Are Bonds Necessary in an Investment Portfolio: When Stability is More Important than Returns

Home » blog » Are Bonds Necessary in an Investment Portfolio: When Stability is More Important than Returns

In the world of investments, where cryptocurrencies, hype stocks, and risky startups often grab attention, discussions about bonds in an investment portfolio sound almost like common sense. But it is precisely common sense that often saves capital when the market shakes like an elevator without brakes.

The question is not about trend, but about function. And securities have a special role: to balance, smooth out, support. Not to accelerate, but to keep afloat.

Stability in an Unstable World: Why Bonds Are Important for Investors

In the classic case, debt assets are the opposite of stocks. They do not provide explosive growth, but they also do not collapse at the first wave of panic. The income from them is predictable, the redemption is foreseeable, and the risk is lower — that’s why they are loved not only by novice investors but also by large institutions.

Bonds in an investment portfolio reduce overall volatility, allow capital preservation during turbulent periods, and act as a “cushion” during stock market declines. Their function is especially important during crises when even the most reliable stocks can plummet by tens of percent.

The Role of Investment Bonds in the Structure: How They Work for You

Contrary to common belief, government securities are not just an instrument for retirees. They are a mechanism of internal balancing. When stocks fall, bonds often rise, allowing to maintain the average yield of the asset package at a level acceptable to an investor with any profile.

They also play an important role in reinvesting coupon income, significantly increasing capital in the long run. Moreover, they are a way not only to preserve but also to structure savings from a tax perspective: some types of securities are exempt from personal income tax upon redemption.

Advantages of Bonds in an Investment Portfolio

Before including bonds in an investment portfolio, it is important to objectively assess their advantages. Despite being considered a more conservative instrument compared to stocks, this is where their main strength lies.

Firstly, passive investment instruments provide high income predictability. Fixed coupon payments allow to calculate expected profits in advance, which is especially convenient for long-term financial planning.

Secondly, the level of risk when investing in debt assets is significantly lower than when buying stocks. During periods of market volatility, bonds become a kind of “quiet haven” for capital, as confirmed by the behavior of even experienced financiers in unstable economic phases.

Another significant advantage is regular coupon payments. They provide the opportunity to generate a passive income stream, which is convenient for investors who want to receive funds on a regular basis, for example, to cover monthly expenses.

Government bonds, as a rule, have high liquidity, allowing for prompt withdrawal of funds when needed without losing value.

Finally, investment bonds are easy to understand. Even a novice investor can grasp the basic principles of their operation and apply them in their investment strategy without complex technical analysis.

All these features make debt securities a reliable and balanced element of a case — especially during periods of market uncertainty when prudent caution is more important than aggressive growth.

Functions of Bonds in an Investment Portfolio: Not Just About Income

Sometimes it seems that the essence of investing in debt instruments boils down to coupon yield. But the functions are not only about income. Securities perform several tasks at once:

  • act as a source of stable cash flow;
  • reduce overall volatility;
  • provide flexibility in rebalancing;
  • compensate for losses on other assets;
  • ensure capital safety.

Thus, the functions go far beyond the banal “invest and wait for interest.” They are part of a strategy, an instrument for managing risks and financial stability.

Types of Investment Bonds and How to Choose the Right Ones

If you are considering whether to include bonds in your portfolio, it is important to understand that there are many options hidden behind this word: government, municipal, corporate, exchange-traded. Each type has its own yield, liquidity, and issuer reliability.

Government bonds are suitable for those seeking capital protection but are willing to sacrifice yield. Corporate bonds are interesting for those looking for higher returns but are willing to accept additional risks. Municipal bonds are something in between, while exchange-traded bonds (e.g., through ETFs) are a way to quickly diversify without manual selection.

When Do Debt Securities Become Particularly Relevant?

Amid economic downturns, crises, and high inflation, financiers seek a “quiet harbor.” It is in such periods that interest in fixed-income instruments grows. Especially when it comes to government bonds with fixed coupons and stable issuers.

