Thinness in Capital Markets: The Case of the Tel Aviv Stock Exchange

Published online by Cambridge University Press:  19 October 2009

Extract

A market is commonly called thin if a large change in price is associated with a small change in supply or demand. The concept of thinness can refer to the markets for stocks, bonds, any category of financial instrument, or even any type of good. Most frequently, thinness has been casually discussed with regard to bond markets and stock markets.

8 It is not clear why the official dealer does not trade for his own account. The only possible explanation is that there are a large number of institutional members of the exchange and they perform the same type of market-making function as the specialist on the New York and American Exchanges (see disucssion in text below).

9 Many of the securities on the TASE are in bearer form so that data on the number of investors could not be collected in any simple way. A sample of securities on the New York and American Stock Exchanges was examined with regard to the relationship between TA, DS, and number of stockholders. The correlation coefficient was .85 between each pair of these three variables.

12 Given that the raw correlation coefficients between DS, V, and P are above .8, there is likely to be a serious multicollinearity problem in the actual regression equations. This would have been true in any case because equation (2) would have had to include DS and P as explanatory variables in order to avoid constraining their coefficients to unity.

13 Douglas, “Risk in Equity Markets,” p. 33. He argues that low-priced securities are traded more heavily by speculators whose activity is likely to be destabilizing. On the other hand, the work by Heins, and Allison, , “Some Factors Affecting Stock Price Variability,” Journal of Business (January 1966) does not validate this hypothesis.CrossRefGoogle Scholar

15 Those variables which could take on a value of zero, e.g., DS, AP, and I were increased by .0001 so that the logarithm could be calculated. This preserved the ordering of the observations, that is, a large quantum jump from zero to the smallest observation (which was .01) with only a slight smoothing of the series.
