JPMorgan’s tone has been shifting by the day. Last Monday, JPMorgan strategist Mislav Matejka wrote that the “current geopolitical escalation should ultimately be an opportunity to add, as fundamentals are positive,” and said investors with a longer horizon should be “using the weakness to add into.” A week later, Matejka’s tone had darkened: “Things might need to get worse before they can get better,” he wrote, even as he argued that the selloff may still have a “relatively limited lifespan” measured in “days/weeks, rather than months/quarters.”
