Evidently, "Russell 1000: The 1,000 largest public U.S. companies. The Russell 1000 and Russell 2000 are collectively known as the Russell 3000, which is regarded as one of the best barometers for the overall U.S. stock market's performance."
So maybe we were listed on the Russell 2000 on June 4th, and hope to move to the Russell 1000 by June 28th. I reckon that might take some revenue to show that kind of growth. Just guessing, though.
