Introduction
Introduction
Do you have a portfolio of investments? If so, it’s important to understand how to measure the risk of your portfolio. In this blog post, we will discuss the essential steps to risk analysis. By understanding portfolio risk measures, you can protect your investments and ensure that your portfolio is as stable as possible. It’s also important to match the risk that your portfolio is exposed to, with the risk you are willing and capable of bearing. This pertains not just to asset allocation, but also to which specific holdings within those asset classes you own. This is also dynamic: it will change over time as different assets grow at different rates, introducing the need for portfolio rebalancing. Additionally, maintaining a keen eye on the financial health of your portfolio is crucial, as it helps navigate through internal business risks such as operational challenges, leadership changes, and weak portfolio governance, ensuring long-term stability.
What is portfolio risk, its asset allocation implications, and why it's important to measure
Investment portfolio risk refers to the vulnerability of your investment portfolio, a collection of financial instruments like stocks, bonds, and funds, to changes in market conditions. Understanding market risk is crucial for constructing an investment portfolio with the objective of achieving a particular level of risk and return, as it represents the risk of losses due to factors that affect the entire market. This includes the covariance of the stocks, which remains as market risk even after diversification eliminates other risks. It is important to measure investment portfolio risk because it allows you to understand your risk tolerance and manage risk through a broad set of investments, helping to identify and address any potential weaknesses or vulnerabilities that could cause your portfolio to lose value or become unstable. There are several different portfolio risk measures that you can use, such as Sharpe ratio, beta, and VaR.
The different types of portfolio risk measures, including market risk
One of the most commonly used portfolio risk measures is the Sharpe ratio, which measures the excess return of your portfolio relative to its volatility. This allows you to see whether your portfolio is generating higher returns than a benchmark portfolio for a given level of risk. Ie are you being adequately compensate for the amount of risk that you are taking?
Another important portfolio risk measure is beta, which measures the sensitivity of your portfolio to changes in the market. This can help you to determine how risky your portfolio is and whether it is well-diversified or not. A beta of more than one means that for each 1% change in the market, your portfolio will move by more than 1% in the same direction, and vice versa.
Adding to these, the Capital Asset Pricing Model (CAPM) serves as another crucial portfolio risk measure. CAPM is utilized to evaluate the risk of an investment in relation to its expected return, taking into account the risk-free rate and the asset’s sensitivity to market movements, known as beta. This model aids investors in pricing assets correctly by understanding the relationship between risk and expected return, thereby ensuring that they are compensated for the risk undertaken.
Yet another portfolio risk measure is VaR, which estimates the maximum possible losses that your portfolio could incur over a given time period. Being able to accurately estimate these potential losses can help you to proactively manage portfolio risk and prevent any significant losses.
If you are interested in measuring portfolio risk, it is important to seek out the professional guidance of a financial advisor or investment manager who can help you choose the right portfolio risk measures for your individual situation. With proper portfolio risk analysis, you can protect your investments and ensure that your portfolio remains stable in the long-term.
To maximize business value delivery, it is crucial to manage risk through comprehensive portfolio risk management, involving senior leadership in identifying, assessing, measuring, and managing risks that could impact strategic objectives.
How to calculate the standard deviation of your portfolio
There are several different portfolio risk measures that you can use depending on your specific situation and portfolio goals. One common portfolio risk measure is the standard deviation, which is a statistical calculation that quantifies how much variation there is in your portfolio returns over time. To calculate the standard deviation of your portfolio, you need to take the average portfolio return over a set time period, then calculate the square root of the portfolio variance.
Another portfolio risk measure that is commonly used is beta, which measures how closely your portfolio tracks the market as a whole. To calculate portfolio beta, you need to compare the returns of your portfolio with those of an appropriate benchmark portfolio.
In addition, you can use portfolio VaR to estimate the potential losses that your portfolio could incur. To calculate portfolio VaR, you need to consider a range of possible market scenarios and then estimate how these scenarios would impact your portfolio's value.
Overall, there are many different portfolio risk measures that you can choose from depending on your specific portfolio needs. Now, calculating these yourself regularly is a lot of work, and something that most people don't have the time or capacity to do. For that reason, we've automated it in app!
