by John Marshall Harlan, Sigafus v. Porter — Opinion of the Court
“ In the last-named case-which was an action to recover damages for deceit in the sale of shares of stock in a mining corporation-the supreme court of Pennsylvania said: 'The remaining question is, What is the proper measure of the plaintiff's damages? His damages should equal the loss which the deceit which the jury have found was practised upon him inflicted. The loss, in the transaction before us, is the difference between the real value of the stock at the time of the sale and the fictitious value at which the buyer was induced to purchase. ”
