Asset Prices And Information Traders’ Abilities: Evidence From Experimental Asset Markets, Lucy F. Ackert, Bryan K. Church, Ping Zhang

Faculty and Research Publications

This study reports the results of fifteen experimental asset markets designed to investigate the effects of forecasts on market prices, traders’ abilities to assess asset value, and the link between the two. Across the fifteen markets, the authors investigate alternative forecast-generating processes. In some markets the process produces an unbiased estimate of asset value and in others a biased estimate. The processes generating the biased forecasts, though, are less variable than the process generating the unbiased forecast. The authors find that, in general, periodend asset price reflects private forecasts, regardless of the forecast-generating process. Subsequently, they investigate whether traders’ abilities …

Advanced Portfolio Theory: Why Understanding The Math Matters, Tom Arnold

Finance Faculty Publications

The goal of this paper is to motivate the use of efficient set mathematics for portfolio analysis [as seen in Roll, 1977] in the classroom. Many treatments stop at the two asset portfolio case (avoiding the use of matrix algebra) and an alarming number of treatments rely on illustration and templates to provide a heuristic sense of the material without really teaching how efficient portfolios are generated. This is problematic considering that the benefits of understanding efficient set mathematics go beyond portfolio analysis and into such topics as regression analysis (as demonstrated here).

Investing In Hedge Funds: Risks, Returns And Pitfalls, Francis Koh, Winston T. H. Koh, David Kuo Chuen Lee, Kok Fai Phoon

Research Collection Lee Kong Chian School Of Business

Hedge funds are collective investment vehicles fast becoming popular with high net worth individuals as well as institutional investors. These are funds that are often established with a special legal status that allows their investment managers a free hand to use derivatives, short sell, and exploit leverage to raise returns and cushion risk. Given that that they have substantial latitude to invest, it is instructive to examine the performance of hedge funds compared to other forms of managed funds. This paper provides an overview of hedge funds and discusses their empirical risk and return profiles. It also poses some concerns …

The Search For Stock Market Bubbles: An Examination Of The Nyse Index, Andrew J. Economopoulos, Avinash G. Shetty

Business and Economics Faculty Publications

Many have put forth reasons why the stock market has climbed to new and unprecedented heights. Two reasons are examined: (1) investors are expecting prices to increase and are bidding up price irrationally; (2) investors have moved to a long-term strategy and are requiring a lower risk premium. For the latter reason, the rise in stock prices is due to a change in the fundamentals, and for the former reason the rise represents the classical bubble. The evidence indicates that risk preferences have changed while price momentum does not appear during bubble periods.

Sampling Concepts, Paul Boyd, Ph.D.

MBA Faculty Conference Papers & Journal Articles

The usefulness of any research is dependent upon how well the group studied represents the group about which decisions are to be made or conclusions drawn. That is, it depends upon how well the sample reflects relevant characteristics of the population. When it is possible to study every member of that group there is no problem, for on these occasions we can easily calculate the exact attribute (parameter) of interest for our population.

For example, if we were interested in determining the average number of gallons of gasoline sold to customers at our service station yesterday, we …

Diversification Benefits From Foreign Real Estate Investment, C. Mitchell Conover, H. Swint Friday, G. Stacy Sirmans

Finance Faculty Publications

Previous research has questioned the stability of international equity diversification. This study examines whether foreign real estate exists in a more segmented market and whether foreign real estate provides any diversification benefit beyond that obtainable from foreign stocks. Using data encompassing the stock market crash of 1987, foreign real estate was found to have a lower correlation with U.S. stocks than foreign stocks. This lower correlation is shown to be stable through time as foreign real estate has a lower correlation in nearly the entire time period. Foreign real estate was also found to have a significant weight in efficient …
