"It will be sent out for so-called final notification this week", writes prosecutor Pontus Hamilton about the preliminary investigation in an email to TT.
Suspects of gross insider crime
He adds that potential prosecution can be brought "at the beginning of next year".
The evidence has not weakened during the unexpectedly prolonged preliminary investigation, on the contrary, according to Hamilton.
"We are finished with the investigation", he writes.
"All are suspected of gross insider crime", he adds.
After final notification, new elements may be added to the process before a decision on prosecution. Among other things, the prosecutor can request additional information, which may lead to the establishment of a supplementary protocol.
It may also be requested that the legal representatives of the suspects provide more information, which may need to be investigated.
The Economic Crime Authority (EBM) notified the four suspects of gross insider crime in the fall of 2023 after a raid on the Nasdaq Stockholm Stock Exchange.
Fines of 100 million
The handling of the case has also caused problems for Nasdaq. The American stock exchange operator was fined 100 million kronor last summer following a sanctions decision by the Financial Supervisory Authority (FI), as Nasdaq had not reported the suspected transactions.
The suspected transactions were made in trading with shares in Ica, Swedish Match, and Haldex prior to bids on the affected companies. And they were reported by banks.
According to FI, there were "clear deficiencies in the exchange's trade surveillance" that meant the insider trading was never reported.
