Hi Simone, thanks for your question. No, I don't believe we can state with certainty that factor investing will continue to generate excess returns. However, what's the alternative? Active management is not a solution as most fund managers underperform regardless of the time frame (please see the S&P SPIVA scorecards). For most investors therefore the best choice is simply beta via a cheap ETF, but if an investor is required to generate outperformance, then factor investing remains the best bet.
