Original title: us stock technology sector rose sharply during the year, while memory chip stocks became an "alien" source: British Financial Information Investing.co

Yingwei Investing.com-US technology stocks have risen sharply this year, but memory chip and memory hardware makers have not been able to "party together".

Western Digital, which makes hard drives and NAND chips, has lost nearly 1/3 of its market value this year, while rival NASDAQ:STX is down 19 per cent. Micron Technology Inc, the largest US memory chipmaker, fell 7 per cent. Over the same period, the Nasdaq index is up 16% and the Philadelphia semiconductor index is up 11%. Karl Ackerman, an analyst at Cowen, said the poor performance of these stocks was largely due to investor concerns that memory demand from cloud, corporate and PC customers would fall in the coming quarters, leading to a glut in the market and falling prices. However, Ackerman expects the balance of demand to remain good in the second half of the year, especially for NAND memory; these manufacturers are also likely to report better-than-expected quarterly results. Seagate will report quarterly results on July 28, followed by Western Digital on Aug. 5.
