JPMorgan, Wall Street's largest bank, has warned that it expects further short-term weakness in stock markets due to geopolitical tensions. The warning came in a note to clients, Mislav Matejka, head of global equity strategy, warned that geopolitical tensions could continue to drive a wave of risk reduction across markets. The bank expects the current episode of market stress to last days or weeks, not months, and is urging clients to watch for oversold conditions and stretched positioning to clear. Once that happens, JPMorgan sees the selloff as a buying opportunity. The firm also highlighted specific pockets of the market it expects to benefit once the current wave of selling clears and positioning resets.
