Stock market live Tuesday: Dow surges 500, JPM jumps on Dimon comment, China worries ruin the close

Stocks started the holiday-shortened week on a high note, building on recent strength. All major averages are coming off a positive week — the Dow's best since early April — as investors have cheered economies reopening, as well as a potential Covid-19 vaccine. The S&P 500 jumped past 3,000 during Tuesday's session but failed to close above the threshold after concerns about U.S.-China tensions intensified again. Here's what happened:

• The Dow gained 530 points, 2.17%, breaking a two-day losing streak. 
• The Dow hit its highest level since March 6 in Tuesday's session.
• The Dow is up 2.67% month to date, on pace for its second positive month in a row. 
• Dow impact: Goldman Sachs had the most positive impact on the Dow, adding 111 points to the index.   
• The S&P 500 gained 36 points, 1.23%, its third positive session in four. 
• The S&P hit its highest level since March 5 in Tuesday's session. 
•  The S&P is up 2.72% month to date, on pace for its second positive month in a row.     
• SPY impact: JPMorgan had the most positive impact on the SPY, adding 0.26 points to the ETF.
• The Nasdaq Composite gained 16 points, 0.17%, its third positive session in four. 
• The Nasdaq is up 5.07% month to date, on pace for its second positive month in a row.   
• The Russell 2000 gained 2.77%, its fourth positive session in a row and seventh positive session in eight.

• Nine of 11 S&P Sectors were positive in Tuesday's session, led by financials, which went up 5.04%.  Health care was the worst performer, down 0.19%.   — Hayes

The market registered solid gains on Tuesday on hopes of a successful economic reopening and a potential coronavirus vaccine. The Dow Jones Industrial Average jumped more than 500 points, closing points below the 25,000 threshold. The 30-stock benchmark had crossed 25,000 during Tuesday's session. The S&P 500 rose 1.1% to close around 2,991, after spending most of the day above the psychological 3,000 level. The Nasdaq Composite rose just 0.2%.— Li

The Trump administration is eyeing sanctions on Chinese officials, businesses and financial institutions over China's move to crack down on Hong Kong, Bloomberg News reported Tuesday afternoon, citing people familiar with the matter. The potential actions could include freezing assets of Chinese officials and companies for implementing a national security law that will bypass the legislature in Hong Kong, Bloomberg News said, adding no decisions has been made yet. Stocks pared gains following the news in the final minutes of trading on Tuesday. --Li 

The major averages were on pace to notch sharp gains with one hour left of trading amid optimism around the U.S. economy reopening along with mounting bets on a potential coronavirus vaccine. The Dow and S&P 500 traded at levels not seen since March, surging 2.7% and 1.8%, respectively. The Nasdaq Composite lagged with a 0.8% climb. —Imbert

The iShares MSCI Brazil ETF (EWZ) rallied more than 8% on Tuesday after data released by the country's central bank showed a record current account surplus for April. Tuesday's rally would be the ETF's biggest since March 24, when it popped over 12%. To be sure, the EWZ is still down more than 40% year to date as Latin America's biggest economy gets battered by the coronavirus pandemic. —Imbert, Francolla

Citigroup's widely followed investor sentiment model is showing optimism at its highest level in a year. The firm's strategists think that could be a mistake. The Panic/Euphoria model is registering much more of the latter after a two-month stock market rally off the March lows. As is common with sentiment indicators, they mostly work as contrarian signs. The indicator reached a "panic" low that coincided almost perfectly with the plunge to the March 23 bottom and was a great opportunity to buy. But the present "euphoria" level could be an opposite indicator. "We worry that investors are almost setting themselves up for a correction since there are too many unpredictable factors in play and thus the downside potential is not being priced correctly," Citigroup Chief Equity Strategist Tobias Kevkovich said in a note. One danger point is when corporate officers a month from now start releasing their second-half outlooks, particularly if they say the rebound from the sharp coronavirus-induced downturn won't be as sharp as stocks are indicating. "Chasing the market currently is a tad risky but we would be more intrigued with buying at lower levels," Levkovich said last week. The firm has a 2,700 year-end price target for the S&P 500, pointing to an 8.6% downturn from Friday's close. –Cox

With just a few trading days left in May, the month is shaping up to be a relatively calm one for stocks by recent standards. The range this month for the Dow has been roughly 2,400 points. This compares with 4,029 points in April, and 8,888 and 4,887 points in March and February, respectively. By historical standards, however, May's 2,400-point move would be considered exceptional. In January, for instance, before Covid-19 lockdowns halted economies worldwide, the Dow traveled 1,204 points. –Hum, Stevens

JPMorgan Chase CEO Jamie Dimon said his company is "very valuable" at current stock price levels, sending the bank's shares to their session highs. Dimon made his comment while responding to a question about JPMorgan's valuation. Investors pay close attention when Dimon speaks about his bank's valuation or makes changes to his JPMorgan holdings. In 2016, Dimon bought $26 million worth of JPMorgan shares at a time that proved close to the market bottom back then. "I'm not going to try to predict the bottom," Dimon said, adding that "you cannot be a bank and be immune to what goes on in the world out there."— Imbert, Son

Stocks could finish the year higher even after the market's massive drop earlier in 2020, if history is any indication. Oppenheimer's John Stoltzfus pointed out that, "even as drawdowns of 7% or more have occurred in 19 of the [past] 22 years, the S&P 500 has experienced a negative annual return in only six of those years."

New York Stock Exchange President Stacey Cunningham said on "Squawk on the Street" that she does not expect the protections put in place for workers at the exchange to prevent all infections.

In response to whether the floor of the NYSE would close again if a worker tested positive, Cunningham said the measures — which include temperature checks and mandatory mask-wearing — were designed to prevent outbreaks.

"It's not designed to prevent an individual case. Somebody may be exposed outside of this building, show up here and we find out that they tested positive. The protections that we put in place have been designed to prevent an outbreak so that the likelihood of an infection passing around the floor is greatly diminished," Cunningham said. —Pound

Department store chain Macy's said in a memo for its new bond offering that it is seeing a stronger rebound in customers at its reopened stores than it had been anticipating. Macy's reopened 68 stores on May 4 and is gradually opening others.

"We have seen greater demand than we expected, with demand averaging approximately 50% compared to 2019 levels.

Canaccord strategist Tony Dwyer expects a "relative bounce" in "value, banks and tanks (industrials)" as the economy continues to reopen. "The SPX has seen a historic move on the back of the mega-cap 'COVID-19' beneficiaries of the shelter-in-place policy for most of the country," Dwyer wrote in a note. "As the economy accelerates the reopening and the financial conditions reverse their recent tightening, there is likely to be a shift into those areas that benefit from a broader and more vibrant recovery." —Imbert, Bloom

Wall Street latched onto more positive news Tuesday on the coronavirus front, with progress made both on the reopening of several states and progress made towards a vaccine.
