An asset sale is the purchase of individual assets and liabilities, whereas a stock sale is the purchase of the owner's shares of a corporation. Asset Sale lets buyers choose specific assets and liabilities; Stock Sale doesn't.While an asset sale outshines a stock sale in company structure support, it loses a fair amount of points when it comes to tax implications. In stock sales, the buyer purchases the owner's shares of the corporation. Unlike asset sales, stock sales do not require conveyances of each individual asset. A stock sale is one that involves the sale of a business's outstanding shares of stock.
