Skew Premiums Around Earnings Announcements

Financial Review, EarlyView.
ABSTRACT We examine skew premiums in equity options around earnings announcements. We use the realized returns to delta‐neutral risk reversal option spreads as a proxy for the skew premiums. We find skew premiums are economically significant around earnings announcements and are not explained by changes in variance risk premiums.

Histological characterisation of gonadal sex differentiation in Malabar red snapper (Lutjanus malabaricus) for aquaculture advancement

Journal of Fish Biology, EarlyView.
Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...

The GmGT‐2F, a trihelix transcription factor, regulates seed oil content by directly activating GmAGAL transcription in soybean

Journal of Integrative Plant Biology, EarlyView.
In soybean, the trihelix transcription factor GmGT‐2F positively regulates the expression of the α‐galactosidase gene GmAGAL, thereby modulating seed oil content. The cyclophilin GmCYP2 interacts with GmGT‐2F and suppresses GmAGAL activation. Haplotype diversity analysis of GmGT‐2F, GmCYP2, and GmAGAL identified favorable haplotype combinations ...
