $25,000 account, for instance, cannot risk more than $500 every trade (2% x $25,000) if they choose to set their maximum account risk at 2%. The investor has only lost 20% of their investment capital, even if they lose ten straight deals.
The next step is to decide where to put their stop-loss order for that particular investment. The trade risk for trading stocks is the difference, expressed in US dollars, between the target entry price and the stop-loss price. The transaction risk is $20 per share, for instance, if an investor plans to buy Apple Inc. at $160 and puts a stop-loss order at $140.
The investor now understands that they are risking $20 per share and potentially $500 each trade. The trader just has to divide the $500 account risk by the $20 trade risk to determine the appropriate position size based on this information. Thus, 25 is the appropriate position size for this trade ($500 divided by $20).
Investors need to understand that even with proper position sizing, a stock gapping below their stop-loss order might result in losses greater than the set account risk limit.
When volatility is expected, traders who wish to limit gap size risk should halve their position size as a precautionary measure.
