Two Fund Veterans Debate Whether Hands-Off Investing Really Works

- Hideo Shirota, the figure behind the Orukan global index fund, sits down with Haruhiro Nakano, known as the 'installment prince'.
- The two debate whether a hands-off investing approach holds up.
- They cover US equities, gold as an allocation, and what to do through prolonged downturns.
Two questions dominate any long-term investing discussion: whether to leave a portfolio alone, and whether to concentrate on US equities. Japan's asset management industry put both on the table, with Hideo Shirota, the figure behind the global equity index fund known as Orukan, alongside Haruhiro Nakano, dubbed the "installment prince".
They represent two routes to the same destination. The index side argues for outsourcing stock selection entirely, buying the whole market at the lowest possible cost, leaving investors only to keep contributing and not to bail out. The installment side stresses discipline and rhythm — fixed amounts at fixed intervals, spreading entry prices over time so falling months become accumulation rather than panic. Both fight the same opponent: the investor's own emotions.
What travels best is how they frame the question. Whether hands-off investing works is not settled by comparing returns; it depends on whether you can genuinely do nothing through a prolonged slump. That requires money you will not need for years, and an allocation that does not force you to sell on the way down. Gold belongs in the same frame: its value depends on the role it plays in your portfolio, not this year's move.
The failure mode is behavioural, not analytical — stopping contributions after a few bad months, or adding beyond your tolerance when statements look good.
