A group of stocks known as the "Parabolic 7", which includes Micron, SanDisk, and Marvell, has seen a significant decline as a trade unwinds. This development may be related to a shift in investor interest away from another group of stocks, sometimes referred to as the "Magnificent 7", and towards the "Parabolic 7" or possibly a new group called the "MANGOS". The impact of this shift on the broader market is unclear, with some outlets suggesting a rally in certain sectors and others warning of potential dangers.
