CNBC's Jim Cramer on Wednesday said his favorite stock market indicator is showing that it's time to buy stocks despite bearish signs from the bond market. The "Mad Money" host also explained why he has soured on sector ETFs. Later in the show Cramer spoke with Barrick Gold CEO Mark Bristow about managing business during a disease outbreak.   

CNBC's said Wednesday it's time to buy stocks despite the bearish signal emanating from U.S. Treasurys as coronavirus fears persist. 

The "Mad Money" host said pointed to a trusted market indicator as evidence for his bullish call: the MarketEdge Short Range Oscillator. 

"I expect a mild recession based on weakness in travel and entertainment, but right now the oscillator is saying you should buy stocks, both short and long term," Cramer said. 

Barrick Gold CEO Mark Bristow said it's possible for companies to operate during disease outbreaks if proper precautions are taken. 

Barrick's operations were located within close proximity of the 2014 outbreak of Ebola in West Africa, Bristow said on "Mad Money." 

"You can manage this," Bristow said, emphasizing the importance of keeping track of who enters a company's operations. 

Cramer said the recent market volatility should serve as the beginning of the end for sector ETFs. 

"I know I'm early, but anyone who doesn't see this index fund peak on the horizon is fooling themselves," Cramer said. 

"Why own both the winners and losers in an industry when you can just pick the very obvious winners?" Cramer added. 

Luckin Coffee: "Well you're rolling the dice with Luckin. We got a lot of dice rollers. I don't mind that at all because in the end you're allowed to speculate. But do think that if you like a coffee company, you ought to buy the one that my charitable trust has been buying, and that would be Starbucks." 

American Tower Corp.: "American Tower is good ... Yes, I know about the combination between T-Mobile and Sprint. I don't care. We still need more towers and that's going to be great for American Tower." 

JD.com: "No. Don't. Look, we've got the Alibaba. How much do we have to be in there? No."
