Strategist warns: Nasdaq's 8% rise in 20 minutes is not much healthier than an 8% fall

Odaily News Mark Hackett, chief market strategist at National Investment Management Group in Philadelphia: Trump's suspension of tariffs is definitely good news because it shows that the negotiations are in a good enough state that they think they have accomplished what they needed to accomplish through the initial dialogue. But I want to make a very important warning, because the Nasdaq index rising 8% in 20 minutes is not much healthier than falling 8%... So I am very careful now and can't give you a security alert.
