Mirando ALFA he visto esto:
The Index can vary from being 100% long to up to 50% short, also known as “market hedged,” based on market volatility targets defined by the methodology. The Index, and therefore the Fund, may take a defensive position and become market hedged (i.e., short) if one or more broad-based market indices close below their respective 200 day moving average at the end of any month. Short positions are used to hedge long positions and to seek positive returns.
Mi pregunta es... realmente sirve de algo esa estrategia?
