Introduction to Stock Market Volatility

No one does stock investing without understanding what volatility means. Stock Market volatility shows just how unpredictable the stock market really is. The higher and more frequently the stock prices move, the more volatile it becomes. Investors must take their time to properly watch these movements to mitigate risks and make informed and wise investment decisions.

Let’s look into what stock market volatility really means, its causes,types and how to understand it and reduce investment risks

Definition of stock market volatility

Stock market volatility refers to the frequent and irregular movement of prices in a stock or market index over a period of time. It is often measured by the standard deviation of returns. In other words, it shows how far prices move away from their average over time.

In 2023 and 2024, we have seen periods where markets swung wildly due to economic surprises and global events, making volatility an important topic for every investor to know about. Examples are Netflix, Amazon, Tesla amongst others. In 2025, the S&P 500 index had a 10% fluctuation showing just how uncertain the market can be while helping investors make the best decisions.

Importance of understanding volatility for investors

As an investor, you need to understand everything that involves the stock market, including its movements. Why should investors care about volatility?

First, volatility helps to understand investment risks. A stock’s movement can either offer high returns and lower risks or low return and even lower risks. An investor that has a higher risk tolerance can decide to go for the one with higher returns.

Next, volatility helps to make wise investment decisions on which investment plan fits into your goals and investment portfolio. For example, a mix of both high and low volatility stocks would create a balance on the investment portfolio.

Finally, volatility affects market and investment sentiments. When uncertainty rises, investors often react emotionally, causing sharp swings. Understanding this helps investors avoid common mistakes like panic selling or chasing quick gains during turbulent times.

Common Misconceptions About Market Fluctuations

There are several myths and misconceptions when it comes to market fluctuations.

One common misconception is that the market should be stable, and ups and downs are always signs of failure. In reality, fluctuations are normal and necessary for markets to function. In fact, times of high volatility can present buying opportunities when prices drop.

Another myth is that it is always best to hold on to stocks no matter what. However, the truth is that while long-term investment has a lot of advantages, it is essential to watch out for high volatility and risks to avoid big losses.

Also, some think low volatility means no risk, but even stable stocks can lose value due to sudden movements. Conversely, increased volatility does not imply that a stock is unfavorable. It may simply require a stronger stomach to withstand short-term swings.

Investors who understand these facts are better equipped to navigate markets that are more unpredictable due to global economic changes and geopolitical events.

Causes of Stock Market Volatility

Economic indicators and data releases

Economic reports like inflation rates, economic growth, employability rate, amongst others can affect investor decisions.

Imagine if the inflation rate of a country moves at the speed of light! This could lead to investors losing their trust in the economy, leading to rapid shares sales, then to prices going down. On another hand, positive economic news, like an increase in companies’ growth or employment rate, builds investor confidence and causes an increase in buying stock prices, making prices go higher.

These reports act like signals that guide investor decisions and can trigger big market swings.

Political Events and Policy Changes

Majorly, politics can affect how the market moves. New government policies, election results or political instability can create uncertainty for businesses and investors.

For example, new tax laws or trade rules can affect the profits and growth of companies. This can make investors nervous and lead to them rushing to sell stocks. Other issues like war, unrest and political tensions can affect prices. An instance is the Arab Spring uprisings in Egypt in 2011, there was a sharp decline in stock prices on the Egyptian Exchange like the EGX 30.

Politics often play a big role in market movements. Changes in government policy, election results, or sudden political tensions can pull down prices quickly.

Corporate earnings reports

Businesses release earnings reports that show their profits and losses every three months. When a well-known company (maybe a blue-chip stock, eg: Apple and Microsoft) releases a report that shows more loss than profit over and over, they begin to lose stock prices. This could also affect other corporations in that sector.

But, when a company earns more than expected, it can improve investor trust and even boost the entire industry. However, if many companies miss earnings targets around the same time, it can trigger a broader market selloff.

Global Market Influences and Crises

Today, markets are interconnected, so a problem in one country or more could lead to a worldwide market instability. Using COVID-19 as an example, the pandemic led to huge price swings all over the world as a result of restricted movements.

Similarly, changes in oil prices or financial troubles in major economies like the United States or China can cut across markets everywhere. Investors often react fast to these global events, which increases volatility.

Market Sentiment and Investor Behavior

Finally, it is important to note that investors are human and will sometimes make decisions based on how they feel. When investors feel good, they are more likely to buy more stocks, leading to an increase in prices. But, if investors face something that makes them nervous, they try to sell quickly leading to prices falling.

There’s also the herd mentality. When people follow the crowd, prices will swing farther than the true worth of the company.

Measuring Stock Market Volatility

Volatility Index (VIX)

The Volatility Index, also referred to as the VIX, is a measure of expected future volatility of the S&P 500 Index (SPX) – the core index for U.S. equities. It shows how much the stock market is expected to move in the near future, especially over the next 30 days. A high VIX value means that big price swings are expected. On the other hand, a low VIX could mean a stable market with reduced price changes. Today, investors use the VIX to get an understanding of market risk as well as investor sentiment.

