NEW YORK (TheStreet) -- Jim Cramer answered viewers' Twitter (TWTR - Get Report) questions on the floor of the New York Stock Exchange and addressed Caterpillar's (CAT - Get Report) announcement that it has lowered its revenue outlook and plans to cut 10,000 jobs.

"These numbers were chilling," said Cramer. "I think people are going to say the dividend is in jeopardy."

Cramer said Caterpillar is adjusting to the new reality. "Their oil business is going down and their coal business is going down, and those are two very key markets," said Cramer.

Cramer was also asked if it's time to buy United Technologies (UTX - Get Report) , and he said no. He pointed out that his Action Alerts PLUS portfolio holds Honeywell (HON - Get Report) and 3M (MMM - Get Report) , both of which are doing better than United Technologies, but he noted that neither of those stocks can find their footing. Cramer said he's still not buying any more shares of those companies, even after their recent declines.

Another viewer asked what Cramer expects from Apple (AAPL - Get Report) heading into the holiday shopping season. Cramer said Apple has a lot of new products, like Apple Watch, that will generate recurring revenue. He also likes the fact that Apple is moving forward with an electric car.

He said Apple's a stock to hold, and if it gets back to a range of $92 to $95, it's a buy.

Cramer was also asked whether Visa (V - Get Report) is a good domestic play irrespective of interest rates. He responded that it's an international play -- and the company is doing marvelously.

"I think Visa is a terrific company, and will be a great stock as it comes down," said Cramer, who also noted that MasterCard (MA - Get Report) is doing well. Cramer added he likes Paypal (PYPL - Get Report) because it's the least expensive and has the fastest growth.

Finally, Cramer was asked about Swift Transportation (SWFT) . Cramer said XPO Logistics' (XPO - Get Report) recent deal to buy Con-way (CNW) makes the transports sector look interesting, but he prefers buying UPS (UPS - Get Report) in the low $90s.
