Parqet records stock splits (with and without a change of ISIN/WKN), fusions, merges and spin-offs centrally for all portfolios, even if they happened in the past. You don’t need to book them yourself. This matters because brokers often don’t provide complete documents for them, for example without the entry price (your price per share, excluding fees).
​

In a stock split, the number of outstanding shares is increased or decreased. For example, in a 1:4 stock split, all shareholders receive three additional shares for each original share they hold, so that they have four shares after the split. However, the market value of the shares is divided over the previously invested capital in such a way that it’s a zero-sum game.

Stock split example:

Before a 1:4 stock split: 1 share at €100 each = total capital of €100.

After a 1:4 stock split: 4 shares at €25 each = total capital of €100.

This also works the other way around and is called a reverse split. In a 4:1 reverse split, all shareholders receive one new share for every four shares they hold, so that only one share is left after the split:

Reverse split example:

Before a 4:1 reverse split: 4 shares at €25 each = total capital of €100.

After a 4:1 reverse split: 1 share at €100 each = total capital of €100.

Stock splits are often used when the price of a single share has risen too high, while reverse splits are used when the price of a single share has fallen too low.

First of all: you don’t need to, and must not, enter share prices adjusted for splits after the fact. Specifically: if you bought Amazon in 2020, you paid €2,000 per share (the actual price at the time) and not €100 (today’s split-adjusted price). In each activity, enter the value at the time, i.e. the value shown on your trade confirmations. If you’re switching to Parqet as a Portfolio Performance user, this historical accuracy no longer exists (in German) and you’ll first need to restore your activities.

Parqet currently distinguishes between two forms of stock splits and reverse splits. In the first form, the security’s ISIN or WKN (identification numbers) stays the same. From the user’s point of view, the split is applied directly to the existing holding and is visible there. In the example below, Monster Beverage carried out a 1 to 2 split (1:2).

In the second variant, the security’s ISIN or WKN has changed. Parqet then shows the old and the new security as two separate holdings: the old security is automatically transferred out and the new one is transferred in.

Your previous activities, realized gains and dividends stay on the old holding. In the web app, under “Activities”, the “ISIN change” entry has a link “To new holding” or “To old holding”.

Did we miss a stock split? Please let us know so we can quickly apply it centrally to all portfolios. Send us a message via our contact form (topic “Data (Prices, News, Logos, Sectors)”) with the date, the split ratio and a link to a news article about the split. We’ll then add it as soon as possible.

We generally have duplicate detection in place for this. If we detect a transfer in, we don’t create the split transfer in again. If we don’t detect one, we create the split transfer in.

If you end up with a duplicate, delete the activity you entered manually and adjust our automatically created activity if necessary.

Don’t worry, you can change the entry price and the number of shares of the automatically created stock split transaction. To do this, go to the automatically created activity and change “Price” and “Shares” accordingly.

Parqet records fusions and merges centrally, just like stock splits. Parqet’s definitions partly differ from the terms commonly used for various transactions.

A fusion is when security A and security B become a new share C. One example of a fusion was Shell in 2022, when Royal Dutch Shell A and Royal Dutch Shell B were combined into a new Shell share.

A merge is when security A and security B are combined and either security A or security B remains. This happens with ETF mergers, for example.

Did we miss a merge (e.g. an ETF merger) or a fusion (e.g. securities being combined, as with Shell)? Please let us know so we can quickly apply the corporate action centrally to all portfolios. Send us a message via our contact form (topic “Data (Prices, News, Logos, Sectors)”) with the date, the exchange ratio and a link to a news article about the corporate action. We’ll then add it as soon as possible.
​

We generally have duplicate detection in place for this. If we detect a transfer in, we don’t create the automatic bookings again. If we don’t detect one, we create them.

If you end up with a duplicate, delete the activity you entered manually and adjust our automatically created activity if necessary.
​

Don’t worry, you can change the entry price and the number of shares of the automatically created transactions. To do this, go to the automatically created activity and change “Price” and “Shares” accordingly.

In a spin-off, a business unit of a parent company is separated out and becomes an independent company. For example, in 2024 the industrial group 3M spun off its healthcare business Solventum. This company was booked into 3M shareholders’ brokerage accounts as a separate share.

Parqet automatically books spin-offs into your portfolios. In the spin-off of Solventum from 3M, every 3M shareholder received one Solventum share for every 4 shares of 3M. In the example below, the shareholder only had one 3M share in the portfolio and accordingly received 0.25 shares of Solventum.

Clicking “3M Press Release” takes you to the press release in which 3M described the spin-off in detail. “4 to 1 Spin-off” shows the spin-off ratio mentioned above.

In the example above, a single 3M share was bought at a price of €85. Accordingly, the invested capital is also €85. After the spin-off, this invested capital is split proportionally with the new company Solventum.
​

Before: 1x share at €85.00 (1x 3M).

