Editorial
A neutral framework for reviewing investment trusts you hold, covering purpose, cost, holdings and distribution policy, plus tax and cost considerations when switching, with hypothetical figures.
Contents
Checking your investment trusts from time to time makes it easier to notice when they have drifted away from your purpose. A review, however, does not presuppose a switch. Concluding that you will simply keep what you hold is a perfectly reasonable outcome. This article sets out the points to look at when reviewing a fund, and the tax and costs to check if you do switch. It does not recommend any specific fund or timing for trades.
What a review involves
A review is the task of confirming whether the purpose and assumptions you had at the time of purchase still apply. Judging only by whether the price has gone up or down makes it easy to be swayed by emotion. Deciding in advance what you will check allows a calmer assessment.
There is no required frequency. Some people choose a fixed date once a year or twice a year. Looking at prices too often can make it easier to react to short-term moves, which is worth bearing in mind.
Main points to look at
Going through the following items helps organize the facts.
| Point | What to confirm |
|---|---|
| Fit with purpose | Whether the goal (retirement, education, housing) and time frame are unchanged, and whether the date of need is approaching |
| Cost | How the management fee and other costs compare with funds of similar content |
| Holdings | Whether the regions or asset types are lopsided, and whether they overlap with your other holdings |
| Management status | Any gap from the index it follows or any change in policy, as shown in the management report |
| Net assets over time | Whether the fund has become very small or keeps shrinking |
| Distribution policy | Whether the way distributions are paid still suits your purpose |
When checking costs, you can look at how a fee difference affects the long run. A Japanese-language tool, the compound interest calculator (Japanese), lets you enter slightly different rates to compare.
Costs and tax to check when switching
Switching means selling one fund and buying another, so several costs and taxes come into play.
- Tax on sale: in a taxable account, a gain is normally taxed at about 20.315%.
- Purchase fees: for funds that charge a sales commission, that amount is deducted from the start.
- Gap between sale and purchase: there can be a period when you are not invested, during which market moves are not reflected in your holdings.
- Redemption charges: some funds retain a certain amount when units are sold.
Hypothetically, suppose a fund is worth 3 million yen and was acquired for 2.4 million yen. The gain is 600,000 yen, and selling in a taxable account means tax of 121,890 yen (600,000 x 0.20315). If you moved to a fund whose annual fee is 0.5 percentage points lower, the saving would be 15,000 yen a year (3 million x 0.005). Even if all other conditions were identical, recovering the tax would take about 8.1 years (121,890 divided by 15,000). In reality, performance and other conditions change, so such a comparison is only a rough guide.
If the fund is held in a NISA account (Japan’s tax-free investment account scheme), gains on sale are not taxed. Even so, you should pay attention to how the allowance is treated and when it is restored, which is from the year after the sale. The rules can be revised, so please check the latest details with the Financial Services Agency or other official sources.
Organizing the keep-or-switch decision
The results of a review can broadly be sorted as follows.
- Purpose and content roughly match: keep the fund and set the date of the next review.
- Cost or content has drifted: estimate the tax and costs of switching and set them side by side with the result of staying put.
- The goal date is getting closer: consider whether to revisit the share of assets that swing widely in price.
- Unsure: a gradual approach, such as directing only new contributions to another product, is also possible.
Switching only because prices have fallen, or because another fund performed well, is often something people regret on reflection. Writing down the reason for each review helps keep decisions consistent. Our editorial policy describes how we try to present such frameworks neutrally.
Another way to keep a review manageable is to limit it to a short list of questions that you answer the same way each time. For example, you might ask whether the purpose is the same, whether the fees are still reasonable, whether the fund still holds what it says it holds, and whether any single region or asset has grown too large a share of the whole. Using the same questions makes it easier to see what has actually changed since the last review.
It also helps to separate the review of an individual fund from the review of the whole portfolio. A fund can be perfectly reasonable on its own and still be redundant if another holding already covers the same region or asset class. Listing everything you own in one table, with the region, asset type and cost of each line, makes overlaps and gaps easier to see than reviewing each fund in isolation.
Finally, keep in mind that doing nothing is also a decision. If the review shows no meaningful change, recording that result and the date is enough. The record becomes useful later, because it shows what you knew at each point and prevents the memory of a past decision from being rewritten by hindsight.
Points to consider and risks
- Past results do not indicate the future: another fund’s strong record does not mean it will continue.
- Switching has costs: once tax and fees are included, the outcome after switching can end up below what staying would have produced.
- Loss of diversification: replacing several funds over time can leave you concentrated in certain regions or assets.
- Avoid reacting to short-term moves: base reviews on your purpose, not on temporary price changes alone.
- No principal protection: any fund can fall below the amount invested.
A review is not about treating either keeping or switching as the right answer; it is a way to organize the grounds for a decision. After weighing both benefits and risks, the decision is yours. See also the disclaimer for the limits of the information here.
