The rapid rise of corporate bond portfolio trading since the end of 2017 has attracted attention from practitioners and regulators alike. I show that inventory hedging explains the recent meteoric rise of corporate bond portfolio trading, likely aided by the recent proliferation of credit index...

We examine portfolio trading and its impact on corporate bond liquidity. Our theoretical framework identifies how portfolio trades provide dealers with benefits through a diversification channel and with costs through a balance sheet channel. We then test empirically multiple hypotheses on the...

I investigate the question of how to construct a benchmark replicating portfolio consisting of a subset of the benchmark’s components. I consider two approaches: a sequential stepwise regression and another method based on factor models of security returns´ first and second moments. The first...

We use a CCA model to calculate implied idiosyncratic risks of LBO transactions. A decisive model feature is the consideration of amortization. From the model, the asset value volatility and the equity value volatility can be derived via a numerical procedure. For a sample of 40 LBO transactions...

The authors use a contingent claims analysis model to calculate the idiosyncratic risks in Leveraged Buyout transactions.

This note develops the solutions of the static portfolio optimization problem in explicit matrix form. Three cases are contemplated and connected, with the derivation of relevant corner solutions: the unconstrained problem in the presence of risky assets only, the constrained one, and the...

The main regulations of short selling in Russian stock markets are presented, and the importance of short selling practices is examined by comparing different asset allocation strategies. A new methodology based on the positive and negative potential for the price (or return) on the next day is...
