With these two indices, the model takes into account the influences from both inside and outside the particular stock market. We find that in large crashes our model gives the crash warning signals shortly after the SET index reaches its peaks and long before the index …

Equity Term Structure Of Property Funds And Reits In Thailand, Chenchai Chotchuangnava Jan 2019

Equity Term Structure Of Property Funds And Reits In Thailand, Chenchai Chotchuangnava

Chulalongkorn University Theses and Dissertations (Chula ETD)

The equity term structure of property funds and REITs in Thailand is upward-sloping. This result contradicts with various studies suggesting that the term structure of risk premia is decreasing. A tenet of those studies is that, by holding long-term equity, investors are willing to forego a part of the compensation to avoid immediate risks which seems to be reverse for property funds and REITs in Thailand. There is evidence that the correlation between size and return is positive. Unlike U.S. REIT, the momentum factor has no application to explain the difference in excess returns.

Is There Risk Reduction In Conglomerate Acquisition?, Paskamon Luntavanich

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study examines risk effect in conglomerate acquisitions through portfolio diversification framework. We find that based on asset diversification potential, acquirers’ risks are expected to decline when they engage in diversifying acquisitions. Interestingly, our result suggests that focus acquisitions are also associated with firms’ risk decrease. With this finding, it indicates that asset diversification potential is also pronounced even when the two assets, i.e., firms from similar industry are combined together. In addition, our results suggest that risks are expected to decline more when diversified firms make further diversifying acquisitions than focus acquisitions but this evidence could not be observed …
