Stock market news live updates: Stocks extend gains, S&P 500 and Nasdaq set record highs

Stocks gained on Tuesday, reaching fresh all-time highs as optimism over earnings and the economic reopening at least temporarily outweighed lingering concerns over the virus and changes to monetary policy.

The S&P 500 edged up to fresh record intraday and closing highs. Big Tech stocks including (AMZN) added to gains, and the Nasdaq outperformed to also set new record levels. "Reopening" stocks including the airlines and cruise lines also increased after rising on Monday, with optimism over a broader leisure and travel recovery coming after the U.S. Food and Drug Administration granted full approval to Pfizer (PFE) and BioNTech's (BNTX) COVID-19 vaccine.

Shares of Chinese technology companies rose, shaking off the past several weeks' steep declines amid a regulatory crackdown of the major tech firms in China. The jump came after Ark Investment Management — run by the closely watched investor Cathie Woods — scooped up shares of Chinese e-commerce company JD.com (JD) following the firm's better-than-expected quarterly results. Peers including Alibaba (BABA) and Baidu (BIDU) also advanced, and the Hang Seng index (^HSI) increased by 2.5%.

Investors are also eagerly awaiting the Federal Reserve's virtual Jackson Hole Symposium beginning on Thursday. The event is expected to serve as another forum for central bank officials to discuss their assessment of economic conditions, and offer hints as to when the Fed might announce and eventually begin the process of tapering its crisis-era asset purchase program.

New economic data out at the start of the week disappointed relative to Wall Street's estimates, with an index tracking activity in the U.S. services sector cooling to an eight-month low as concerns over the Delta variant started to weigh on demand.

Despite the ongoing risks around the virus, however, three major factors have served to help keep equity markets marching toward fresh all-time highs, according to one strategist.

"The first one, that's extremely low discount rates. The 10-year Treasury yield is barely off the August lows," Michael Darda, MKM Partners chief economist, told Yahoo Finance. "So all things equal, if interest rates are low, if discount rates are low, valuations will tend to be higher because of a lack of competition."

"In addition to that, we have a very high liquidity environment ... and earnings have been incredibly strong," he added. "Typically when long-term interest rates are falling, earnings or the economy is faltering. In this case, the earnings have been quite robust, really historic. So we're really going to need to see one of those three pillars disturbed in some fashion for a big decline in equity prices."

Others offered a similarly upbeat take on the trajectory for U.S. equities.

"We think the primary trend is higher," Keith Lerner, Truist Wealth chief market strategist, told Yahoo Finance. "You're only about one year into this economic expansion. Economic expansions last about five years. And the earnings season which we just got out of was phenomenal once again."

"Even if it's peak growth, we still think it's going to be strong growth," he said. "You have earnings moving forward, and then you look at the relative comparison of stocks relative to bonds and they're still attractive ... Overall we think the right position is to be overweight stocks."

12:50 p.m. ET: Why cyclical sectors may still have room to run: Strategist

As markets jump to all-time highs, a rotation has been under way beneath the surface, with cyclical and growth stocks vying for leadership amid dual concerns over the pace of the economic recovery and path forward for monetary policy. According to at least one strategist, a move by the Federal Reserve away from its current ultra-accommodative policy tilt could be an incoming catalyst for another move higher in cyclical sectors.

"You really have to have your head on a swivel because for the first part of this year, owning interest rate-sensitive cyclical sectors, financials and others was a very good place to be," Andrew Ries, chief investment officer at 6 Meridian, told Yahoo Finance on Tuesday. "And then that turned over the summer."

"I think going forward, it's likely that the Fed makes it clear that rates at this level, or this level of accommodation, probably isn't necessary," he added. "I think you also have some issues with regards to ... what's going on in Congress with some of the stimulus packages, the infrastructure bill. So all of those are going to impact probably the trajectory of interest rates. And if rates move up ... moving up a little bit probably provides a tailwind for those cyclical sectors, the financial stocks, and probably a little bit of a headwind for the tech that's had the big run-up."

Shares of airlines including Southwest (LUV), United Airlines (UAL) and Delta (DAL) were each also higher on the day, boosted by optimism over the economic reopening following the full FDA approval of Pfizer and BioNTech's COVID-19 vaccine.
