Variance swap volatility dispersion [PDF]

open access: yesDerivatives Use, Trading & Regulation, 2006
Several trading institutions are actively engaged in ‘volatility dispersion’ strategies. These involve selling volatility on the index and buying volatility on the components. This trade was traditionally done using at the money (ATM) straddles. An important practical problem with this approach is that market prices move and cause the original ATM ...

Engineering the Link: From Genome Interaction Maps to Functional Insight

open access: yesAdvanced Biology, EarlyView.
Advances in chromosome conformation capture have revealed the genome's 3D organization, yet its causal impact on gene regulation remains elusive. This review highlights emerging genome‐engineering tools ‐ zinc fingers, TALEs, and CRISPR‐Cas9 ‐ that enable targeted manipulation of chromatin loops to dissect structure–function relationships. It discusses
