With jobless claims at 6 year lows, you wouldn't think the market would sell-off. But it did and Cramer thinks you need to heed the message.
"You'd think that kind of macro input – the Thursday jobless claims number – would be terrific news," said Cramer.
And it is good news, for the economy. But when the Street gets that kind of strength immediately interest rates go higher. And in this market environment that's bad.
It calls the housing recovery into question; also, it triggers speculation that the Fed will begin tapering sooner rather than later. That's not only bad for stocks, it's bad for bonds too. "Plenty of people think that's the case, so they are dumping their bonds betting the Fed's done buying them," Cramer said.
As a result, bond prices dropped and yields spiked. "The key ten-year U.S. government Treasury, the bellwether bond, shot up to 2.76% and the 30 year bond flew up to 3.8%," Cramer said.
Those so-called 'negative inputs' are enough to send stocks tumbling, alone. But on Thursday other negative inputs surfaced, too.

Over the past 24 hours, two companies stunned the Street; Cisco and Wal-Mart.
"They did more than stun," said Cramer. "They totally befuddled and ultimately jolted the market." Cisco gave a weak outlook and announced a big layoff while Wal-Mart said that shoppers made fewer trips to its stores, likely feeling the pinch from higher payroll taxes and gas prices.