How to use historical data to predict future portfolio risk
One effective way to measure portfolio risk is to use historical data to analyse the trends in your portfolio returns over time. This can involve examining both the returns on individual securities and the overall portfolio returns for a given time period. Analyzing historical data is also crucial for understanding how liquidity risk has impacted the portfolio in the past, aiding in better predictions for future risk management.
Once you have analysed this historical data, you can use it to make predictions about future portfolio risk. For example, you might look at historical portfolio beta to identify any patterns or trends in your portfolio’s sensitivity to market changes.
Additionally, you can use various statistical techniques and financial models to estimate the likelihood of different portfolio losses under a range of market scenarios. By combining these predictive tools with historical data on portfolio returns and risk, you can gain a clearer understanding of your portfolio’s overall risk profile.
Overall, using historical data to measure portfolio risk can help you make informed investment decisions and proactively manage portfolio risk over time. Now, of course you should be aware that past performance is not an indication of future performance, and is only useful as a rough guide to what you might expect.
Tips for portfolio risk management by reducing portfolio risk
Understanding and managing portfolio risks is essential for investors, emphasizing the importance of diversification and seeking professional advice to navigate these challenges effectively. There are several different strategies that you can use to reduce portfolio risk. One important step is to diversify your portfolio by including a variety of different investment types, such as stocks, bonds, and cash equivalents. This can help to smooth out portfolio returns over time and lower the overall portfolio risk. Additionally, managing portfolio risk is crucial and requires a comprehensive approach that includes diversification, seeking professional advice, and employing hedging strategies to safeguard investments against various types of risks, including systematic and currency risks.
Another strategy for reducing portfolio risk is to seek out professional portfolio management services. A portfolio manager can help you choose the right portfolio risk measures for your situation, and they can also provide guidance on how to proactively manage portfolio risk in the long-term. Aligning your investment strategy with your risk tolerance is essential for effectively reducing portfolio risk, as it ensures that decisions are made with a clear understanding of both the company’s financial goals and the riskiness of individual investments.
In addition, you may want to consider using various portfolio hedging techniques, such as options or futures contracts, to help limit portfolio losses. By working with a financial advisor, you can explore the different portfolio hedging options available and determine which techniques may be most appropriate for your portfolio.

Why Use Investing Apps in the UK
Investing is now simpler than ever thanks to these applications, which get rid of the need for pricy brokers or complicated procedures. Investing apps like Trading 212, Freetrade, and Revolut make it possible for young and beginner investors to take control of their investments with their user friendly interfaces, built in educational tools and minimal or no costs.
As the need for low cost investing options and financial independence continues to grow, the UK is expected to utilise mobile investing tools even more in 2025. More people in the UK are using apps to manage their money as a result of its adaptability, simplicity of use, and the growing trend towards digital financial solutions and increased awareness of personal financial planning, which makes investing apps an effective tool for beginner investors.
Benefits of Using Investing Apps for Beginners
- Accessibility - By providing a straightforward, mobile friendly platform that is available at anytime and from any location, investing apps have completely changed how individuals invest. You no longer have to spend hours learning complicated systems or setting up sessions with financial experts. Beginners can begin investing directly from their smartphones with a few taps. Anyone, regardless of their schedule or location, can participate in investing without any obstacles thanks to this immediate access.
- Low cost - The affordability of investment apps is one of their most notable benefits. The high commissions and administration costs associated with traditional broking services make it challenging for those starting out to invest small amounts of money. On the other hand, a lot of investment apps provide cheap fees or commission free trading, which makes them perfect for beginners. This enables beginners to invest without fear of losing a significant amount of their profits to fees, allowing them to give more money to the market.
- Adaptability - Traditional investment strategies are not as flexible as investing apps. Beginners can more easily dabble without making a significant upfront payment because many investment platforms enable users to invest in a variety of assets, stocks and shares, exchange traded funds (ETFs), and specialised investment options, allowing beginners in the UK to diversify their investment portfolios right away. Furthermore, everyday investors may manage their investments on their own terms and are not restricted to a 9 to 5 schedule thanks to the option to trade at any time and from any location.
