The markets haven't found their footing yet, Jim Cramer reluctantly told his Mad Money viewers Monday, after another very weak day on Wall Street. That means selling into any strength and continuing to nibble at the cheapest of stocks as they head still lower.

Cramer returned to his "Market Bottom Checklist," which he debuted in January, to see if investors have anything positive to look forward to. He said the Federal Reserve remains in a pickle because employment remains strong, but there are no other signs our economy is overheating. More clarity from the Fed will be needed to check off this market worry.

As for the political uncertainty, there's still no clarity on who the candidates will be or what their agendas might hold for the markets. There's also no resolution in the Chinese markets, but renewed tensions with North Korea after a missile test over the weekend.

Commodities and oil both continue to try to find a bottom, Cramer said, but aren't there yet. Likewise with the mergers and IPO markets, which have all but disappeared.

The U.S. dollar was the only bright spot on Cramer's list, as its strength is weakening, at least against the euro.

Finally, Cramer added a new box to the list, credit issues, which seem to be mounting for some European banks, added to existing fears of another credit crunch.

Cramer on LinkedIn

What should investors make of the carnage in LinkedIn (LNKD) and Tableau Software (DATA) , which plunged 44% and 49%, respectively, on Friday? Cramer donned his crime scene investigation gear to determine the true cause of death.

Cramer said that LinkedIn was once a high-flying growth stock, beloved for its mobile, social and cloud aspects. But that all ended Friday when the company reported in-line earnings but slashed its guidance citing global economic concerns. That lead to the stock losing $11 billion of market cap in the blink of an eye.

The cause of death? Everyone assumed that LinkedIn was a secular grower and immune to global worries. Turns out it's not, and that means many investors need to reevaluate. Cramer said this stock cannot be touched until the company's credibility is restored, which will take at least another three months.

As for Tableau, this data analytics company was eerily similar, delivering OK earnings with weak guidance. That lead to shares getting cut in half on Friday and losing another 10% today. Tableau cited increased competition and customers becoming more cautious, two things you don't want to hear from a growth stock.

Cramer said the problem with Tableau is that even down here, the stock still trades at 53 times earnings, just below (CRM) at 55 times earnings. Salesforce is growing like a weed. Tableau stock, Cramer concluded, cannot be touched.
