Trade is an all-encompassing term that refers to every profession, trade, business, employment, calling, occupation or venture, including the letting of any property, and the use of any patent, design, trademark, copyright, or any other similar property.
'Trade' implies an active occupation, as opposed to the passive earning of investment income.
Certain activities, such as investments in dividend-bearing and interest-bearing stock, are not included in the definition of trade.
