"So, you know, we're earning 25 percent more on the S&P than we did two years ago on just three percent revenue growth, which is fantastic. It's the kind of earnings leverage you only see in an early part of a recovery. And it's happening in a turbocharged fashion now. So we still like equities. We think we'll see some chop in August, but the earnings power really wins the day."
