What is Volatility in the Stock Market?

Exploring the stock market can be challenging, especially during volatile times when prices swing unpredictably. Understanding market volatility, its causes, and how to manage it is crucial for making informed investment decisions. In this blog, we’ll explore what volatility is, how it’s calculated, and its impact on the stock market, particularly in the Indian market. We’ll also discuss strategies to manage volatility and the benefits of using Portfolio Management Services (PMS) to safeguard your investments. 

What is Volatility?

Volatility refers to the degree of variation in the price of a financial instrument over time. It is a statistical measure of the dispersion of returns for a given security or market index and is often used to quantify the risk associated with a particular investment. Higher volatility indicates a higher degree of risk, as prices can change dramatically over a short period in either direction.

What is Volatility in the Stock Market?

Volatility in the stock market represents the rate at which the price of stocks increases or decreases for a given set of returns. A stock with high volatility is likely to experience sharp and unpredictable price changes, while a stock with low volatility typically experiences more stable and predictable price movements.

Take the Indian stock market during the COVID-19 pandemic as an example. The BSE Sensex, a primary stock market index in India, saw big ups and downs. From January to March 2020, the Sensex dropped by over 30%. But then, it bounced back quickly in the following months. This shows how the market was very volatile during that time.

How is Volatility Calculated?

Volatility is usually calculated using statistical methods such as standard deviation or variance. Here are the common methods:

Historical Volatility measures a stock’s past price fluctuations over a specific period. It is typically calculated as the standard deviation of daily returns.

Implied Volatility is derived from the market price of a market-traded derivative (usually an option) and represents the market’s expectation of future volatility.

To illustrate, if a stock’s returns over the past month have a high standard deviation, it is said to have high historical volatility. Conversely, if the market expects significant future price swings (implied by high option prices), the stock has high implied volatility.

What Causes Volatility?

Several factors can cause volatility in the stock market, including:

Economic Data: Reports on employment, inflation, and GDP can impact investor sentiment and cause price swings.

Political Events: Elections, government policies, and geopolitical tensions can lead to market uncertainty.

Corporate Performance: Earnings reports, mergers, and acquisitions can significantly affect stock prices.

Global Events: Natural disasters, pandemics, and other global crises can create market instability.

For example, the announcement of a government policy change, such as the demonetisation in India in 2016, led to immediate and significant volatility in the Indian stock market.

Types of Volatility

Volatility can be categorised into different types:

Historical Volatility

This is the actual volatility that has occurred in the past. It’s calculated using past prices of an asset. If you look at a stock’s price changes over the last year, you can determine its volatility. Historical volatility gives you an idea of how much the asset’s price has fluctuated previously.

Implied Volatility

Implied volatility is a forecast of how much volatility is expected. It’s not based on past prices but instead derived from the prices of options in the market. When traders think there will be significant price swings, implied volatility increases. When they expect stable prices, they go down. Implied volatility is crucial for options traders as it impacts the pricing of options contracts.

Market Volatility

Market volatility refers to the overall level of volatility in the entire market. It’s often measured by indices like the VIX (Volatility Index). When the VIX is high, the market is expected to be more volatile. Economic events, political news, or major financial decisions can influence this type of volatility.

Asset-Specific Volatility

This type of volatility examines the price fluctuations of a specific asset, such as a stock, bond, or commodity. For example, tech stocks might have higher asset-specific volatility than utility stocks because the tech industry is fast-changing and more unpredictable.

Currency Volatility

Currency volatility refers to changes in exchange rates between different currencies. This is crucial for businesses and investors involved in international trade. Interest rates, economic policies, and geopolitical events can influence currency volatility.

Interest Rate Volatility

This type of volatility focuses on changes in interest rates. It affects bonds and other fixed-income securities. When interest rates are expected to change frequently, the volatility of these financial products increases. Interest rate volatility is often linked to central bank monetary policy decisions.

How to Manage Volatility?

Managing volatility involves strategies to mitigate risk and protect investments. Here are some methods:

Diversification: Spreading investments across various asset classes to reduce risk.

Hedging: Using financial instruments like options to offset potential losses.

Asset Allocation: Adjusting the proportion of different assets in a portfolio according to market conditions.

Why are Portfolio Management Services Important?
