The markets have a long checklist to cross off before mounting a true comeback, CNBC's Jim Cramer said Monday.
Insider selling needs to slow down, the IPO market needs to cool off and the formerly high-flying momentum stocks such as 3-D printing company Stratasys need to stabilize, Cramer said on "Squawk on the Street." That's a lot of hurdles in a week that could see big moves in the market, he said.
Coming off the worst week in the S&P 500 and tech-heavy Nasdaq since June 2012, the markets have plenty of headline-grabbing events to digest this week. Fifty companies in the S&P report earnings, and Cramer said one in particular ought to give investors a good measure of how the tech sector should fare: Google.
The company reports earnings Wednesday.
"Google will be the proxy on whether this group will do well," Cramer said. "Don't go crazy until you see the whites of their eyes, [until] you see some of these earnings reports."

Gauging the stock market's general well-being, however, is more difficult, Cramer said. Tensions between Ukraine and Russia heated up over the weekend, and a lackluster earnings report from JPMorgan spurred a deep selloff on Friday.
On Monday's open, a better-than-expected earnings report from Citigroup sent stocks higher. Cramer said investors need to take this week one headline at a time.
"I don't ever want to say its OK, knowing that you have landmines like we had last week with JPMorgan and Wells Fargo, [and] that the coast is clear," Cramer said. "This is ... case-by-case."
