Market Volatility and its Impact on the US Stock Index Movement

The stock market doesn’t stay still. It goes up and down spontaneously, showing dramatic price changes, which is seen as market volatility. A survey conducted by money.com found that in 2022, the stock market experienced increased volatility, resulting in impulsive stock trading, particularly among young investors.

Market volatility can arise from different factors, such as increases in interest rates, economic conditions, wars, political instability, and the monetary policy set by the Federal Reserve. These factors also impact the stock market index movement, creating uncertainty and fear among investors, leading to fluctuations in stock prices. In this article, we will explore the impact of stock market volatility on the stock market index in the US.

The Dance of Market Volatility and Stock Index Movement

Volatility in the stock market is a common part of investment and should be expected in any portfolio, says Nicole Gopoian Wirick, founder of Prosperity Wealth Strategies. Prevalently, volatility is a key factor that affects the stock market index movement in the US—the more dramatic the fluctuations, the higher the level of volatility and potential risk. Recently, volatile markets have become more common. For example, SIRI recorded the highest volatility of 50% in July 2023, according to Trefis.com. Also, Benzinga.com revealed that Cosmos Health and Praxis Precision Medicines companies were listed as one of the most volatile stocks in August 2023. 

Sadly, the ups and downs of the markets and individual securities have sparked different reactions among investors. Investors in some of these top companies sometimes become bearish and adjust their trading strategies, leading to larger price swings in the stock market, and this, in turn, affects the performance of the S&P 500 index and the ES futures market. The ES futures market or the E-mini S&P 500 futures market allows investors to speculate on the future direction of the S&P 500 index. Thus, the S&P 500 index represents the performance of 500 top US companies with common stock listed on NASDAQ or the New York Stock Exchange.

The Ripple Effects on Stock Index Movement

The ripple effects of volatility on stock index movement mean that an increase or decrease in the central market volatility will lead to a decrease or an increase as well amongst other markets. A recent analysis by the IMF shows that when the financial markets are volatile, there is a tendency for spillovers between the cryptocurrency and stock markets to increase. This was evident during events like the market turbulence in March 2020 and significant fluctuations in Bitcoin prices, as witnessed in early 2021.

For example, cryptocurrency prices plunged when SVB (Silicon Valley Bank) crashed on 10 March 2023, and crypto lender Signature Bank crashed shortly after. SVB shares swiftly declined, falling from $267.8 billion as of 4 p.m. on 8 March to $106 billion 24 hours later. This implies that changes in the crypto market can have a ripple effect on the stock market. Thus, a surge in volatility will lead to panic-selling, triggering a domino effect that impacts stock index movement. Conversely, periods of low volatility can induce complacency and a false sense of security, resulting in a high level of risk.

Navigating Volatility: Strategies and Insights

Navigating volatility in the stock market is a very challenging moment for investors. However, strategies like portfolio diversification will help you reduce investment risk. Diversification of a portfolio involves spreading investments in different assets or securities like stocks, bonds, and other cash equivalents to help cushion losses that might arise from the underperformance of a single investment.

Also, make tactical shifts among asset classes by adjusting the investment made across different assets based on the market performance of each asset to reduce risk effectively. In that sense, you must pay more attention to assets that are performing well. Warren Buffett said, “If you are not ready to own a stock for 10 years, don’t even consider owning it for 10 minutes.” Additionally, staying informed about economic indicators, global events, and shifts in market sentiment can empower traders to make well-informed decisions.
