Optimal VWAP trading under noisy conditions

This article proposes an empirically tractable way to incorporate intra-day noise into a VWAP trading rule. In volatile markets, news arrives unexpectedly and rapidly. This should influence a trader's trading decisions. However, the literature has not incorporated such information into an algorithmic trading framework. Subsequently, this paper presents a Dynamic VWAP (DVWAP) framework that allows informed traders to utilize random news; and thus, improve trade-execution.VWAP strategies Algorithmic trading Intra-day volume

Firm size, takeover profitability, and the effectiveness of the market for corporate control: Does the absence of anti-takeover provisions make a difference?

The market for corporate control is generally regarded as an important disciplinary mechanism in well developed economies. Entrenchment mechanisms commonly used by US firms in the form of anti-takeover provisions (ATPs) may offer some protection from disciplinary action, facilitating entrenchment and value-reducing behavior. One manifestation of entrenchment is poor acquisitions, with the literature reporting significant losses to large acquirers, and to acquirers with a higher number of ATPs. We examine the profitability of acquisitions in Australia, a market where US-style ATPs are prohibited. The results show that unlike their US counterparts, large Australian acquirers earn significant value for their shareholders, both in terms of announcement returns and long-run operating performance improvements. Takeover premiums are also substantially lower than those reported for the US and UK, and do not differ between large and small acquirers. Premiums are also positively correlated with long-run operating performance, indicating that they reflect real synergies, as opposed to hubris or overpayment. We also find that bidders who destroy value in takeovers are likely to be subsequently acquired. However, unlike US evidence, larger acquirers are just as likely to be targeted for takeover as smaller acquirers, indicating that size is not an effective impediment to the disciplining function of the market for corporate control in Australia. The findings are robust to several econometric issues common to the type of models used in our analysis.Size effect Corporate control Takeovers Empire building Entrenchment
