How to construct an index fund

There are three main methods for constructing an index fund.

Perfect law
Stock indexA method to buy and sell all the stocks that make up the stock according to the index composition ratio. Since it has the exact same structure as the index, it is highly linked to the index. A certain amount of assets is required to invest according to the index composition ratio. Trading costs are high because trading occurs every time the index is changed or the ratio is changed.
Extraction method
A method that aims to link to the index by buying and selling only a part of the stocks that make up the index. Compared to the perfect method, there are fewer issues to hold, so trading costs are less likely to occur, and it is easy to build a fund even with small asset amounts. On the other hand, the difference between the index and the constituent stocks or the constituent ratio causes the tracking error.
Synthetic replication
In kindDerivativesA method of combining transactions and aiming to link to the index.A method of filling the gap between the cash stock basket and the index that occurs due to stock replacement or change of ratio with derivatives.

Tracking error and its cause

Tracking error is an index that indicates how far the price movements of index funds and portfolios in index investment deviate from the target index. It is expressed as the standard deviation of the return of the fund or portfolio and the price movement of the index, and is used as an index of the risk of the index fund.

The main causes of tracking error are

  1. Trading time discontinuity
  2. Trading unit discontinuity
  3. Operating costs

Is mentioned.

Regarding 1., when it becomes necessary to buy or sell a constituent stock due to fluctuations in the weight of the constituent stocks or the movement of cash due to the addition or cancellation of a fund, ideally, the trading should be repeated each time to create an ideal configuration. It would be good if it could be a ratio, but in reality it is impossible in terms of trading fees.Therefore, by trading only at a specific time, a deviation from the ideal composition ratio will occur.

Regarding 2., when the constituent stocks are weighted on the net assets, a fraction is generated for the trading unit of the stocks.For this reason, instead of adopting index weighting as it is (called the perfect method), a method of optimizing the weighting of stocks so as to reduce the deviation from the fund's assets (called the optimization method). Is often used.

Regarding 3., the actual operation costs (trading fees, trust fees, taxes) are deducted from the assets of the fund.This amount can be confirmed by the actual results of the operation report and the prospectus.

Index fund types

Index funds are so-called unlisted investment trusts in a narrow sense, and index-linkedListed investment trustThere are two types. Usually, only the former is called an index fund.
