Corner Tee

(FINANCE) Used either as a noun: a situation in which a trader controls the supply of a traded item, such as shares of stock, supplies of a commodity, etc. Or else, used as a verb: to obtain control over the supply of a thing, so that one can drive the price up to extremely high levels. Cornering the market for anything (or getting a corner) is extremely difficult and requires not only immense amounts of money (usually borrowed for the purpose), but also timing and the ability to bluff opponents. A corner is ultimately a long position in the sense that it is a direct attack on investors taking a short position.
