September 17 Cometh
Citing respected chartist Larry Williams, Cramer told TheStreet Live Monday that, historically, September 17 typically marks the beginning of a downturn and one of the toughest periods for investors.
So is it time to build up your cash reserve? In his latest column on Real Money, Cramer had a few words of wisdom for investors.
"I have said over and over again that September is the cruelest month and it's playing out that way with rolling corrections all over the place. What goes up today will go down tomorrow and vice- versa. That's a recipe to lose money. Better just to keep some cash, own some gold and wait, unless you are a trader and if that's the case, heed the Williams warning and do some selling today tomorrow and Thursday, if only just to get ahead of all of those who don't know that Sept. 17 starts the toughest period of the year," Cramer wrote.

Apple's annual 'California Streaming' hardware event is expected to kick off at 1 p.m. ET. Among numerous product reveals, industry watchers widely expect to see a first look at new iPhones, AirPods and Apple Watches.
Ahead of the event, Apple updated its iOS operating system after Israeli cyber surveillance unveiled a method to hack into iPhones without any user interaction.

Don't Let the IPO Eat Your Homework
On CNBC's 'Mad Money,' Cramer took the examples of Clear Secure (YOU) , Blade Air Blade Air and Wheels Up to explain the importance of doing your homework well before investing in the latest round of public offerings.
While Blade Air and Wheels Up make attractive speculative plays, Cramer said Clear Secure's valuation makes the stock far too risky. Clear Secure is valued at 25 times sales.
Eyes on the Cloud
