  • information embedded in option prices evidence from credit rating agency announcements
    2019
    Co-Authors: Mehdi Khorram, Gary C Sanger
    Abstract:

    We employ the implied volatility spread (IVS) as a measure of the information content of options, and confirm that IVS has the ability to predict future daily stock returns. We then focus on credit rating announcements and find that IVS has significantly higher predictive power on Event days versus non-Event days. In a consistent set of results we find that IVS predicts the direction and magnitude of credit rating changes. Exploring the source(s) of this predictability we argue it is driven primarily by short-sale activities. We find evidence against the hypotheses that IVS predictive power is driven by informed trading in options or by liquidity effects. These findings suggest that traders with information about credit rating announcements prefer to trade in the short-sale market rather than the options market.

  • ARM-based thin virtual desktop client integrating electrical power control with monitor
    2015 17th International Conference on Advanced Communication Technology (ICACT), 2015
    Co-Authors: Seong-woon Kim
    Abstract:

    This paper proposes an ARM-based thin virtual desktop client integrating electrical power control with monitor. User can turn on/off both of client and monitor using one monitor power button. This client consists of client power controller and ARM-based virtual desktop client. The client power controller performs integrated power control. The controller detects Power-on and power-off Events of the monitor and controls power of the client. For Power-on Event, the client power controller turns on directly the power line of the client. For power-off Event, the controller controls both of the power line and power management SW module of the client. The size of the client is compact and mountable to backside of the monitor with VESA mount.
