Definitions

  • the present invention relates to methods, systems, and non-transitory computer readable recording media that support short selling of securities.
  • Securities lending and borrowing transaction means a securities consumption lending agreement concluded by the lender undertaking the transfer of ownership of the securities to the borrower and the borrower undertaking the return of the same amount of securities. Once a loan is established, the securities' disposal rights and revenue streams are transferred to the borrower, who then pays back the borrower's rights (e.g. cash or stock dividends, free shares, Compensation, etc.).
  • the securities' disposal rights and revenue streams are transferred to the borrower, who then pays back the borrower's rights (e.g. cash or stock dividends, free shares, Compensation, etc.).
  • Lending has been used to achieve a variety of purposes. Specifically, short selling transactions, arbitrage transactions through short selling, and collateral are used as collateral. transaction, a fail coverage transaction, a recall coverage transaction if a request for recovery of an existing loan transaction is received (recall coverage transaction), a lower fee It is used for the purpose of replacing a balance with a balance (refinancing transaction), and replacing the balance of the existing balance with a more stable balance.
  • the loan confirmation includes personal information about the lender and the borrower (e.g. the name of the institution, contact information of the institution and the person in charge), information on the stock to be borrowed (e.g., the name of the item, the quantity of the loan, etc.), and the time the contract was concluded (time stamp and trade date, settlement date, other related matters (e.g., whether to recall on stock dividends), and a unique identifier that identifies a firm contract. If a short sale is made without a loan statement when the securities are not borrowed through a loan transaction, this is called naked short selling and is strictly prohibited in most countries that allow short selling.
  • short selling consignor If the person who intends to make a borrow short selling (hereinafter referred to as "short selling consignor") intends to settle with borrowed securities for a borrow short selling order, the short selling consignor shall pay the securities prior to submission of the order. You must have already borrowed or have established a loan agreement.
  • the short selling consignor may, prior to submitting a borrowing short order, to provide proof of borrowing, from the lender: 1 the item and quantity of the loan securities, 2 the date and time of the settlement of the individual loan agreement, and the date of the individual loan transaction, 3 the personal details of the lender (eg, Your name, address, contact information, etc. will be asked to confirm your intention to rent.

  • the balance sheet it is possible to alter the balance sheet.
  • the information submitted is subject to at least one formatting and filtering of the information in the format required by the financial authorities. This is due to the fact that different institutions record information differently. Even if the relevant information is not processed in this process, it is almost impossible to check whether the contents of the balance sheet (eg, time stamp, quantity, amount, contract date, execution date) have been manipulated. This manipulation can occur not only in the audit process, but also in the usual balance sheet and short selling transactions. Borrowing short-selling transactions can lead to serious unsettled situations that are not recognized or post-traded.
  • a third party such as a consignment trader, securities depository, stock exchange, or financial monitoring / supervision organization that processes orders, clearly verifies borrowing (or lending) by the borrower (or lender). There is no way to do it. In the process of checking whether a short seller is a borrowed short seller from the short selling consignor, it is impossible to clearly verify whether the short seller is a short seller. Currently, the short seller trusts only the claim that the consignor has borrowed and is forced to process the short selling order. In addition, sharing the balance sheet with these third parties will inevitably reveal confidential business information between the borrower and the lender.
  • the above-mentioned problems cannot prevent the alteration of the balance sheet, the generation of irreversible information on the balance sheet record, such as the generation, transmission, and storage of the balance sheet, and the short selling order of the person who intends to short-sell (or intends to sell). This is due to the limitations of the current technology that cannot be verified by third parties without the disclosure of confidential information on whether all borrowings are secured and whether the lender is able to borrow.

Abstract

L'invention concerne, selon un aspect, un procédé de prise en charge de vente courte de titres commercialisables comprenant les étapes consistant à : générer des premières informations d'opération irréversible sur la base d'informations à protéger qui sont incluses dans des informations de transaction de prêt spécifiées en référence à un accord de conditions de transaction de prêt, passé entre un nœud de prêteur et un nœud d'emprunteur, pour le prêt de titres commercialisables ; générer des deuxièmes informations d'opération irréversible sur la base des premières informations d'opération irréversible et d'informations à ne pas protéger qui sont incluses dans les informations de transaction de prêt ; et mettre en correspondance au moins les unes des premières informations d'opération irréversible, des deuxièmes informations d'opération irréversible et d'informations d'algorithme liées à une opération irréversible à des informations d'ordre de vente courte liées aux informations de transaction de prêt.
