Linde is a buy in Cramer's lightning round.

• Jim Cramer is once again answering callers' stock questions at a rapid pace, as indicated by the ringing of the lightning round bell on "Mad Money."

If you understand the company, insiders who were buying the stock probably feel like, "Let's take matters into our own hands and buy the stock." I think it's a very inexpensive stock. It's the kind of stock that can work.

I am not comfortable with what they own because it makes me suspicious. I haven't opened what they've got, and I can't tell, so I'll say no.

Although the dividend is quite substantial, it is noteworthy that the rest of the cohort is significantly slower. However, I am highly fond of BHP and believe it is a wise investment.

I was upset that Linde's stock was down so much despite the company's unbelievable quarter and strong business. I agree with you that it's a buy.

I believe we need to wait and see a better quarter. The last quarter did not meet my expectations, leaving me feeling unimpressed and wondering, 'Is that all you can do?' Let's wait.
