Introduction to the capital growth model

In financial markets, capital growth is used to calculate the increase in the value of invested capital. The growth is measured by calculating the difference between the initial and future value of an investment or trade.

The objective of a trader is to grow their capital through high level analysis, strategic trade placement, and risk management skills. Using a capital growth model helps traders to estimate how much their initial investment could be worth in the future, and reflect on how well their current positions are performing. The components of calculating a capital growth model include the initial capital, rate of return, and the duration of the investment.

When using a capital growth model, it’s important to remember that traders have to measure the risk exposure of their attempt to achieve a targeted profit. All traders should use risk management tools and plan strategies to increase their chances of success.

In this article, we explore essential skills for achieving growth and protecting invested capital while navigating global financial markets.

Essential skills for a successful trading journey

It’s crucial to mention the importance of learning the instruments of interest and building a solid knowledge on a trader’s target market to build a solid foundation for a successful trading journey.

Mastering market analysis is an essential start point for traders who wish to grow their trading capital. Traders can choose between different approaches to market analysis; including technical, fundamental and sentiment analysis. Technical analysis entails interpreting price changes on the charts to come up with possible predictions for future price movements. Understanding the impact of fundamental aspects such as financial data, and political or geographical dynamics associated with assets, will likely improve the accuracy of investment decisions. Sentiment analysis helps traders to understand the overall mood of markets and how that might affect current and future trends.

After gaining knowledge of market analysis, learning a trading strategy (or several of them) will provide a predetermined and strategic approach to decision-making.

New traders are always advised to start cautiously and build a confident understanding of the market over time. Even for more experienced traders, it’s recommendable to start with smaller trades and increase their position sizes gradually as market cycles unwind. This allows the trader to allocate more capital to segments that show better performance. Diversifying your portfolio across asset classes also allows you to increase or decrease the exposure across multiple segments.

Beginners should seek advice from more advanced traders or professional advisors. Mentorship from experienced market participants, combined with independent research, is a popular way to decode hard concepts and pick up good practices faster.

How to calculate capital growth

There are several approaches to setting growth targets and measuring the growth of your investment. In this section, we’ll explain how to calculate growth forecasts using the approaches of simple percentage and compounded growth.

Simple percentage growth approach

The simplest way of setting a growth objective is to target a specific amount of return based on the invested capital.

For example, a trader’s objective could be that $10,000 of invested capital generates a return of $100 every day. Traders can choose their ideal period for the expected return to be delivered. This could be a day, a week or even a year.

The percentage of $100 of $10,000 is calculated as follows:

100/10,000 multiplied by 100% gives a growth percentage of 1%.

The advantage of this approach is that the trader doesn’t need to adapt the parameters of the positions they open. The position size, risk-reward ratio and asset type can be held constant. As the growth target is small, it’s often achievable by following the same position sizing across all trades.

The main disadvantage of the simple percentage approach is that growth can remain relatively small over time, even if the market would have held potential for higher growth.

Compounded growth approach

Compound growth refers to targeting a certain return on available capital, which is a combination of initial capital and reinvested returns.

For example, a targeted increase of 1% on $10,000 with $100 of reinvested capital over a set period results in the following scenario:

Trade period 1: 1% return on the initial investment of $10,000 = $100, which is reinvested for the next period.

Trade period 2: 1% return on the $10,100 (initial capital + reinvested return) = $101, which is reinvested for the next period.

Trade period 3: 1% return on $10,201 (total balance after trade period 2) = $102, also reinvested for the next period.

The return keeps growing across future trading periods, as the returns are always reinvested back and added to the initial trading capital invested.

However, it’s important to note that the exposure increases as return target increases, necessitating bigger positions or holding trades open for longer periods. Increased exposure comes with higher risks, and traders should always adapt their risk management accordingly.

Market conditions and flexible risk-reward approach

Markets are dynamic and present a wide range of opportunities in different conditions and setups. For example, risky conditions typically require cautious position sizing and lower risk exposure with modest profit targets. Less risky trade setups can allow for bigger positions, with consequently bigger reward targets.

Traders can choose to follow a more flexible approach where return targets are dictated by the market conditions. The advantage of this growth approach is that traders can get higher returns during favourable market conditions and reduce exposure when the risks are high.

However, it’s a less consistent approach which can result to miscalculated risks or uneven growth. It’s good to acknowledge that the right growth model for each trader will depend on their personal preferences and goals. The chosen growth method is most effective when used with a trading style that matches these same preferences.

Sustainable capital growth and risk management

In addition to having market analysis skills and an effective trading strategy, risk management is critical for traders aiming to sustainably grow their capital, as there are no guaranteed returns in financial markets.

Traders need to be prepared to take risk with the expectation to make returns and learn to master how to manage exposure in the markets. Reducing capital erosion through large losses conserves capital for future speculative opportunities.

Risk management requires consistency in following a trading strategy to make high-quality trading decisions. Other aspects of risk management include taking calculated risk in trades, using stop loss orders, diversifying trading portfolio across several asset classes, using leverage carefully and adapting to changing market dynamics.
