US Stock Market Move | "Sell America" trading strategy reboots, with the Nasdaq falling nearly 1%, as most tech stocks decline.

On Monday, the three major US stock indexes collectively opened lower, with the Nasdaq falling nearly 1%. Most tech stocks were trading lower, with Tesla, Inc. (TSLA.US) dropping nearly 4%, Apple Inc. (AAPL.US) down nearly 3%, NVIDIA Corporation (NVDA.US), Amazon.com, Inc. (AMZN.US), and Alphabet Inc. Class C (GOOGL.US) all falling close to 1%. In terms of news, last week, credit rating agency Moody's Corporation downgraded the US credit rating from the highest level of Aaa to Aa1, and revised the rating outlook from "negative" to "stable". Moody's Corporation explicitly stated that the deteriorating fiscal deficit and political polarization in the US are weakening the credit foundation of the world's largest economy. Wall Street traders are restarting their "sell US" trading strategy. Scott Thiel, a strategist at BlackRock Investment Institute, said, "The market is reassessing the issue of long-term debt sustainability in the US, and this warning from Moody's Corporation cannot be easily dismissed."