Bonds in an investment portfolio also become a logical step when approaching goals: for example, 2-3 years before a major purchase or retirement. They allow to preserve what has already been earned and not depend on market whims.

How to Make the Right Choice: Tips for Novice Investors

For beginners, it is important not just to include something conservative in capital allocation but to understand which parameters are critical:

  • maturity date — the shorter, the lower the risk, but also the lower the yield;
  • issuer rating — rates are lower for reliable companies and higher for questionable ones, but with risk;
  • coupon — floating, fixed, with amortization or without;
  • taxation — certain types of securities allow reducing the tax burden.

Understanding these factors helps to build a sound strategy even without the involvement of a financial advisor.

Why Is the Set Incomplete Without Debt Assets?

Yes, government securities are not the most “exciting” instrument for a financier. They do not provide high returns, do not stimulate the imagination, and do not make headlines. But if you want your investments to work steadily, they are necessary. Otherwise, the investment structure will resemble a car without brakes: it drives beautifully until it encounters a turn.

Bonds in an investment portfolio are not just “for the elderly,” but for stability. It is a decision that may not be noticeable at the peak of growth but is critically important during a decline. Adding them to capital allocation means not only investing but also thinking ahead!

Creating a portfolio is only half the battle. The real work begins afterwards. Evaluating the portfolio’s effectiveness is the key to control, analysis, and improvement of results, especially when the goals go beyond simple “buy and wait for growth.”

Why Portfolio Evaluation is Necessary

Without measurements, it is impossible to manage — this statement is relevant in investments as well. Financial assets can behave unstably over time: some grow, others decline, and some show zero dynamics. To preserve and increase capital, it is necessary to track not only profitability but also the level of risk, volatility, alignment with goals, and behavior relative to benchmarks.

Simple profit in percentages will not say anything if the losses incurred are not taken into account. Therefore, a professional approach requires the use of precise indicators and mathematical models.

Main Goals and Analysis Parameters

Before starting calculations, it is important to determine what exactly needs to be measured. Evaluation is carried out based on several criteria:

  • return level in relation to risk;
  • income stability and volatility;
  • deviation from the benchmark;
  • balance of asset classes;
  • compliance with personal risk profiling.

All aspects should be analyzed together. Otherwise, a portfolio may be mistakenly considered successful when it has long deviated from the strategy and goals.

Classic Methods of Evaluating Investment Portfolio Quality

The financial industry has accumulated an arsenal of methods that allow for evaluating portfolio effectiveness:

  • Sharpe Ratio — shows how much profit is generated per unit of risk measured by standard deviation;
  • Sortino Ratio — a refined version of Sharpe, considering only negative fluctuations;
  • Treynor Ratio — relies on market risk measured through the beta coefficient;
  • Jensen’s Alpha — demonstrates the excess return over the expected at a given level of market risk;
  • Benchmark — comparison with a benchmark index, such as S&P 500 or an industry indicator.

Formulas allow breaking down the results, removing emotions, and focusing on numbers.

How to Use Sharpe and Its Analogues

The most popular indicator — the Sharpe Ratio — is used to assess the relationship between profit and risk. The higher the value, the more efficiently the portfolio works at the given volatility. However, Sharpe has a weakness: it considers all deviations, including those related to growth.

Here, the Sortino Ratio comes in handy, excluding positive fluctuations and focusing only on potential downturns. This perspective is considered more logical because investors are concerned about the risk of decline, not growth.

For those analyzing results with a connection to market dynamics, Treynor and Jensen ratios are suitable.

Benchmarks: References for Comparison

Understanding how much a case deviates from a basic reference point helps track efficiency not in a vacuum but in the context of the current situation. Typical benchmarks include stock indices such as S&P 500, MSCI World, or industry indicators.

The choice of benchmark depends on the composition of assets. If the case consists mainly of American stocks, comparing with the S&P 500 would be logical. And if it involves global securities, it’s better to take an index reflecting international markets.

