U.S. semiconductor stocks have been hit hard in the past month following President Donald Trump's administration's blacklisting of Huawei, which has raised the specter of wider restrictions to Chinese firms' access to American technology. Semiconductors are one of America's biggest tech exports and China is a crucial market because of the amount of electronics manufacturers relying on U.S. chips. Trump signed an executive order last month that gave permission to Commerce Secretary Wilbur Ross to block transactions that involve information or communications technology that "poses an unacceptable risk" to U.S. national security. Huawei was then put on a blacklist that requires American firms to get permission to sell to the Chinese networking equipment and smartphone giant. The move has hit the businesses and share prices of U.S. chip firms.

A number of exchange-traded funds (ETFs) that track semiconductors have performed worse than the Nasdaq Composite in the past month. The Direxion Semiconductor Bull 3X Shares ETF, which counts Qualcomm and Texas Instruments as its top individual stock holdings, is down more than 34% in the last month. The ProShares Ultra Semiconductors, which has Intel as its top holding, is down nearly 25%. Other ETFs that track semiconductors are also lower. In comparison, the Nasdaq Composite is down 7.4% in the last month.
