markets through the lens of ETFs. ETFs

are a great measurement of investor

day, an ETF will do about 30% of volume.

>> Say that again.

>> ETFs will do about 30% of US exchange

volume on a given [clears throat] day.

stocks and ETFs is basically the

summation of all the all the trading

volume. On a daily basis, ETFs are 30%

of the total.

>> Yes. And stocks are the remaining 70%.

>> growing.

And then during more stressful

environment, when everyone's freaking

out, they'll go up to 40 to 45% cuz

people are adjusting exposures.

>> So, they're this great tool.

>> They're selling tech and they're buying

staples, whatever.

>> they're doing. Could be used for

hedging, shorting, whatever it might be.

they can There's 5,000 of them, right?

How can we

>> ETFs.

>> 5,000 ETFs. How many stocks are there?
