What is Market Sentiment?

Financial markets are constantly evolving with their volatile dynamics. In this type of environment, investors are highly influenced by the market sentiment factor. 

This term refers to the collective mood or outlook of investors towards a particular financial asset, sector or the market as a whole.

The Importance of Market Sentiment

The importance of market sentiment is revealed when you understand how prices move in financial markets. Prices are determined not only by company earnings reports or economic indicators, but also in direct relation to how investors perceive these factors. 

If we need to explain this issue with an example; imagine a company reports strong earnings but the market has already priced in those results or expects limited growth in the future, its stock price may still decline.

This situation highlights that market sentiment can sometimes be a more effective predictor of market behavior than traditional forms of analysis such as fundamental or technical methods. 

When investors are optimistic about a particular asset, they are highly likely to increase their purchasing activity. This may cause prices to rise. On the other hand, if sentiment turns negative, this usually leads to increased sales followed by a decline in prices.

Types of Market Sentiment

Market sentiment can be positive, negative, or neutral, and it directly impacts how investors choose to buy or sell.

Positive Market Sentiment

Positive market sentiment is when investors have a generally positive view of the market or a particular asset and expect prices to rise. This optimistic outlook usually leads to increased buying, which in turn leads to higher prices and a positive market trend.

Negative Market Sentiment

As the name suggests, negative market sentiment is the negative atmosphere that occurs when investors approach the market with suspicion or are pessimistic, expecting prices to fall. In this case, investors often encounter skepticism and selling pressure, which causes prices to fall.

Neutral Market Sentiment

Neutral market sentiment occurs when investors do not have strong expectations that the market will move in either direction, i.e. positive or negative. 

Investors in this scenario tend to be cautious and wait for clearer signals.

Measuring Market Sentiment

Various methods and tools are used for this purpose, usually involving the analysis of data reflecting the attitudes and expectations of investors and market participants. Let's take a closer look at these methods and tools.

Surveys and Polls: Surveys are one of the most important ways to identify market sentiment, because they measure expectations about future market movements. For example, the American Association of Individual Investors (AAII) Sentiment Survey provides important information on the collective perspective of individual investors.

Volatility Index (VIX): Often referred to as the “fear index,” the VIX measures the expected volatility of S&P 500 options. High levels of the VIX indicate that investors are concerned about potential market volatility.

News Monitoring: Social media platforms and news sources can disseminate market information and opinions extremely quickly. Analyzing posts on platforms such as Twitter and Reddit, as well as news articles, is important in assessing market sentiment.

In addition, tools such as Google Trends can provide insights into investor psychology and sentiment.

Put/Call Ratio: This ratio reflects the balance between protective put options and optimistic call options in the market. A high ratio usually indicates that investors expect the market to be bearish, reflecting a bearish sentiment.

Market Sentiment and Investment Strategies

Taking market sentiment into account and incorporating it into investment strategies is extremely important for investors. In this sense, some of the strategic approaches that emphasize market sentiment are as follows:

Contrarian Investing 

In this strategy, it is important to take positions contrary to prevailing market sentiment. For example, when market sentiment is overly optimistic, investors who are expecting opposite outcomes, may sell their positions expecting a market correction. Conversely, when sentiment is overly pessimistic, they may decide to buy, expecting a market recovery.

Momentum Investing

Momentum traders adjust their approaches based on current market sentiment. Here, as the name suggests, the momentum of the market comes into play. When this momentum or sentiment is positive, the asset is bought and when it is negative, it is sold.

Market Sentiment and Investor Psychology

Market sentiment is able to reflect the collective thoughts and feelings of investors and market participants and plays an important role in predicting price movements.

Investors who pay attention to market sentiment can adjust their methods to align with prevailing trends. That said, sentiment can shift rapidly based on news, economic data, or other events, which makes it worth analyzing as part of a broader strategy. While it offers valuable insight, relying solely on market sentiment without considering other factors can lead to short-sighted decisions.

The Role of Sentiment in the 2008 Crisis

When people were scared, they sold their stocks, and prices went down. When people were optimistic again, they bought stocks, and prices went up. Market sentiment—whether it’s fear or optimism—can have a huge impact on instrument prices, even if the underlying fundamentals of some companies haven’t changed much.

In 2007-2008, as housing prices in the U.S. began to fall and mortgage defaults increased, there was widespread fear and pessimism among investors. Many believed the economy would worsen, leading to a negative market sentiment. 

This fear caused many investors to sell their stocks in panic, believing the market would continue to decline. As more people sold their stocks, stock prices dropped sharply. Major stock indices like the S&P 500 and the Dow Jones Industrial Average fell by more than 50% from their peak.

However, in 2009, sentiment began to shift. Some investors believed that the worst was over and that stocks were undervalued. They started buying stocks again, expecting the market to recover. As more investors bought in, stock prices began to rise. So this change helped fuel the market recovery.
