Did you miss last night's "Mad Money" on CNBC? If so, here are some of Jim Cramer's top takeaways.

After spending years in the doghouse, shares of FMC Corp (FMC - Get Report) have finally reignited, and Cramer said he'd be a buyer on any weakness.

For those not familiar with FMC, the company is largely a manufacturer of agricultural chemicals, which account for 70% of sales. But FMC also makes compounds for lithium batteries, a business that is now growing at 22% a year.

Cramer said that when agriculture was out of favor, FMC continued to invest in itself and make smart acquisitions, most of which are only now bearing fruit.

On the company's conference call in early November, FMC noted strength in Latin America, particularly Brazil, as well as in Asia and North America. Goldman Sachs (GS - Get Report) added the company to its Conviction Buy list on Dec 12.

After falling from a high of about $84 a share to as low as $32 a share, Cramer said, FMC is inexpensive where it's trading now, at $58 a share and 18 times earnings -- especially after bullish comments from rival Monsanto (MON) today.

Cramer said you probably want to buy stocks that Trump slams on Twitter.
