My biggest concern for this market remains that we get an unexpected economic slowdown

“My biggest concern for this market remains that we get an unexpected economic slowdown because that’s one of the few events that can legitimately cause a material correction in stocks,” writes Sevens Report founder Tom Essaye, noting that his worry ticked up last week due to corporate earnings.

However, Essaye warns, it doesn’t always work so neatly. “Twice in my career I have seen investors cheer a slowdown, and both times the Fed was not able to cut rates at the right time to prevent the slowing from becoming a broader economic contraction,” he wrote. “That doesn’t mean they can’t do it this time, but catching a falling knife doesn’t work in real life, it doesn’t work in stock trading, and I’ve never seen it work in monetary policy.”