Standard Deviation and Variance

Standard deviation and variance are statistical tools that are used to measure how much stock prices move around their average price.

Standard deviation tells us how widely distributed prices are from the average prices. A higher value means higher prices and volatility.

Variance is simply the square of standard deviation and is less commonly used directly but important in calculations. For example, if a stock has a standard deviation of 5%, it means its price typically moves 5% above or below the average price. These numbers help investors understand how risky a stock is compared to others.

Historical volatility vs. Implied Volatility

Historical volatility looks at the story that a stock or index has told over time. It examines how a stock price has changed over a particular span of time, like the past 30 or 90 days. This helps to notice patterns and to understand previous dangers.

On the other hand, implied volatility has more to do with predictions. It forecasts how much price movement the market is expecting.

Both metrics are helpful in managing the difficulties that volatility presents and comprehending how it affects investments.

Types of Market Volatility

Short-term Volatility

Short-term volatility is the quick and sudden change in prices over a few days or weeks. These changes can be affected by news, company reports, political changes, etc. Long-term investors would typically ignore these short fluctuations.

Long-term Volatility

As opposed to short-term volatility, long-term volatility happens over months or even years. They are usually a result of big market changes due to economic cycles, trends, or global events. Let’s look at the FTSE 100, for instance. Its decline started with the financial crisis of 2008, but after going through a period of recovery, economic instability affected it too. Then came the COVID-19 in 2020, leading to big market drops and a slower recovery.

Systematic vs. Unsystematic Volatility

There are two categories of volatility:

Systematic Volatility: This affects the entire market or many stocks at once. Its causes include interest rate changes, inflation, or political instability. It’s like a strong wind that shakes everything in the market.

Unsystematic Volatility: This only affects a specific company or industry. For example, a tech company’s stock may become volatile if it releases a new product or faces a lawsuit. This type can be reduced or avoided by diversifying your investments across different sectors.

Both types show the risk in the stock market, but understanding the difference helps investors manage risk better by spreading their money wisely.

Risks Associated with High Volatility

Loss of Investment Value

One of the biggest risks with high volatility is loss of money. Stock prices can drastically drop, leading to a decreased value in your investments. An example is the significant and sudden fall of Jumia in 2019. This drop was caused by issues with its governance, finance and sustainability. This kind of sudden loss can be scary, especially if you need to sell shares when prices are low.

Increased Trading Costs

Volatility can cause markets to rise, leading to investors buying and selling stocks more frequently. The higher the trading and transaction, the greater the fees, charges and taxes. If an investor trades a lot to capitalize on market movements, these charges can eat into profit. Volatile markets can lead to increased trading expenses more than calmer times.

Emotional Decision-Making

Investors frequently experience anxiety or overconfidence when prices fluctuate wildly. This could lead to emotional decisions like panic selling or impulsive purchases. Long-term success is typically harmed by this behavior.  Many investors tend to lose out on profits by selling low and buying high when they respond to market fluctuations too soon.

Impact on Long-Term Portfolio Performance

Though volatility can seem risky, it doesn’t always harm long-term investing. However, if you panic or trade too often during volatile periods, your portfolio returns may suffer. Staying disciplined, diversifying investments, and focusing on long-term goals help reduce volatility’s negative effects. For instance, data shows that patient investors who held stocks through the 2008 financial crisis saw strong rebounds within five years.

Strategies to Manage Risk During Market Volatility

Diversification Across Sectors and Assets

Diversification has always been one of the best risk mitigation strategies. You can do this by spreading your investments across different sectors and/or various asset types. This way, if one sector falls, others might do well, balancing your overall portfolio. For example, during the 2020 COVID crash, some sectors like tech actually grew while others dropped sharply.

Dollar-Cost Averaging

Dollar-cost averaging means choosing to invest a fixed amount regularly, irrespective of what the market is saying. This evens out your expenses over time by enabling you to purchase more shares at low prices and fewer at high ones.It’s an excellent method to relieve the stress of attempting to time the market precisely.

Hedging with Derivatives

Hedging means protecting your investment against losses by using financial tools like options or futures. Although more advanced, these tools can reduce risks, especially for large investors. There have when inflation caused market swings, hedging helped some investors limit their losses.

Maintaining a Cash Reserve

Holding cash during volatile times is a smart idea because you have cash at hand to cover your expenses when market prices drop. Having a cash reserve means you don’t have to sell assets at a loss.

Setting Stop-Loss Orders

A stop-loss order is an instruction to sell a stock automatically if its price falls to a certain level. This prevents bigger losses by exiting a position before the price drops further. For instance, if you buy a stock at 100 naira, setting a stop-loss at 90 naira helps limit your loss to 10%.

