Four times a year, something extraordinary happens in the markets. Every publicly traded company in the U.S. — from megacap tech giants like Apple to tiny biotech firms you've never heard of like Zymeworks — are required by law to step into the spotlight and show their hand. They release their quarterly earnings reports. They tell us how much money they made, what’s working, what isn’t, and what they expect for the months ahead. And almost without fail, these announcements trigger the biggest stock moves of the year.
