The effects of stated preferences for firm characteristics, optimism and overconfidence on trading activities

The purpose of this paper is to test the competing explanations of stated preferences for firm characteristics, optimism and overconfidence for trading activities in a single framework.

A survey methodology is followed to collect the data among retail investors in Malaysia using simple random sampling.

The findings show simultaneous identification of stated preferences for firm characteristics, optimism and overconfidence as determinants of trading activities. Preferences for firm’s profitability characteristics, management and product-related attributes and risky characteristics are likely to decrease investors’ trading activities. On the other hand, preferences for firm’s liquidity and trading volume characteristics with relative financial-domain optimism, personal investment optimism and better-than-average aspect of overconfidence are likely to increase investors’ trading activities.

This finding implies that investors should be careful not only in assessing firm’s characteristics but also need to understand the effects of optimism and overconfidence in trading decisions.

The study considers various aspects of optimism and overconfidence, and the stated preferences for firm characteristics, unlike one aspect of these behavioral biases and indirect observation of preferences for firm characteristics. Furthermore, the study considers trading frequency, annual portfolio turnover and trading intention, whereas earlier studies considered only one or two of these trading decisions.
