Short selling ETFs and market performance

Journal of Financial Research, EarlyView.
Abstract We examine short selling activity in leveraged Exchange‐Traded Funds (ETFs) and its impact on underlying index performance. Using a novel measure of ETF short exposure, which includes long positions in inverse leveraged ETFs, we document that high short exposure is associated with positive performance in the subsequent period.

Model of regulation of Spx and yirB under cell wall stress.

, 2018
(A) Model of induction of the Spx regulon under cell wall stress. In exponentially growing cells (before induction), spx is constitutively expressed but Spx is actively degraded by the coordinated action of YjbH (i.e. the adaptor protein) and ClpXP (i.e.

Spx system at a single‐cell level

, 2023
Spx is a global transcriptional regulator that orchestrates the Bacillus subtilis response to disulfide stress. The YjbH (SpxH) protein adapts Spx for ClpXP-mediated degradation, playing a critical role in the regulation of the cellular Spx levels.

A prospective study of the incidence of myocarditis/pericarditis and new onset cardiac symptoms following smallpox and influenza vaccination. [PDF]

PLoS ONE, 2015
Although myocarditis/pericarditis (MP) has been identified as an adverse event following smallpox vaccine (SPX), the prospective incidence of this reaction and new onset cardiac symptoms, including possible subclinical injury, has not been prospectively ...

Risk, Specialization, and Covered‐Interest Parity

The Journal of Finance, EarlyView.
ABSTRACT Prevailing theories of financial intermediation assume an integrated financial sector with frictionless risk‐sharing. However, we identify substantial risk‐sharing frictions linked to intermediary specialization using currency derivatives markets as a laboratory. Using confidential supervisory data covering $25 trillion in daily bank exposures,

Use-dependency of SPX on I_CaL.

, 2016
A, Repetitive application of depolarizing pulses (shape is shown in the figure inset) to 0 mV from a holding potential of −50 mV gradually decreased the ICaL amplitude. The frequency of depolarizing pulses was 2 Hz.

On Short‐Term Behavior of Implied Volatility for Index Options

Mathematical Finance, EarlyView.
ABSTRACT This paper investigates short‐term behavior of implied volatility of derivatives written on a market index when the index is constructed using a ranking procedure. Even when stock prices follow geometric Brownian motion dynamics, the ranking mechanism can lead to the observed term structure of at‐the‐money (ATM) implied volatility skew for ...

Effects of N-acetylcysteine on spexin immunoreactivity in kidney tissues of rats treated with adriamycin [PDF]

Iranian Journal of Basic Medical Sciences
Objective(s): Due to its negative side effects, mainly nephrotoxicity, adriamycin (ADR) is used fairly infrequently. The purpose of this study is to investigate the effects of N-acetyl cysteine (NAC) on the immunoreactivity of spexin (SPX) in the kidney ...

Inositol pyrophosphate dynamics reveals control of the yeast phosphate starvation program through 1,5-IP8 and the SPX domain of Pho81

eLife, 2023
Eukaryotic cells control inorganic phosphate to balance its role as essential macronutrient with its negative bioenergetic impact on reactions liberating phosphate.
