We examine information content and related insider trading around private in-house meetings between corporate insiders and investors and analysts. We use a hand-collected dataset of approximately 17,000 private meeting summary reports of Shenzhen Stock Exchange firms over 2012–2014. We find that these private meetings are informative and corporate insiders conducted over one-half of their stock sales (totaling $8.7 billion) around these meetings. Some insiders time their transactions and earn substantial gains by selling (purchasing) relatively more shares before bad (good) news disclosures while postponing selling (purchasing) when good (bad) news is to be disclosed in the meeting. Finally, we conduct a content analysis of published meeting summary reports and find that the tone in these reports is associated with stock market reactions around (1) private meetings themselves, (2) subsequent public release of private meeting details, (3) subsequent earnings announcements and (4) future stock performance. 相似文献

We consider structure preserving measure transforms for time-changed Lévy processes. Within this class of transforms preserving
the time-changed Lévy structure, we derive equivalent martingale measures minimizing relative q-entropy. They combine the corresponding transform for the Lévy process with an Esscher transform on the time change. Structure
preservation is found to be an inherent property of minimal q-entropy martingale measures under continuous time changes, whereas it imposes an additional restriction for discontinuous
time changes. 相似文献

The Islamic capital market is an important component of the overall Islamic financial system especially in providing an element of liquidity to the otherwise illiquid assets. Like its conventional counterpart, Islamic capital markets complement the investment role of the Islamic banking sector in raising funds for long-term investment. These long-term investments are facilitated through various Shariah contracts and instruments ensuring efficient mobilisation of resources and their optimal allocation. This article aims at reviewing equity-based Sukuk structure, which is one of the most popular instruments used in Islamic capital market today. This article argues that some innovations made in structuring Sukuk, which try to achieve the same economic outcome like conventional instruments, distort the vision of Islamic economics based on justice and equitability. These visions are deeply inscribed in the objectives of Shariah, also known as Maqasid al-Shariah. This distortion stems from the restricted view of understanding Shariah, by only focussing on the legal forms of a contract rather than the substance especially when structuring a financial product. The overemphasis on form over substance leads to potential abuse of Shariah principles in justifying certain contracts, which in fact are contradictory to the Shariah text and ultimately undermining the higher objectives of Shariah. In the final analysis, this article concludes that the substance of a contract that has greater implications to the realisation of Maqasid al-Shariah should be equally looked into. Otherwise, Islamic finance just appears as an exercise of semantics; the functions and operations are really no different from conventional banks, except in the use of euphemisms to disguise interest and circumvent the many Shariah prohibitions. 相似文献

Policymakers around the world call for more competition in the banking sector. One prerequisite to achieving this is customer mobility. Despite its policy relevance, surprisingly little is known about consumers’ bank switching behaviour. We show that the principal reasons to stay at one’s bank are a good bank-customer relationship, practical barriers, and the perception that there is not much benefit in switching. Moreover, we find that the reported propensity to switch varies across banking products. For the main current and savings accounts, this propensity is most strongly related to the bank-customer relationship, while for mortgage loans it is especially linked to switching experience. These findings have important implications for antitrust policy; they provide an argument against using a cluster-based legal standard for the analysis of competition and in favour of a disaggregated approach. Regarding the effectiveness of hypothetical policy initiatives to lower switching barriers, we find that the reported switching propensity with current accounts is higher in the case of account number portability, while more knowledge of the existing switching service has no significant effect. Lastly, scenario analysis shows that a policy of allowing new foreign banks to enter the savings market is less promising for enhancing mobility than a policy that increases the number of domestic players. 相似文献