Long-Term Investing and Volatility

Staying Focused on Investment Goals

Stock market volatility means prices can move up and down quickly. However, as a long-term investor, you need to put all sentiments aside and focus on your goals. There is a long line of history concerning the movement of stock market. So, keep your eyes on your plans and don’t follow the market noise.

Avoiding Panic Selling

When investors lead with emotions, they can end up panic selling when the market falls. This is usually a bad idea as it could lead to losses. It is, therefore, important to remain calm and avoid emotional or hasty decisions. By resisting the urge to sell when things look bad, you give your investment the best chance to grow.

Taking Advantage of Buying Opportunities

Volatility can actually create chances to buy good shares at lower prices. When other investors panic and sell, prices drop. If you have a long-term mindset, you can use these moments to buy quality stocks cheaply. This helps you build wealth over time as the market recovers and grows. So, rather than fearing volatility, see it as an opportunity to invest more wisely.

The Nigerian Insurers Association (NIA) has inaugurated its 2025 Innovation Lab, a facility designed to accelerate digital solutions and reshape insurance practice in the country.

Speaking at the launch on Monday in Lagos, NIA Chairman, Mr Kunle Ahmed, said the initiative marked a milestone in repositioning the industry for a technology-driven future.

Mr Ahmed recalled that at his inauguration in October 2024, he emphasised the need for insurers to embrace digital innovations and pledged to establish an innovation challenge to foster new solutions.

“Today, we are not just opening a facility, we are igniting a movement, rooted in innovation, driven by collaboration, and destined to transform the way we protect lives, assets, and futures,” he said.

Mr Ahmed explained that the lab would serve as a hub where ideas would be nurtured, technologies tested, and scalable solutions developed for the Nigerian market.

According to him, the youthful demographics of Nigeria, with a median age of 18 years, make it imperative for insurers to adopt digital platforms, artificial intelligence, blockchain, and data analytics.

He said this was needed to improve efficiency, expand access, and deepen trust.

“Innovation is not a luxury. It is a necessity. The future of our industry depends on agility, inclusiveness, and digital empowerment,” he said.

Mr Ahmed urged regulators, technology partners, and member companies to collaborate with the association in making the innovation lab a success.

He described the lab as a symbol of unity of purpose and diversity of thought, adding that it would serve as a platform for continuous learning and adaptation in a rapidly changing world.

“To our innovators, this is your launchpad, your opportunity to shape the future.

“To our member companies, invest in this future. And to every Nigerian, believe in the power of innovation to protect assets and sustain standards of living,” he said.

On his part, Mr Babatunde Fajemirokun, who chairs NIA’s Advisory Committee on Digital Innovation and IT, presented insights from the survey earlier conducted which informed on the challenging areas to wade into.

The survey, which engaged 45 senior leaders including 22 Chief Executive Officers, 10 Chief Technology Officers, and 13 heads of strategy across life, general, and micro-insurance, revealed areas where the industry must channel its focus.

“The data reveal a sector ready to embrace innovation, with 87 per cent of executives expressing willingness to collaborate on shared solutions and 69 per cent confirming readiness to commit resources in 2025.

“Customer experience, acquisition, KYC, and distribution rank as the top priorities for innovation.

“Fraud management, eKYC, and claims exchange emerged as the most promising areas for industry-wide collaboration,” he said.

For the second consecutive month, Nigeria maintained its crude production quota of 1.5 million barrels per day in July 2025.

According to the August 2025 Monthly Oil Market Report (MOMR) released by the Organisation of the Petroleum Exporting Countries (OPEC), Nigeria was able to sustain its crude oil production for two months straight.

As part of efforts to avoid oil glut, which refers to having too much oil supply in the global market, and keep prices stable to help economies grow, OPEC provided every member country with a production cap.

For Nigeria, it has not been able to reach the level in recent times until January 2025, when it recorded the highest output of 1.54 million barrels per day.

However, it dropped below the 1.5 million barrels daily mark in February until May.

Momentum picked up again when the country’s average daily oil production rose to 1.505 million barrels per day in June.

It has now sustained this again with data showing Nigeria produced 1.507 million barrels per day in July.

Prior to this, production averaged 1.453 million barrels per day in May.

Crude production dropped to 1.46  million barrels per day in February, 1.40 million barrels per day in March, 1.48 million barrels per day in April and 1.45 million barrels per day in May.

Nigeria is actively boosting crude oil production by reactivating dormant fields, fast-tracking regulatory approvals, and enhancing operational efficiencies across the upstream value chain.

With the country’s production picking up, the Group Chief Executive Officer (GCEO) of the Nigerian National Petroleum Company (NNPC) Limited, Mr Bashir Bayo Ojulari, noted that this could lead to country to ask for a higher output benchmark from OPEC.

Oil accounts for over 60 per cent of Nigeria’s foreign earnings and a higher output quota will help boost the country’s foreign reserves and reduce the need to borrow to fund the N54 trillion budget for 2025.
