The cost of turbos
More than 10 years ago, turbos were introduced in the Netherlands. Since then, they have rapidly grown into a popular investment product and their popularity continues to grow. In order to trade turbos effectively , it is wise to know how these products work, but also what costs are involved. These costs affect the result of your turbo investment. This article will clarify which costs you should take into account when investing in turbos.
When it comes to investing in turbos, there are 5 types of costs:
If you start investing in turbos, you should take into account a number of costs outside of the operation. The costs are listed below, after which they are analyzed in more detail.
- Financing costs
- Dividend leakage
- Risk premiums
- Spreads
- Transaction and other costs
1. The financing costs
The financing costs differ for a turbo long and turbo short . For this reason, the financing costs for both types will be explained separately.
Turbo long
When buying a turbo, the issuing party, for example a bank, finances the majority of the value of the underlying share . This financing involves interest costs, also known as financing costs. These have an impact on the final investment result and are therefore worth mentioning. To explain the financing costs a little more clearly, we have added an example below:
Example of financing costs
Suppose a share has a value of €500 and the financing level is €480. This means that the issuing party finances €480. The turbo is then worth €20. Interest is due on the €480 that is financed by the issuing party (such as a bank). The interest to be paid is passed on in the value of the turbo.
Turbo short
A low interest rate causes a strange situation for turbos short. With turbo short, it is normally the case that there are financing proceeds. These are equal to the short interest minus a surcharge. But due to the low (and sometimes even negative) interest, there are costs instead of proceeds. These costs are then even higher than the financing costs on turbos long.
The above explanation and example show that it is important to have a good insight into the size of the financing costs.

2. Dividend leakage
The dividend payments are automatically included in the amount of the financing level of the purchased turbo. Received dividends have no effect on the price of the turbo. It is true that received dividends result in a lower price, but due to a simultaneous reduction in the financing level, this has no effect on the turbo price: it remains the same. Please note: this only applies if the entire dividend is passed on in the financing level.
The calculation of the entire dividend does not always occur. The reason for this is that a withholding tax of often 15% is calculated on dividend. The issuing institution, such as a broker or bank, can reclaim the withholding tax itself. It is then almost always possible to settle the entire dividend at the financing level.
This is often different for foreign shares. In that case, the withholding tax cannot be reclaimed. This is called dividend leakage. Another point of attention is the limited dividend calculation with turbo short. You would think that the limited calculation would yield a nice advantage with turbo short. This is not the case. With turbo short, the full dividend amount is always calculated – whether or not there is dividend leakage.
3. Risk premium
What happens in the event of a large price drop in the value of the underlying share? In that case, the investor runs the risk of losing the investment. The issuing party, such as the bank or the broker, only runs the risk when there has been a very large price drop. In order to absorb such a sudden price drop, there is a safety buffer. This is the difference between the ‘stop loss’ and the financing level. The issuing party determines this buffer. The larger the buffer, the less risk the issuing party runs. In general, issuing parties charge a small buffer via higher financing costs.
The risk premium is determined by the price expectation of the underlying share. Based on this, a high or low premium is chosen.

It is good to know that a high premium does not immediately mean that the return is reduced by the amount of that premium. When the investor sells the turbo and the premium at that time is as high as when the product was purchased, the investor collects the previously paid premium. This is not the case when the ‘stop loss’ level is broken. In that case, the investor loses the previously paid premium.
4. Spreads
When you are active in this market, you are regularly busy buying and selling your position. Buying turbos is done at the ask price; selling at the bid price. The closer these prices are to each other, the more it yields for the investor.
5. Transaction and other costs
When trading turbos, there are also transaction costs that you have to take into account. Sometimes there are also storage costs and other costs that you owe to your broker or bank. These costs depend on the bank or broker you are affiliated with. To know exactly what and when you owe something, it is best to contact your broker or bank. These are costs that simply count towards the final result of your trading in turbos.
The conclusion of the costs of turbos
The final costs of (trading with) turbos are a determining factor for the final result. That is why it is good to take the possible costs into account in advance. By knowing in advance what influences the costs of turbos, comparing brokers becomes a lot easier. The height of the costs will differ per broker, so compare all brokers with turbo possibilities and find the broker that suits you!
