This creative brief outlines a music video reimagining "All I Want for Christmas Is You" with a financial twist. The video features a cartoonish Warren Buffett joyfully singing and dancing at a New Year's party in a classic American mansion. The goal is to blend holiday cheer with playful commentary on the stock market. The style combines colorful sketch animation with a retro holiday aesthetic. The tone should be lighthearted and celebratory, capturing the excitement of both the season and market gains. Background details like a Christmas tree, fireplace, and reindeer decorations enhance the festive mood. This concept aims to entertain finance-savvy viewers while maintaining broad appeal through its whimsical approach and familiar holiday setting. The video should convey optimism about the market's future in a fun, accessible way.
