This paper examines the out-of-sample performance of thirteen portfolio strategies in the Spanish financial market (Ibex 35) during the COVID-19 pandemic (considering four different periods) by using three standard financial metrics. The main findings of the study are as follows: (i) the only methods outperforming Ibex 35 are those based on risk parity or diversification; (ii) unstable period data caused underperformance of strategies that require a previous estimation of certain hyper-parameters in their formulations.
