The disposition effect in the Chinese stock market

We OUBS students do these seminars for each other. Presenting to each other has benefits:
  • it's friendly so less scary than for real
  • your colleagues might give you some good ideas on how to develop your research
  • it's one of the PhD skills you have to have (E3: Constructively defend research outcomes at seminars and viva examination - see joint skills statement)
  • it's good practice
  • it builds up the student community
Today one of our first year student's presented on
The disposition effect in the Chinese stock market.
Each PhD student has a web page, but she hasn't got hers yet, so I'll try to write up something of what I think she said.

Aim: find out how demographic factors influence individual investors disposition effect in China.
Research questions: there were three; the first two are about what the effect is and the third is about the reasons for that effect.
Methodology: Odean's model (1998) on the disposition effect can be measured by PGR- PLR (proportion of gains realised and the proportion of losses realised.

She's going to use quantitative data from a survey of 10,000 to answer the first questions, using factor analysis, and also qualitative data to address the reasons why. She'll use thematic analysis like Braun and Clarke (2006).

We asked her questions about her theoretical framework, about comparison with the western world and why she was using both quantitative and qualitative. We asked her who the research would be useful to. One student suggested a variation to her survey that would simplify and perhaps reduce her qualitative work.