After: 1.25x shares at a total of €85.00 (1x 3M, 0.25x Solventum = 1.25).

These €85 are now divided across the new number of 1.25 shares. This results in a new entry price of €68 per share (€85 / 1.25 = €68). So Parqet splits your invested capital by the number of shares, not by the market value of the two stocks. Every share, old and new, gets the same entry price.

If you’re an existing Parqet user and used a workaround in the past to get the correct entry prices, you can delete the activities you created yourself.

In this case, we don’t book the new share into your portfolio to avoid creating duplicates. If you delete your original transfer in, we automatically create the spin-off activity. To do this, Parqet looks for a transfer in of the new share in your portfolio up to 14 days before and after the spin-off. If Parqet doesn’t find one, it transfers in the new share.

If duplicate detection doesn’t work, the fix is just as easy: go to the activities of the relevant share and delete the activity you created yourself. Then, if you want or need to, correct the activity Parqet created automatically.
​

Yes. In the 3M spin-off, Solventum was booked into investors’ brokerage accounts. In Parqet, this transaction can’t be deleted, but it can be adjusted. You can change the price, the number of shares and the date of this activity. Further down in this article, we explain why this may be necessary or useful, along with a few example cases.
​

In a spin-off, Parqet splits your invested capital: the parent company’s entry value is distributed across its shares and the newly transferred-in shares. That’s why the new position doesn’t start at €0.00. However, banks book spin-offs in different ways (examples below), and some only adjust the entry prices later. So wait a while first.

If the entry price still differs significantly from your broker’s after a longer time, you can adjust it. Open the transfer in activity of the new security and enter the entry price at which your broker booked the shares as the price. Parqet then automatically adjusts the parent company’s entry price to the same extent.

Keep in mind that German banks generally disagree on how spin-offs should be handled. Here are some examples from selected German banks:

As part of the spin-off, the parent company’s entry prices are usually adjusted according to the calculation above. This also makes sense, because in addition to the entry price correction in portfolios, the historical price chart is also corrected:

In the 3M chart, January 2, 2024 shows a price of €83.88. However, 3M shares didn’t trade at €83.88 on that day. The price was corrected historically by a factor of 0.8584: with €83.88 as the base, the unadjusted price on January 2, 2024 was €97.71.

But banks disagree here as well.

Currently, it’s not possible to undo the entry price change for the parent company in Parqet. If you want to mirror your bank’s display in Parqet, you can, for example, transfer out the parent company’s security one day after the spin-off and transfer it back in at the bank’s entry price.
​

In this situation, too, you should wait a while first. Some brokers are slow to implement spin-offs. With the 3M spin-off, for example, it wasn’t unusual that not all brokers had correctly booked the spin-off into their users’ portfolios even after 7 bank business days.
​

Also check whether you missed a transaction from your broker:

In some cases, for example, fractional shares are first booked into the brokerage account and then automatically sold by the broker. In this case, there’s usually a trade confirmation from your broker. You can take the correct sale amount from it. With the PDF import or Autosync, we create this transaction based on your trade confirmation details.

In this case, your broker didn’t book any shares for you, but compensated you with a corresponding amount of money. This can happen if the share wasn’t tradable at your broker or if you were entitled to fractional shares that your broker doesn’t support.

Let’s say you held 5 shares of 3M and received €15.42 per 3M share as compensation from your broker, €77.10 in total. This happened with the 3M spin-off at the broker XTB, for example. For this, Parqet transferred in 1.25 Solventum shares for you (5 × 0.25).

If a spin-off was transferred in and you then sold all of it, the spin-off share appears under “Sold securities”. If it still appears among the securities you hold, for example as a small fraction, Parqet has usually calculated the spin-off “more precisely” than your broker. Parqet calculates fractions to 8 decimal places, while your broker sometimes cuts them off earlier.

In this case, change the number of shares of the spun-off share in the transfer in.
​

Here’s an example of the spin-off of Warner Bros., a spin-off from AT&T:

The spin-off was sold in the Scalable Capital brokerage account after the transfer in, but about 0.0008 shares were still “left over” in the Parqet portfolio. This is because the Scalable Capital sell document only shows 18.143 shares – but there were actually 18.143775 shares.

Number of shares in the trade confirmation:

Sell activity in Parqet:

In this case, click the sell activity and edit it.

Then click again here to apply the full number of shares:

Then save the activity with the correct number of shares. The correct number of shares is now recorded and the holding appears under the sold securities in your portfolio.

In rare cases, spin-offs come with a kind of rights trading, where the right to receive the spin-off is traded. If you buy additional rights, you’ll later receive more shares of the spin-off. If you sell your rights, you’ll receive fewer or no shares of the spin-off.

If you bought or sold rights and still receive at least a fraction of the spin-off, you can change the transfer in activity to the corresponding number of shares.

If you sold all your rights and are no longer entitled to the spin-off, you can cancel out the spin-off in Parqet with a “Transfer out” activity.
