$NFLX U.S. margin debt, or what investors borrow from their brokerages to buy securities, rose 54% to a record
$1.4 trillion in May from a year earlier, according to Finra data. Meanwhile, high-risk leveraged exchange-traded funds that produce double or triple the daily move of underlying stocks are growing rapidly, as is trading in options tied to them. Most include A.I. stocks and at some point in time things are not going to end well. NFLX might be a safe heaven.
