Abstract

We review a resent time-dependent performance measure for economical time series -- the (optimal) investment horizon approach. For stock indices, the approach shows a pronounced gain-loss asymmetry that is not observed for the individual stocks that comprise the index. This difference may hint towards an synchronize of the draw downs of the stocks.
