Most investors who have not seen protracted market falls should not be too ambitious with their return expectations. The last meaningful fall that persisted was 16 years ago, and every rally since then has been bought into, due in large part to unconventional central bank policies. The time for those policies might well be up, no matter how much the fund managers and market experts want to hold hopes for rate cuts and resumption of the perma-rally.
Unfortunately, many of the young and new investors have no context of how markets behave in the absence of excessive money printing, which has continued for long now. And it is easy to assume that money made investing in recent years has been because of the brilliance of the fund managers/investor's strategy, while it has largely been a one-way street if one has been diversified enough.
