Charles Schwab's Joe Mazzola says there's a lot to take away from today's trading session. For one, he's "impressed" with the way dip-buyers lifted stocks off session-lows despite the developing tariff headlines. Joe discusses why yields may not have gained as much traction as others expected. Heading into the long weekend, he urges investors to keep an eye on institutional hedging and economic data as signals to be aware of next week.
