CNBC's Jim Cramer on Tuesday warned investors about market froth and gave his take on the top 15 performers in the Russell 1000 during the month of July.
Froth can be a hard market condition to define, Cramer conceded.
Sometimes froth happens when the stock of a poorly-performing company spikes before the whole enterprise goes under, Cramer said.
To help investors spot market froth, Cramer discussed July's top 15 stocks in the Russell 1000, a benchmark index that ranks the top thousand companies in the U.S. by market capitalization.
"When you look at the biggest winners in the Russell 1000 last month, I'm very happy to say that the vast majority of these stocks, aside from QuantumScape and Robinhood, represent real substance, not just thin gruel froth," Cramer said.
