The S&P 500 rose Monday to notch its best day since June 5 as tech shares bounced on the heels of the worst weekly loss for the index since April.

The benchmark climbed 1.08% to settle at 5,564.41 and clinch its best day since June 5, while the Nasdaq Composite advanced 1.58% to close at 18,007.57. The Dow Jones Industrial Average rose 127.91 points, or 0.32%, to finish at 40,415.44.

Nvidia popped 4.8%, recovering some of its 8% pullback from last week. Other major tech stocks such as Meta Platforms and Alphabet also rose more than 2%. CrowdStrike was the worst performer in the S&P 500, dropping 13.5% and building on last week's nearly 18% loss.

"We're seeing a rotation back into the technology sector after a pretty meaningful sell-off, exacerbated by the CrowdStrike meltdown," said Mona Mahajan, a senior investment strategist at Edward Jones. "A combination of broadening in earnings and the Fed cutting rates is giving investors some hope."

Tech stocks were under pressure last week as investors rotated out of those names in favor of smaller names, sending the S&P 500 lower by nearly 2% last week. The Nasdaq shed more than 3% during that period.

Despite tech's strong gains, small-cap stocks held up. The Russell 2000 closed about 1.7% higher on Monday.

Traders also kept an eye on the U.S. political landscape after President Joe Biden dropped out of the presidential race on Sunday and endorsed Vice President Kamala Harris. Since Biden's disastrous debate performance in June, many analysts were seeing an increasing likelihood of a win by former President Donald Trump in November.

Earnings and central bank policy remain top of mind for Wall Street. Traders have been pricing in a nearly 93% likelihood of the Federal Reserve cutting interest rates during its September meeting.

Correction: The Russell 2000 gained 6% in the week ending July 12. An earlier version misstated the timing.

Advisors were more bullish than their clients earlier this year, State Street says

Investors who listened to their financial advisors earlier this year may be breathing a big sigh of relief.

Financial advisors were more bullish about the stock market than their clients early in the second quarter, according to the 2024 ETF Impact Survey from State Street Global Advisors.

"US financial advisors are much more optimistic about the global economy than investors. 68% are optimistic about the global economic outlook — significantly higher than advised investors at 28%," the survey said.

The survey was conducted in April, and the individual investors included had at least $250,000 in investable assets.

CNBC Pro: Biden dropping out adds more uncertainty to markets. What investors are saying

President Biden dropping out of the election has removed a key overhang from the election. Since his disastrous performance in the June debate, many analysts were anticipating a higher likelihood of a Trump victory in November.

Now, Wall Street is deliberating the U.S. political outlook as Biden's endorsement of Harris has muddied expectations for who will win the election, and has added uncertainty to markets.

"We will continue to have both bulls and bears because you have both sides who are talking about the uncertainty, increased uncertainty regarding the presidency," said Sam Stovall, chief investment strategist at CFRA Research.

Inflation can 'fall like a rock,' Tom Lee says

Friday's inflation data in the personal consumption expenditures price index should show cooling, according to Tom Lee, head of research at Fundstrat Global Advisors.

"One print can be uncertain, but I think the forces underway for inflation to fall like a rock are in place," Lee said on CNBC's "Squawk on the Street."

Lee said there does not appear to be any new drivers of inflation, which means it could surprise to the downside. He also said there is "urgency" for the Federal Reserve to begin cutting interest rates.

Crypto stocks gain while bitcoin hovers at the flat line

Bitcoin was little changed on Monday, a day after President Joe Biden dropped out of the presidential race and endorsed Vice President Kamala Harris.

"The markets dipped shortly after Biden announced he would drop out because there is no immediate successor named, in terms of a presumptive nominee, and uncertainty fuels doubt," said Bartosz Lipiński, CEO at crypto trading platform Cube.Exchange. "Once Kamala was endorsed by him and others, the markets largely recovered and appear to be taking the news somewhat well despite remaining mostly flat today."

