According to Peter Tuchman, markets managed to climb the wall of worry on news of the U.S. and China tariff pause. "Not getting a deal is so bad that we have to get a deal," says Peter, adding that optimism on a deal gave investors a signal the worst may be over. On UnitedHealth's (UNH) CEO stepping down and its lack of guidance, Peter says it presents a growth pressure scenario that can resurface. Keeping uncertainty low is what Peter believes will drive markets higher.
