Not only did Klarna file for IPO today, but the company also inked a deal with Walmart (WMT) to become the retail giant's buy now, pay later provider. Caroline Woods notes Klarna's gain is Affirm's (AFRM) loss, as the company sold off after the announcement. Alan Knuckman later joins and offers an example options trade for Walmart. He highlights the company's slashed stock premium and its rebound as a buying opportunity.
