Mad Money W/ Jim Cramer

The Dow closed up 92 points and Cramer’s digging into another record day. Then, after a powerful post-earnings move, Cramer’s checking in with the CEO of Dexcom to make sense of the stock’s recent strength. And, just ahead of the new year, Cramer’s pinning two fitness stocks against each other, Planet Fitness vs. Peloton, to see which stock could keep your portfolio in shape. And, the mall and lodging REIT’s have felt the pain recently. Cramer’s sitting down with Hersha Hospitality’s CEO to see if this high-end hotel real estate investment trust is ready to rise above the pack.
