Number of Shareholders and Stock Prices: Evidence from Japan 总被引:4,自引:0,他引:4
Merton (1987) proposes that an increase in a firm's investor base increases the firm's value. In Japan, companies can reduce their stock's minimum trading unit—the number of shares in a "round lot"—which facilitates trading in the stock by small investors. We find that a reduction in the minimum trading unit greatly increases a firm's base of individual investors and its stock liquidity, and is associated with a significant increase in the stock price. Further, the stock price appreciation is positively related to an increase in the number of shareholders. 相似文献

Prospect Theory and Mean-Variance Analysis 总被引:5,自引:0,他引:5
The experimental results of prospect theory (PT) reveal suggestthat investors make decisions based on change of wealth ratherthan total wealth, that preferences are S-shaped with a risk-seekingsegment, and that probabilities are subjectively distorted.This article shows that while PT's findings are in sharp contradictionto the foundations of mean-variance (MV) analysis, counterintuitively,when diversification between assets is allowed, the MV and PT-efficientsets almost coincide. Thus one can employ the MV optimizationalgorithm to construct PT-efficient portfolios. 相似文献

Depreciation is an economic outlay, though not a cash outflow. It is recognized as an outlay for tax purposes. This paper deals only with the tax effect of the depreciation method, emphasizing the impact of inflation on both the optimal depreciation method and optimal combination of production factors chosen by firms. In the U.S. and other countries accelerated forms of depreciation were adopted. These methods are analyzed and an optimal one is proposed. 相似文献

Evidence from equity markets worldwide indicates that the Day‐of‐the‐Week anomaly appears to fade from the first moment of the distribution of daily returns. We report highly significant pair‐wise weekend effects in high moments when comparing the first and last trading days of the week. The second moment alone appears to distinguish the return distribution of the first trading day from all others. A probable explanation of the phenomena appears to be information dissemination: corporate announcements released after closing of the last trading day of the week spill‐over to the opening of the first trading day, increasing its variability and carrying the closing sign. 相似文献

An asset is liquid if it can be traded at the prevailing market price quickly and at low cost. We show that in addition to
risk, liquidity affects asset prices and returns. Theories of asset pricing suggest that the expected return of an asset is
increasing in its risk, because risk-averse investors require compensation for bearing more risk. Because investors are also
averse to the costs of illiquidity and want to be compensated for bearing them, asset returns are increasing in illiquidity. Thus, asset prices should depend on two asset characteristics: risk and liquidity. This paper surveys research on the effects
of liquidity on asset prices and returns, showing that liquidity is an important factor in capital asset pricing. 相似文献

Does Risk Seeking Drive Stock Prices? A Stochastic Dominance Analysis of Aggregate Investor Preferences and Beliefs 总被引:2,自引:0,他引:2
We use various stochastic dominance criteria that account for(local) risk seeking to analyze market portfolio efficiencyrelative to benchmark portfolios formed on market capitalization,book-to-market equity ratio and price momentum. Our resultssuggest that reverse S-shaped utility functions with risk aversionfor losses and risk seeking for gains can explain stock returns.The results are also consistent with a reverse S-shaped patternof subjective probability transformation. The low average yieldon big caps, growth stocks, and past losers may reflect investorstwin desire for downside protection in bear markets and upsidepotential in bull markets. 相似文献

It is shown that the arbitrage pricing theory holds in eachinfinitesimal period of a continuous trading model under theassumption that dividend payoffs are functionals of factor andidiosyncratic uncertainty. This generalizes the one- periodmodel's result that the arbitrage pricing theory holds underthe assumption that price changes in a given period satisfya factor structure. Since instantaneous returns in a multiperiodmodel are endogenously determined, the theory is derived underassumptions that may be viewed as restricting more primitivecharacteristics of the economy than the assumptions made forthe one-period model. 相似文献
