Sharpe ratio is a measure of excess return earned by investment per unit of total risk. It is calculated by dividing excess return (which equals return minus risk free rate) by standard deviation of the investment returns.Investment management requires a trade-off between risk and return. ...
Significant out-of-sample sign predictions are obtain with respect to the Pesaran-Timmerman test for directional accuracy, while trading on the Sharpe Ratio allows to improve the risk adjusted return.doi:10.1142/9789812776655_0003Dept.

Return on capital employed is a financial ratio that measures a company’s profitability in terms of all of its capital. It's a ratio: earnings before interest and tax (a.k.a. operating income) per capital employed. A higher ratio indicates that a company is profitable. ...

The Switch_et portfolio generates a higher average return, Sharpe ratio, Omega, and Sortino ratio than the B&H portfolio. The Switch_et portfolio has lower standard deviation, maximum drawdown, and risk measures (value-at-risk (VaR) and expected shortfall (ES)). Notice that the B&H portfolio...
gradients of C6 and C12 overlapped but the C12 gradient could extend further due to C12 being actively produced by a large region of cells (Fig.4d). At a certain distance from the source of C6, the ratio of C12 to C6 favoured the C12 state such that the bistable switch ‘flipped’ ...
Cognitive biases are found to play a role in the onset and maintenance of social anxiety. However, particularly in adolescence, the link between different biases and their role in predicting social anxiety is far from clear. This study therefore investigated the interplay between attention bias and...
DcMichele & Sharpe (1973) termed the phenomenon the mechanical advantage of the epidermal cells, while Cooke et al. (1976) expressed it as an antagonism ratio. Both of these formulations, however, have theoretical or practical limitations. This study presents a biophysical analysis demonstrating ...
