Stock (also capital stock) is all of the shares into which ownership of a corporation is divided. In American English, the shares are collectively known as "stock". A single share of the stock represents fractional ownership of the corporation in proportion to the total number of shares.

A house is a single-unit residential building, which may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers.
