Major stock indices rose today on optimism that, as certain states reopen, the economy will improve.

CNBC said the Dow Jones Industrial Average, as of 3:12 p.m., was up about 300 points, while the S&P 500 had gained 1.5 percent and the Nasdaq had climbed 1.9 percent.

As states began lifting lockdowns, previously battered stocks such as  MGM Resorts, United Airlines and Live Nation Entertainment were all up, as were retailers like Target, which reported higher earnings. Also bolstering markets were tech stocks such as Amazon and Facebook, both of which have climbed to an all-time high.

Bloomberg noted that stocks did trim a few of their gains on news of the Senate passing a bill that would subject Chinese firms to Public Company Accounting Oversight Board (PCAOB) inspection rules, but overall the market still remains about 30 percent higher than its March low. However, Bloomberg noted that, this month, the advance has been stop-and-go and seems to lack the force that the earlier rally possessed.
