Crash-Neutral Currency Carry Trades

Currency carry trades exploiting violations of uncovered interest rate parity in G10 currencies deliver significant excess returns with annualized Sharpe equal to or greater than those of equity market factors (19902012). Using data on out-of-the-money foreign exchange options, I compute returns to crash-hedged portfolios and demonstrate that the high returns to carry trades are not due to peso...

5 Carry Trades and Currency Crashes

This paper studies crash risk of currencies for funding‐constrained speculators in an attempt to shed new light on the major currency puzzles. Our starting point is the currency carry trade, which consists of selling low interest rate currencies—“funding currencies”—and investing in high interest rate currencies—“investment currencies.” While the uncovered interest rate parity (UIP) hypothesize...

Detecting Abnormal Behaviors in Crowded Scenes

Situational awareness is a basic function of the human visual system, which is attracting a lot of research attention in machine vision and related research communities. There is an increasing demand for smarter video surveillance of public and private space using intelligent vision systems which can distinguish what is semantically meaningful to the human observer as ‘normal’ and ‘abnormal’ be...

Detecting stars in crowded stellar fields

A comparison is made between some conventional and new methods for detecting stars in crowded stellar images. The new methods are (1) Lucy-Richardson deconvolution of the image before detection, and (2) fitting the Point Spread Function to each pixel in the image. These methods are applied to both a synthetic image and a real one. The deconvolution method looks very promising, and gives better ...
