GLNDW

GLNDW is a warrant tied to Greenland Energy Company, which SEC records classify under oil and gas well drilling services. A warrant is not a share of stock itself, it's a contract that gives the holder the right to buy shares of the company at a fixed price before a set expiration date. Its price rises and falls based on how the underlying stock performs relative to that fixed buying price, which is why warrants swing much harder than the stock they're attached to.
