Discretionary managers use fundamental analysis to select stocks and construct portfolios that seek to beat the market. These managers face substantial headwinds in the current environment. From a business perspective, they are under pressure to reduce cost and improve performance. The market environment has also been challenging, as high correlations between stocks and the dominance of a handful of large technology companies have made it harder to generate alpha from stock selection.

These companies have been underrepresented in most factor-based strategies due to their unattractive factor characteristics. Have factor investors suffered from not investing in these stocks?

Growing fears about rising inflation and interest rates sparked a decline across equity markets in the last few days.
