Abstract
Investment sentiment has been suggested as one of the
factors significantly affecting market returns. However, studies investigating
the role which corporate transparency plays between investment sentiment and
market returns are still lacking. This study uses the autoregressive model to
measure the relationship among investor sentiment, corporate transparency and
market returns in different sample spans. By analyzing the intraday data in
Taiwan stock market from 2011 to 2013, the findings show that the market
returns are more influenced by investor sentiment when firms are with low
corporate transparency in contrast to those with high corporate transparency,
particularly in the bear market.
