Margin regulation and volatility
Brumm, Johannes; Grill, Michael; Kubler, Felix; … - 2014
In this paper we examine the quantitative effects of margin regulation on volatility in asset markets. We consider a … presence of collateral constraints leads to strong excess volatility. Thus, a regulation of margin requirements may have … stabilizing effects. However, in line with the empirical evidence on margin regulation in U.S. stock markets, we show that changes …

Market stability vs. market resilience : regulatory policies experiments in an agent based model with low- and high-frequency trading
Jacob Leal, Sandrine; Napoletano, Mauro - 2016
We investigate the effects of different regulatory policies directed towards high-frequency trading (HFT) through an agent-based model of a limit order book able to generate flash crashes as the result of the interactions between low- and high-frequency (HF) traders. We analyze the impact of the...

Multivariate Volatility Regulated Kelly Strategy : A Superior Choice in Low Correlated Portfolios
Liu, Zhenya - 2017
We propose a Multivariate Volatility Regulated Kelly strategy, which has extra penalization on variance compared to the Kelly criterion. The objective function is constructed and solved. We show the superiority of our method in relative low correlated portfolios, relatively to fractional Kelly...

Forecasting volatility and volume in the Tokyo stock market: Long memory, fractality and regime switching
Lux, Thomas; Kaizoji, Taisei - 2006
We investigate the predictability of both volatility and volume for a large sample of Japanese stocks. The particular emphasis of this paper is on assessing the performance of long memory time series models in comparison to their short-memory counterparts. Since long memory models should have a...

The Markov-switching multi-fractal model of asset returns: GMM estimation and linear forecasting of volatility
Lux, Thomas - 2004
Multi-fractal processes have recently been proposed as a new formalism for modelling the time series of returns in finance. The major attraction of these processes is their ability to generate various degrees of long memory in different powers of returns - a feature that has been found in...

Price pressures
Hendershott, Terrence; Menkveld, Albert J. - 2010
We study price pressures in stock prices-price deviations from fundamental value due to a risk-averse intermediary supplying liquidity to asynchronously arriving investors. Empirically, twelve years of daily New York Stock Exchange intermediary data reveal economically large price pressures. A...

Does volatility matter? Expectations of price return and variability in an asset pricing experiment
Bottazzi, Giulio; Devetag, Giovanna; Pancotto, Francesca - 2009
We present results of an experiment on expectation formation in an asset market. Participants to our experiment must provide forecasts of the stock future return to computerized utility-maximizing investors, and are rewarded according to how well their forecasts perform in the market. In the...
