What is a characteristic of noise traders in the market?

• A. They always make consistent gains.
• B. They contribute to market stability.
• C. They exhibit performance dispersion due to idiosyncratic trading.
• D. They follow established trading algorithms.

Answer: (C)

Noise traders are characterized by their erratic and often irrational trading behaviors, which lead to performance dispersion. This means that their trading results can vary significantly, not following a consistent pattern of success as seen with informed or rational traders. Their decisions are typically based on psychological factors, market sentiment, or incomplete information rather than fundamental analysis. As a result, some noise traders may experience significant gains while others may incur losses, reflecting the unpredictable nature of their trading strategies. This is what leads to the performance dispersion that differentiates them from more disciplined market participants.

The other choices do not accurately capture the essence of noise traders. For instance, noise traders do not consistently generate gains; in fact, their trading can lead to losses. Additionally, instead of contributing to market stability, their behavior can increase volatility and create mispricings in the market. Lastly, noise traders do not adhere to established trading algorithms, as their trading decisions are often driven by subjective judgments rather than systematic approaches.
