Ahead of Friday's closing bell, Kevin Hincks reports from the Cboe Global Markets to offer a wide perspective on this week's overall down action. He attributes much of the selling to macro uncertainty and high valuations in high-flying tech stocks. As for the government shutdown, Kevin notes airlines across the industry like American (AAL) and United (UAL) cancelling flights due to short staff. He later tackles headlines on Tesla (TSLA) after shareholders voted for CEO Elon Musk's $1 trillion pay package.
