Here are five things you must know for Wednesday, Oct. 2: 

1. -- Stock Futures Fall as Grim Manufacturing Data Rattles Wall Street

U.S. stock futures pointed lower on Wednesday following the biggest single-day decline on Wall Street in more than a month after a grim reading of factory activity in the U.S., the world's biggest economy, sparked concerns for a global recession led by the trade spat between Washington and Beijing.

The Institute for Supply Management's manufacturing index in September fell to its lowest level since 2009, with export orders tumbling amid the protracted trade dispute and employment contracting as plants and facilities idled and investment stalled. The data, which hammered U.S. stocks on Tuesday, followed the weakest reading for European manufacturing in seven years and ongoing signals of a sharp slowdown in both China and Japan.

Donald Trump used the data to rail yet again at the Federal Reserve, calling the central bank "pathetic" for not lowering interest rates further and thus inflating the value of the dollar. However, most analysts noted that trade uncertainty, not dollar strength, was the common theme among those polled by the closelyfollowed survey, suggesting deeper concerns for the global economy.

"This survey is a not consistent with recession across the whole economy, but the warning signs here are clear enough: The trade war is wreaking havoc, to the point where the incipient upturn in manufacturing in China is not transmitting, at all, to the U.S.," said Pantheon Economics' Ian Shepherdson. "This means that if consumers' confidence seriously falters, the U.S. could tip into the first recession ever caused directly by the actions of the president rather than the action of tight monetary policy on an overstretched private sector."

Contracts tied to the Dow Jones Industrial Average fell 158 points, futures for the S&P 500 were down 17.80 points, and Nasdaq futures declined 55.50 points.

The economic calendar in the U.S. Wednesday includes the ADP National Employment Report for September at 8:15 a.m. ET, and Oil Inventories for the week ended Sept. 27, at 10:30 a.m.

Homebuilder Lennar (LEN) - Get Report reported third-quarter earnings of $1.59 a share, beating Wall Street estimates of $1.32. Revenue in the period rose 3% to $5.9 billion. The stock rose 2.3% in premarket trading to $57.

2. -- Johnson & Johnson Settles Opioid Lawsuits in Ohio for $20.4 Million

Johnson & Johnson (JNJ) - Get Reportsettled opioid lawsuits with two Northeast Ohio counties for $20.4 million.

The company said the settlements with Cuyahoga and Summit counties remove it from a federal trial set to begin on Oct. 21

The settlements come a little more than a month after an Oklahoma judge ordered the healthcare giant to pay $572 million over its marketing of opioids in that state.

Johnson & Johnson and other opioid manufacturers still face some 2,000 other lawsuits related to the nation's opioids epidemic.

Privately held Purdue Pharma declared Chapter 11 bankruptcy in September under the weight of legal battles tied to its opioids business and after settlement talks with nearly two dozen state attorneys general collapsed.

Johnson & Johnson didn't admit liability in the settlements announced Tuesday. The company will pay a $10 million settlement, $5 million in legal fees, and will make a $5.4 million contribution to non-profit groups with opioid related programs in the two counties.

In a Twitter posting early Wednesday, Facebook's David Marcus said, "For Libra to succeed it needs committed members, and while I have no knowledge of specific organizations plans to not step up, commitment to the mission is more important than anything else."