Risk Profiling and Its Role in Strategy Selection

Before evaluating portfolio effectiveness and calculating how well it met expectations, it is necessary to align its behavior with personal goals and an acceptable risk level. This is where risk profiling comes into play — determining the investment temperament: conservative, balanced, or aggressive.

The evaluation is based on surveys, preference analysis, and acceptable capital drawdown. A case compiled without considering these factors may be potentially profitable but psychologically unbearable for the owner.

How Diversification Works in Practice

Allocating assets across classes, regions, and industries reduces portfolio sensitivity to unexpected changes. Diversification specifically helps offset declines in some securities with growth in others.

A well-structured set of investments not only looks better but also weathers crises better. For example, a decrease in stocks can be balanced by the growth of bonds or defensive instruments. The effectiveness of distribution can be checked through the return-to-volatility ratio over a long period.

CAPM Model and Markowitz Theory: Fundamental Approaches

Among the classical portfolio study methods, the Capital Asset Pricing Model (CAPM) stands out. It establishes the relationship between expected return and market risk, helping understand if the result aligns with the commitments taken.

Complementing this is the Markowitz Theory, which underpins modern portfolio theory. It states that for a given return, there is a set of assets with minimal risk. Conversely, to achieve higher returns, an investor must accept higher volatility. The task is to find the perfect balance.

Black-Litterman Theory: Modern View on Evaluation

Many consider the Black-Litterman theory a modern reinterpretation of Markowitz. It integrates investor’s subjective forecasts with market objective data, making the model more flexible and applicable to real conditions where participants’ views may vary significantly.

This approach is useful for cases with alternative assets where standard methods may not work.

Which Tools to Choose in 2025?

Evaluating portfolio effectiveness in 2025 requires a comprehensive approach. Simply looking at the final profit percentage is not enough. It is important to consider diversification, benchmark behavior, risk indicators, and stability.

The most accurate picture is provided by combinations: ratios + comparative analysis + behavioral parameters. This system allows for establishing a monitoring style resistant to emotions and sharp movements. After all, the main goal is not just to earn income but to retain it in the long term!

Evaluating the profitability of an investment portfolio allows you to see the results, not just expectations. Numbers determine efficiency, point out mistakes, and indicate where the set of assets is performing poorly. Without accurate calculations, it’s impossible to adapt or forecast a strategy.

What Does Evaluating the Profitability of an Investment Portfolio Show

Evaluating investment results reflects the actual capital growth over a selected period, taking into account profits, losses, and all invested funds. The method captures the real returns from instruments, including stocks, bonds, futures, ETFs, and other assets.

The indicator links three key factors:

  • market value dynamics of assets;
  • holding period;
  • receipts from coupons, dividends, and other payments.

An asset pool yielding +14% annually with average risk and inflation below 5% operates efficiently. However, without analyzing the results for each quarter, evaluating the profitability of an investment portfolio loses its meaning — money doesn’t like blind management.

Formulas Are Important, But Not All-Encompassing

Precise calculation requires specific data. The basic formula looks simple: Profit (%) = [(End-of-period value – Beginning value + Income received) / Beginning value] × 100.

For a diversified portfolio, the correct result comes from weighted profit, considering the proportional weight of each asset. Without it, the numbers distort the picture.

The asset pool includes:

  • 50% of stocks yielding 10% profit;
  • 30% of bonds providing 6% income;
  • 20% of futures resulting in -4%.

Only a weighted calculation reflects reality: 0.5×10 + 0.3×6 + 0.2×(–4) = 6.4%. And only such a calculation of the profitability of an investment portfolio will provide an objective benchmark.

How to Calculate Investment Returns

Linking the calculation to a specific time frame is crucial. The same portfolio can show +18% for a quarter and -3% for half a year if the market corrects. The period affects the perception of efficiency.

For assessing an annual term, internal rate of return (IRR) or modified IRR are often used, especially with irregular investments. These formulas are more complex but reflect the dynamics of fund movement. Without IRR, it’s impossible to correctly calculate the result when funds are irregularly invested and payments vary.

