Portrait of Harlan F. Stone Harlan F. Stone Provost v. United States — Opinion of the Court

Even in a loose and colloquial sense it cannot be said that the loan of stock is a 'deposit of stock certificates as collateral security for money loaned thereon.' We therefore conclude that while there is no indication of a purpose to impose a discriminatory tax upon short sales or transactions necessarily involved in short sales, there was a general purpose to tax all transfers of legal ownership of shares of stock which includes those made necessary in order to complete a short sale.

But the borrower of stock holds nothing for account of the lender. The procedure adopted and the obligations incurred in effecting a loan of stock and its delivery upon a short sale neither contemplate nor admit of the retention by either the borrower or the lender of any of the incidents of ownership in the stock loaned. The seller, having contracted to sell securities which he does not own, is under the necessity of acquiring dominion over stock of the kind and amount which he has sold, with unrestricted power of disposition of it in order that he may fulfill his contract.

The loan of stock is usually, though not necessarily, incidental to a 'short sale.' As the phrase indicates, a short sale is a contract for the sale of shares which the seller does not own or the certificates for which are not within his control so as to be available for delivery at the time when, under the rules of the Exchange, delivery must be made. Under the rules of the New York Stock Exchange, applicable so far as the facts of this case are concerned, a broker who sells stock is required to make delivery of the certificates on the next business day.
