"The 'magnet' or 'gravitational' effect hypothesis asserts that, when trading halts are rule-based, investors concerned with a likely impediment to trade advance trades in time. This behaviour actually pushes prices further towards the limit. Empirical studies about the magnet effect are scarce,...

We study if VPIN (Easley, López de Prado, and O'Hara, 2012, Review of Financial Studies 25, 1457-1493) is an efficient advance indicator of toxicity-induced liquidity crises and related sharp price movements. We find that high VPIN readings rarely signal abnormal illiquidity, and very...

We introduce a methodology to obtain friction-free estimates of Barclay and Warner's (1993) Weighted Price Contribution (WPC). With this new approach, we verify recent simulation results suggesting that trading frictions may severely bias the WPC approach. We use high frequency data from a...

We show that illiquidity risk matters for asset pricing independently of the specific functional form of the asset pricing model. Employing an out-of-sample non-parametric stochastic discount factor (SDF), that we estimate from portfolio returns of the US equity market, we find that market-wide...

By adverse-selecting liquidity providers, toxic order flow harms liquidity. We empirically examine which components of modern markets' net flow of orders convey information and signal toxicity. We find that the net flow of non-marketable orders is more informative than the trade-initiator-based...

We show that illiquidity risk matters for asset pricing independently of the specific functional form of the liquidity-based asset pricing model. Employing a non-parametric model-free stochastic discount factor (SDF), estimated using different sets of portfolio returns coming from both the stock...