Yield and Profit: Understanding the Difference

Investment profit is an absolute value. Yield is relative. The first depends on the investment amount, the second on the effectiveness of placement. An asset pool with a 7% yield may bring in more money than one with 12% if the investment amount is significantly higher.
Real profit from investments is higher in the first case, despite the lower percentage. Here, the analysis of investment portfolio efficiency should consider the goal: maximizing profit or investment efficiency.

Key Steps in Calculation

Precise calculation starts with a clear action plan. Each step affects the outcome — even the slightest deviation distorts the true picture of investment benefits.

Calculating profit percentage involves the following algorithm:

  1. Choose the calculation period. Start and end dates are fixed. The more accurate the data, the more correct the result.
  2. Evaluate the initial asset value. All assets are recorded at the beginning date based on market price.
  3. Gather income data. Include dividends, coupons, option premiums, and transaction incomes.
  4. Calculate the end-of-period asset value. Market evaluation of all positions, including unrealized profit or loss.
  5. Compute the yield. Apply a formula or automated calculation through services (e.g., Quik, TradingView, Excel with XIRR).
  6. Compare with benchmarks and adjust the strategy. Moscow Exchange indices, S&P 500, Central Bank rate — the basis for efficiency analysis.

Only a comprehensive analysis of financial results will provide a precise understanding of how the set of assets is performing.

Evaluating the Profitability of an Investment Portfolio: Factors Affecting the Final Result

Evaluating the profitability of an investment portfolio depends not only on numbers. The key role is played by investment instruments, their combination, volatility, and holding time. Large-cap stocks provide stability but lag in growth compared to venture assets. Bonds mitigate fluctuations but limit investment benefits. Futures accelerate results but involve risks.

A portfolio consisting of 60% stocks, 30% bonds, and 10% derivatives demonstrates moderate profitability with limited drawdown. Meanwhile, the S&P 500 growth in 2023 was 24.2% — above average. However, high-tech company stocks yielded up to 70% profit, while oil futures resulted in a 12% loss.

Each structure requires adjustments. For high-risk levels and long horizons, it’s more beneficial to hold assets with variable yields. For short-term goals, it’s rational to choose instruments with fixed coupons or high liquidity.

Why Calculate the Profitability of an Investment Portfolio

You can’t manage what you don’t measure. Without understanding the current profitability of a securities portfolio, it’s impossible to make informed decisions: buy more assets, move to cash, hedge positions, or change strategy.

For example, during ruble instability, analyzing the profitability of portfolio investments in currency shows real results, not illusory growth against inflation. In 2022, the Moscow Exchange index decreased by 43%, but when recalculated in dollars, the decline was nearly 60%. This example proves that calculations are necessary in both absolute and relative terms.

Tools for Evaluating the Profitability of an Investment Portfolio

Manual calculation is suitable for simple structures. However, for complex portfolios with numerous positions and different holding periods, specialized platforms are required.

Popular solutions include:

  1. Excel with XIRR function — convenient for accounting for periodic contributions and withdrawals.
  2. Broker’s personal account (Tinkoff, VTB, BCS) — displays asset dynamics online.
  3. Platforms like Black Terminal, Fin-Plan — provide analysis, comparison with indices, and automatic indicator calculation.

Each tool provides information with varying levels of detail. It’s important to cross-check results, eliminate errors, and not rely solely on graphs.

Errors Distorting Results

Mistakenly accounting for losses, double-counting dividends, ignoring fees and taxes are common causes of distortions. Also, evaluating returns without considering inflation is unacceptable: 12% annually with official inflation at 9% yields a real profit of only 3%. Only calculating the profitability of portfolio investments considering these factors reflects reality.

Conclusion

Evaluating the profitability of an investment portfolio allows you to see the efficiency of investments and adjust actions promptly. In a dynamic market with constant changes in securities, those who calculate accurately win, rather than just taking risks.
