In perfectly frictionless and rational markets, spot markets and futures markets should simultaneously reflect new information. However, due to market imperfections, one of these markets may reflect information faster than the other and therefore may lead to the other. This study examines the...

For the first time in the Turkish stock market, the width of the zero arbitrage band for BIST 30 stock index arbitrage is measured and decomposed into distinct contributions arising from commissions, fees, bid/offer spreads and stock loan costs. This study also extends the literature of stock...

This article examines the determinants of trading decisions, and the performance of trader types, in the context of the E-Mini S&P 500 futures and S&P 500 futures markets. Although the markets are very similar, essentially trading the same underlying asset but with different contract sizes, some...

This article develops a Hedging Algebraic Model (HAM) for equity index portfolios with stock index futures as an alternative to econometric models (OLS, ECM, and GARCH) and assesses the efficacy of the model when applied to the IBEX 35 for the period 2007-2015. The model is initially formulated...

This paper applies GARCH models to ascertain the impact of index futures trading on the volatility of the spot market. Specifically, the research aims to determine whether the introduction of index futures trading increases or decreases the level of volatility within the underlying spot market....

When stock prices deviate from their fundamental values due to excess demand, investors anticipate reversals and trade in the options market to exploit the temporary misvaluation. This leads to options’ predictability of stock returns beyond the well-known informed trading channel. Using S&P...

We document that leverage-adjusted returns on S&P 500 index call and put portfolios are decreasing in their strike-to-price ratio over 1986-2010, contrary to the prediction of the Black-Scholes-Merton model. We test a large number of plausible unconditional factor models and find that only...
