Cramer recommends buying Rio Tinto.

We don't need to do that as HP Inc. already owns the 3D industry and will generate profits, so you should invest in HP Inc. Symbol HPQ.

The stock is still priced too high, and I want to emphasize that its inconsistent earnings are not suitable for us. We will look elsewhere.

I think you should stick with it because it reminds me of Renewable Energy, the company that recently received a bid from Chevron. I like that call.

No, no. We prefer the 'picks and shovels' approach to the pot industry, which is a challenging and risky business, similar to gambling. Therefore, I am not interested.

I'd rather see you in Lowe's. To me, it's a poor man's version. Lowe's had a great quarter.

I am a fan of Rio Tinto. [Buy, buy, buy]. Its minerals are highly valuable, and I am excited about the current bull market in minerals.
