Index arbitrage and dynamics between REIT index futures and spot prices

This article contributes to the real estate literature by investigating the pricing relationship between REIT index futures and spot. Based on the cost-of-carry model, we first show that there exist three arbitrage regimes in Australia’s REIT spot-futures price dynamics. Further analysis indicates that the two thresholds, which separate the regimes, are largely consistent with the level dictated by transaction costs. We then estimate a threshold vector error correction model (TVECM). The results show that mean reversion of the mispricing error only takes place in the two outer regimes. Furthermore, we find evidence that REIT spot market is more informationally efficient than the futures market. Given its short history, it will take time for REIT index futures market to mature. Finally, we find that we can enhance hedging performance by accommodating the feature of threshold cointegration displayed by the data. As the futures-spot relationship differs across regimes, we can develop a hedging strategy by adjusting the hedge ratio based on arbitrage regimes. It leads to a greater variance reduction for the hedged portfolio than some conventional methods examined in the existing real estate literature.     

No-arbitrage Equilibria with Differential Information: An Existence Proof

On the example of a pure exchange financial economy with two periods incomplete nominal-asset markets and differential information of the adverse selection’s type, Cornet-De Boisdeffre (J Math Econ 38:393-410, 2002) introduced refined concepts of no-arbitrage prices and equilibria, which extended to the asymmetric information setting the classical concepts of the symmetric information literature. We now assess existence issues and extend a standard property of symmetric information models. Namely, we prove that a no-arbitrage equilibrium always exists, as long as financial markets preclude arbitrage, under the same standard conditions, whether agents have symmetric or asymmetric information.     

俄罗斯金融市场套利交易的形成、影响及启示

20世纪90年代以来,俄罗斯在高度开放和自由的经济环境下,开展金融自由化改革,由此导致大量资本通过外债形式进入俄罗斯金融市场进行套利交易,套利资本推动俄罗斯经济、金融业的发展。而当套利资本迅速撤离俄罗斯市场时,俄罗斯金融市场就出现了银行业流动性吃紧、大规模抛售卢布现象,俄罗斯经济受到重创,最为典型的是1998年和2008年俄罗斯爆发的金融危机。文章试图通过研究俄罗斯的套利交易形成的影响因素,深刻理解俄罗斯金融危机。近年来,人民币不断升值,人民币跨境清算范围不断扩大,中国也面临着"热钱"监管压力,研究俄罗斯套利交易,对中国具有重要的借鉴意义。

Arbitrage in stationary markets

We analyse questions of arbitrage in financial markets in which asset prices change in time as stationary stochastic processes. The main focus of the paper is on a model where the price vectors are independent and identically distributed. In the framework of this model, we find conditions that are necessary and sufficient for the absence of arbitrage opportunities. We discuss the relations between the results obtained and the phenomenon of “volatility-induced growth” in stationary markets.

Pricing effects in Fannie Mae agency bonds

As a government-sponsored enterprise, Fannie Mae enjoys certain advantages over other firms. The extent of these advantages, while widely discussed, have not yet been fully quantified. This paper empirically examines the returns to Fannie Mae general obligation bonds under the assumptions of the Arbitrage Pricing Theory. The model provides an explicit method for estimating the risk premium on Fannie Mae bonds. The results indicate that liquidity and tax effects are important in explaining the returns to Fannie Mae bonds. The results also indicate that the market does not incorporate changes in the riskiness of the mortgage market into the returns on Fannie Mae bonds. The results provide support for the contention that Fannie Mae, as a government sponsored enterprise, enjoys a significant advantage over other firms in the capital market.     

Do the diversification choices of individual investors influence stock returns?

This paper shows that the diversification choices of individual investors influence stock returns. A zero-cost portfolio that takes a long (short) position in stocks with the least (most) diversified individual investor clientele generates an annual, risk-adjusted return of 5–9%. This spread reflects the combined effects of sentiment-induced mispricing, narrow risk framing, and asymmetric information, where the sentiment effect is the strongest. Furthermore, the influence on returns is stronger among smaller, low institutionally owned, and hard-to-arbitrage stocks. These results are robust to concerns about relatively short sample size, improper factor model specification, slow information diffusion, and high transactions costs.     

Financially constrained arbitrage in illiquid markets

This article analyzes trading strategies when arbitrageurs impact prices. Trades of financially constrained arbitrageurs are feedback functions of their capital, which depends on the amount traded. A component of arbitrage trading ensures financial flexibility. This hedging component explains why price deviations persist in spite of arbitrage. Financial constraints are responsible for volatile prices and for time variation in the correlations of prices across markets. Distortions arise when regulated firms can influence the dynamics of prices on which capital requirements are based. Under current value at risk (VaR) measures, large traders behave aggressively and have a cost advantage relative to other traders.     

The stock market and investment: another look at the micro-foundations of q theory

This paper introduces a novel distinction between real q andfinancial q. The paper examines three versions of financialq developed by Brainard and Tobin, Minsky and Hayashi, respectively.These theories differ regarding the nature of stock market pricedetermination and their use of marginal productivity theory.It is shown that non-profit maximising behaviour by managersdoes not invalidate q theory. It is also shown that if managersand shareholders have different profit expectations, this leadsto an equilibrium value of q that differs from unity. Lastly,the implicit claims in q theory regarding the efficient roleof stock markets as regulators of capital accumulation are shownto depend on assumptions about stockholder behaviour.
