We show that the presence of high frequency trading (HFT) has significantly mitigated the frequency and severity of end-of-day price dislocation, counter to recent concerns expressed in the media. The effect of HFT is more pronounced on days when end of day price dislocation is more likely to be...

It is a stylized fact that trade indicator models (e.g. Madhavan, Richardson, and Roomans (1997) and Huang and Stoll (1997)) underestimate the bid-ask spread. We argue that this negative bias is due to an endogeneity problem which is caused by a negative correlation between the arrival of public...

Since the early 2000s liquidity in option markets has become less resilient, and our evidence suggests that it is so because of an increased vulnerability to liquidity shocks in the underlying. To demonstrate the causal impact, we consider an incident in which a large broker dealer erroneously...

The first Exchange Traded Note (ETN) was introduced in 2006. Since then, at least 64 other ETNs have been issued, with more announced. This financial security, which is growing in number and popularity, is often confused with Exchange Traded Funds (ETFs) and seems to be largely misunderstood by...

We subdivide trades on the London Stock Exchange according to their reaction times. We classify an aggressive order as 'fast' if it executes against a standing limit order that is less than 50 milliseconds old. We show that fast trades are associated with smaller execution costs than slow...

We survey the growing academic literature using Abel Noser data, including 55 publications thus far. We analyze publication patterns to explore how the availability of a specialized microstructure dataset propagates across different areas within finance and into other disciplines such as...

Why exactly is unclear. The most popular VIX ETPs...

Fractional trading (FT)—the ability to trade less than a full share—allows low-budget retail investors to trade high-priced stocks. This paper quantifies FT's impact on retail ownership and trading of high-priced stocks by exploiting its sequential introduction at four brokerage firms since...

This study tests whether disclosing a trader's identity dampens or stimulates subsequent trading volume based on the trader's reputation for being informed. While a reputation for being informed makes markets less liquid, thus inhibiting subsequent trade ("illiquidity effect"), the information...
