Shares of Facebook, as of Monday's $141 close, slumped 23.8 percent since mid-March when the Cambridge Analytica scandal came to light. The embattled social media giant was down fractionally on Tuesday.
"I think Facebook, which is an unmitigated disaster, is bottoming," Cramer said on "Squawk on the Street." His charitable trust, which still owns Facebook shares, has trimmed its position in recent months.
Facebook shares closed March 16 at about $185, a day before news broke of Cambridge Analytica's data misuse. Ten days after that, Facebook hit a then-intraday low of around $149, which represented a 19 percent decline.
Under scrutiny over data privacy from Washington and Wall Street, Facebook clawed its way to an all-time high during the July 25 trading of over $218 per share. But since then, Facebook lost 35 percent as of Monday, firmly in a bear market as defined by an asset or index decline of 20 percent or more from recent highs.
Facebook's 52-week low on Wall Street was $126.85 on Nov. 20.
For months, Cramer has been critical of Facebook and most recently its Chief Operating Officer Sheryl Sandberg, who was reportedly blamed by Facebook co-founder, chairman and CEO Mark Zuckerberg for the company's problems.
About two weeks ago, Cramer said Facebook's stock could rise if Sandberg were to resign or be ousted. Then on Friday, a day after an expose by The New York Times, the "Mad Money" host questioned how Sandberg could possibly stay.
