We give an explicit algorithm and source code for combining alpha streams via bounded regression. In practical applications, typically, there is insufficient history to compute a sample covariance matrix (SCM) for a large number of alphas. To compute alpha allocation weights, one then resorts to...

This paper examines the funding liquidity faced by hedge funds and the resulting implication for stocks' excess return co-movement. We find that hedge fund ownership tends to induce a higher stocks' return co-movement with each other, compared to other institutional investors like mutual funds...

Hedge Fund returns are often highly serially correlated mainly due to illiquidity exposures given that investments in such securities tend to be inactively traded and associated market prices are not always readily available. Following that, observed returns of such alternative investments tend...
