The Active-Passive Debate: Bear market Performance:
There is no evidence that active managers on average are able to produce better performance than index fund during bear market.
The paper also found that outperformance in one bear market has no relation to outperformance in subsequent bear markets. Indicating that fund that outperformed in one market is most likely due to luck rather than skill.
You will always find mutual fund that outperform the index in any particular year, jus like there is always a chance of rolling a die and get a value of more than 3.5. The question is how to find the funds that will outperform in the future? Certainly not by looking at how they did historically.
Based on the
2022 mid-year SPIVA persistence score card, out of the 489 funds in the 2020 top quartile, NOT A SINGLE fund remains in the top quartile in the next 2 years. Other studies have similar results, top performing funds today don't stay at the top.
The paper,
On Persistence in Mutual Fund Performance, also looked at persistence of mutual fund and has a damning remark:
The results do not support the existence of skilled or informed mutual fund portfolio managers.
Paraphrasing Ben Felix, head of research at PWL, if you are rich and want to gamble on an actively fund beating the market, go ahead. But if you are average household saving/investing for retirement or other financial goals, there's really no reason in investing mutual fund for that tiny chance of outperformance.