Bitcoin was last lower by less than 1% at $67,257.88, according to Coin Metrics. However, Coinbase rose 2%, while mining stocks Riot Platforms and Iris Energy gained more than 1% each.

AMC Entertainment restructures debt, pushing out maturities to 2029 and beyond

Shares of AMC Entertainment popped 8% Monday following a brief halt to allow the movie theater chain to share news that it bought itself a little more time with creditors by restructuring debt.

The multifaceted deal pushes out the maturities of as much as $2.45 billion in debt, originally due in 2026, to 2029 and 2030, the company said. As part of the refinancing, a separate unit of the company has been created that will own the leases and property of 175 theaters and other assets, including the AMC brand name, according to a filing with the U.S. Securities and Exchange Commission.

Even before the Covid-19 pandemic shuttered movie theaters for months and dried up revenue, AMC was laden with debt. Since then, the company has looked for creative ways, including taking advantage of a temporary boost in its stock price during the "meme stock" craze, to deleverage its balance sheet.

Equities have a 'cushion' to digest political uncertainty, Strategas' Dan Clifton says

The past couple of weeks have been rife with political uncertainty, from former President Donald Trump's convictions and attempted assassination to incumbent President Joe Biden dropping out of the race.

Still, even in these unprecedented times, Strategas head of Washington policy research Dan Clifton noted that the S&P 500 has rallied 6% over the past seven weeks.

"There are limits to how much the political events are going to have impacts on the broader equity market," he said on CNBC's "The Exchange," pointing to liquidity increases provided by the U.S. Treasury as the reason. "So there's a cushion to digest some of this political uncertainty."

Berkshire resumes selling down winning BYD bet

Berkshire Hathaway resumed selling down its stake in BYD, now owning less than 5% of China's biggest electric vehicle maker.

Warren Buffett's conglomerate has trimmed its lucrative BYD stake to 4.94% as of July 16, according to a filing to the Hong Kong Stock Exchange. 

The "Oracle of Omaha" credited his late business partner Charlie Munger for convincing him — a famous hater of technology businesses — to invest in Shenzhen-based BYD, which has turned out to be one of Berkshire's most profitable.

Hong Kong's rules only require a filing when a stake percentage crosses a whole number, so if Berkshire's stake falls below 4%, there will be another filing.

Expect a 'reversal of the reversal,' says UBS

The broad rotation out of megacap tech stocks in favor of rate-sensitive sectors such as industrials, real estate and regional banks is a "stunning reversal across equity markets," says UBS head of asset allocation Jason Draho.

"The leaders in the first half of the year are the relative losers this month, while previous laggards have gone on a tear," Draho wrote in a Monday note.

The S&P 500 is higher by just 0.8% month to date, while regional banks and the Russell 2000 are up 14.5% and 7.6%, respectively.

However, Draho believes the previous market rally leaders will soon resume their winning position.

"The overall evidence leans in favor of … a reversal of the reversal," Draho said.

Draho noted that ideal macro conditions must be maintained for the rate-sensitive sectors to continue outperforming.

However, "there is a fine line between good macro data and ideal conditions necessary for the rotation trade to be sustained. In particular, investors may be getting ahead of themselves in expecting Fed rate cuts," said Draho.

Rotation away from Big Tech has room to run, Deutsche Bank says

The rotation away from Big Tech and into small caps that happened last week will be more than a short-term blip, according to Deutsche Bank.

Strategist Parag Thatte said in a note to clients over the weekend that the market is still pricing in too much optimism about the growth areas of the market that have led most of the bull rally.

"While overall equity positioning remains elevated there have been sharp rotations in positioning and flows away from [megacap growth] & Tech and into other sectors and small caps, and in our view, these have plenty of legs to run medium term. MCG & Tech positioning is still aligned with a continuation of extremely strong earnings growth and upgrades while we see a slowing as growth catches back down to the trend rate in place for the last 2 decades," the note said.
