5.1 What Is Fundamental Analysis in Indices Trading?

Fundamental analysis focuses on identifying the underlying forces that influence an asset’s value. Rather than relying on price charts alone, it examines economic data, policy decisions, and global developments that can move markets.

When analysing individual stocks, fundamental analysis looks at company-specific factors such as financial performance, earnings, management quality, and competitive position. However, indices represent a basket of multiple stocks—sometimes hundreds—making company-level analysis less effective.

In indices trading, fundamental analysis concentrates on shared external drivers that affect the entire group of stocks within an index. These include:

• Macroeconomic indicators

• Central bank policies

• Political developments

• Sector-wide performance

• Global events and investor sentiment

For traders at Ohio Markets, fundamental analysis begins with staying informed. Monitoring major economic releases and global news can provide valuable insight into potential index movements.

One essential tool for this is an economic calendar, which tracks scheduled events such as interest rate decisions, GDP releases, inflation data, elections, and geopolitical developments—all of which can impact index performance.

5.2 Key Economic Indicators That Affect Indices

Gross Domestic Product (GDP)

GDP measures the overall economic output of a country. Since stock markets tend to reflect economic strength, positive GDP growth often supports higher index levels. Strong GDP data can boost investor confidence and encourage buying activity across equity markets.

Central Bank Interest Rates

Interest rate decisions play a major role in index movements.

• Lower interest rates reduce borrowing costs, increase liquidity, and often encourage investment in equities.

• Higher interest rates raise the cost of capital, which can reduce investment and lead to market pullbacks.

Indices often react sharply to central bank announcements, especially when decisions differ from market expectations.

Inflation Rates

Rising inflation increases living costs, reducing consumer spending power. This can hurt corporate profits, particularly in discretionary sectors. At the same time, higher input costs can squeeze company margins, negatively affecting share prices and, in turn, indices.

Unemployment Rates

Employment levels directly influence consumer spending, which is a key driver of economic growth. Rising unemployment can slow economic activity and weaken market sentiment, while strong employment data often supports equity markets.

5.3 Sector Performance and Its Impact on Indices

Indices are composed of stocks from multiple sectors, and sector performance plays a crucial role in determining overall index direction.

If heavily weighted sectors perform well, they can push an index higher—even if other sectors underperform. The extent of this impact depends on the index weighting method.

Market-Capitalisation Weighted Indices

In these indices, larger companies have greater influence. If dominant companies belong to the same sector, sector-wide trends can significantly impact the index.

For example, technology stocks carry substantial weight in indices like the Nasdaq 100. As a result, movements in the tech sector can heavily influence index performance.

Price-Weighted Indices

Price-weighted indices give more importance to higher-priced stocks. Sector impact depends on whether the most expensive shares belong to the same industry. A few strong performers can sometimes offset weakness elsewhere.

Equal-Weighted Indices

In equal-weighted indices, each stock contributes equally. Here, index movement depends on the overall balance of advancing versus declining stocks across sectors, making them less sensitive to individual heavyweight stocks.

5.4 Global Events and Market Sentiment

Global events can create rapid and sometimes unpredictable movements in indices. These include:

• Wars and geopolitical tensions

• Elections and policy changes

• Pandemics and health crises

• Supply chain disruptions

• Financial crises and recessions

Beyond fundamentals, market sentiment plays a powerful role. Fear, optimism, and speculation can drive prices independently of economic data. Panic selling or irrational exuberance can cause sharp index swings—even when underlying fundamentals remain unchanged.

This highlights the importance of verifying information sources and avoiding emotional decision-making.

5.5 Case Study: The S&P 500 in 2023

The S&P 500’s performance in 2023 offers a practical example of how fundamental factors influence indices.

At the start of the year, markets faced uncertainty due to persistent inflation, aggressive interest rate hikes, and geopolitical tensions. These concerns led to cautious trading and early volatility.

Despite multiple rate hikes during the year, the index gradually trended higher from mid-2023 onward. Strong labour markets, resilient consumer spending, and optimism around easing monetary policy helped restore investor confidence.

Additionally, major advances in artificial intelligence boosted technology stocks, contributing significantly to index gains. By year-end, the S&P 500 delivered a strong annual performance, demonstrating how markets can recover when economic resilience and positive sentiment align.

• Global events and market sentiment can significantly influence index volatility.

• Staying informed and verifying information is essential for effective decision-making.
