Robinhood said Wednesday it resolved an issue that showed users incorrect portfolio balances. The discount brokerage told multiple customers in afternoon tweets that it "encountered an issue on May 27th that may have caused your app to temporarily display an incorrect portfolio value." "We've since resolved this, so the portfolio value you see now is accurate," the company added. Various users tweeted complaints throughout the day saying their account values were moving out-of-step with underlying investments. One said their portfolio funds and profits were "fluctuating when I do not even own anything." (full story)
