Stocks were mostly lower on Monday after a terror attack in London over the weekend, a slump in crude oil, and a rare analyst downgrade on Apple (AAPL) shares. 

The S&P 500 was down 0.02%, the Dow Jones Industrial Average was flat, and the Nasdaq increased 0.03%.

Still, stocks held close to records with market reaction to terrorism appearing restrained and cautious. Wall Street largely overlooked weaker-than-expected U.S. jobs growth in May on Friday, with major benchmark indexes closing at records for the second day in a row.

"There is little market reaction to another terrorism event in London, and oil is barely budging on a political spat in the Middle East," said James "Rev Shark" Deporre in his daily column over on our premium site for investors, Real Money.

Seven people have died and 50 more have been injured in a terrorist attack near the busy London Bridge Station in the center of the British capital late Saturday, Metropolitan Police have confirmed. Police said three men drove a white transit van at high speed toward London Bridge just after 10 p.m. local time, deliberately targeting pedestrians before continuing to the busy restaurant and pub district of Borough Market, which was packed with revelers enjoying the unusually warm summer Saturday evening.

"Enough is enough," U.K. Prime Minister Theresa May said in a statement. "There is far too much tolerance of extremism in our country ... we cannot and must not pretend that things can continue as they are." May said the general election would take place as scheduled on June 8, though campaigning was suspended for the day. 

President Donald Trump reacted to the terror attack by criticizing London Mayor Sadiq Khan and railing against "political correctness." In a series of tweets, Trump said, "We need to be smart, vigilant and tough. We need the courts to give us back our rights. We need the Travel Ban as an extra level of safety!" The White House had previously asked for Trump's twice-blocked travel "ban" to be reviewed by the Supreme Court. 

Apple fell Monday after a rare downgrade for the world's biggest tech company by Pacific Crest Securities, which advised clients to buy shares in Google owner Alphabet ( GOOGL) instead. Pacific Securities analyst Andy Hargreaves said that while Apple "anticipates strong performance in the iPhone 8 cycle" it has given "relatively little weight to risks through the cycle or the potential for iPhone sales to decline" in fiscal 2019. Pacific Crest also noted that "recent supply checks suggest iPhone 8 (OLED) may be delayed until October with limited initial supply that ramps through" to the first quarter of Apple's fiscal 2019, which begins on Oct. 1.

Hargreaves reduced his view on Apple to sector weight, from a previous rating of overweight, and thinks the stock could fall by $10 over the next year. Apple shares close Friday at $155.45.

TheStreet's Jim Cramer noted the unusual downgrade on his Twitter account early Monday, and in particular questioned the timing of the move, which comes just ahead of Apple's Worldwide Developers Conference, which begins Monday.

Services activity in the U.S. expanded at a slower-than-expected pace in May, according to the Institute for Supply Management. The ISM non-manufacturing index came in at 56.9 in May, down from 57.5 previously. Analysts anticipated a reading of 57. 

U.S. factory orders declined as expected in April. The Census Bureau reported a 0.2% decline in orders over April, in-line with consensus, after a 1% increase in March. 

First-quarter productivity in the U.S. was left unchanged, while unit labor costs weakened from a previous estimate. U.S. productivity over the first three months of the year was down 0.6%, while output was increased to 1.7% from a previous 1% estimate. Hours worked increased to 1.7% from 1.6%, while unit labor costs fell to 2.2% growth from 3%. 

Four countries -- Saudi Arabia, the United Arab Emirates, Bahrain and Egypt -- have cut diplomatic ties with Qatar over its ties with terrorism. The move escalates a rumbling dispute between Qatar, its sometime partner Iran, and their regional neighbors. Tensions between the country could erode cooperation among the Organization of Petroleum Exporting Countries. OPEC recently agreed to extend their output cut agreement by nine months to address a global supply imbalance. 

West Texas Intermediate crude oil gave up earlier gains to fall 0.8% to $47.29 a barrel on Monday. 

Time Warner (TWX) shares rose after its film Wonder Woman topped the domestic box office over the weekend. The DC comic book film earned $100.5 million in its debut weekend, the best opening in the U.S. for a female-directed movie. 

Herbalife (HLF) was lower after increasing its current-quarter adjusted profit guidance, but lowering sales forecasts. The company anticipates earnings between 95 cents and $1.15 a share over its current quarter, up from a previous target of 88 cents to $1.08 a share. However, sales are expected to come in 1.5% below previous estimates. Herbalife cited the transition to the new FTC rules in the U.S. along with softness in its Mexico business as reason for lower-than-anticipated revenue. 

Forestar (FOR)  jumped 13% in after homebuilder D.R. Horton (DHI) proposed to purchase a 75% stake in the company for $520 million, or $16.25 a share. The purchase price represents a 14% stake over an existing merger agreement between Forestar and investment firm Starwood Capital Group

Tempur Sealy (TPX)  fell despite reporting a positive sales update for the first two months of its second quarter. Excluding Mattress Firm, orders across all brands over the first two months of the quarter increased 7%. North America sales increased 15% in May, driven by a 28% surge in orders for Tempur-Pedic products. 

Gap (GPS)  fell slightly after a ratings upgrade. Oppenheimer analysts increased their rating to outperform from perform and raised their price target to $28 from $24.

WebMd (WBMD) rose on Monday on reports IAC (IAC) was interested in an acquisition. IAC is reportedly considering purchasing the medical search engine for $61 a share, a roughly 7% premium to its trading levels on Friday. 

Gigamon (GIMO) surged 12% on reports the network software developer is seeking discussions with possible buyers. Elliott Management has been pushing for the company to consider a sale after it acquired a 15.3% stake in the company in May.
