How does investor sentiment influence stock prices?

Investor sentiment—the overall mood and attitude of market participants—plays a crucial role in stock price movements, sometimes even more than fundamentals.

What is investor sentiment?

It's the collective feeling of investors about the market, a sector, or a specific stock. It can be bullish (positive) or bearish (negative).

How sentiment moves prices:

Sources of sentiment:

Sentiment vs. fundamentals:

Sometimes stocks move based on sentiment even when fundamentals haven't changed. A stock can rise on positive news coverage or fall on negative social media buzz, regardless of actual business performance.

The sentiment cycle:

1. News or event occurs

2. Initial reaction based on facts

3. Sentiment amplifies the move (often beyond fundamentals)

4. Eventually, price corrects toward fundamental value

Why it matters:

Understanding sentiment helps investors recognize when prices may be driven by emotion rather than fundamentals, creating opportunities or risks.

Tracking catalyst events helps investors understand when sentiment shifts might occur.
