Cramer Remix: This is your chance to buy Amazon, not sell it · CNBC

President Donald Trump 's bold and unpredictable leadership style tends to spark volatility in the stock market, prompting many investors to ask Jim Cramer if it is time to shift retirement investments to cash .

"My answer is no and yes," the " Mad Money " host said.

Yet that doesn't mean investors should go into cash and dump their stock exposure in their 401(k) and IRA plans, Cramer said. If you are on the verge of needing that money, then he blessed taking some out.

As for a stock investment, a low cost S&P 500 (^GSPC) Index fund is something that could be considered for the long-term.

"You can still pick stocks, but they have to be part of a broader theme, a theme solid enough that it can trump, well, Trump," Cramer said. "Otherwise you will just jettison the stock when the 'Tweeter in Chief' frightens you into selling, at what will no doubt be an inopportune time."

For investors that believe in the social, mobile, cloud and artificial intelligence cohorts, Cramer recommended Alphabet (GOOGL), Amazon (AMZN) and Facebook (FB). Amazon's stock fell 4 percent after-hours on Thursday because of a lighter than expected forecast.

"These are your chances to get in, not get out and don't be deterred with Facebook just because SNAP filed to go public tonight and its growth looks solid," Cramer said.

Facebook (FB) has perhaps the best business model of all time , according to Cramer.

"When you have an amazing product that is beloved and in demand worldwide and it costs very little to produce and has no serious competition. That's Facebook," he said.

Thus, Cramer was shocked when investors sold the stock of Facebook on Thursday. He considers the social network to be a very rare company with incredible prospects, with a fairly low stock valuation compared to most other stocks.

"There aren't many of those and as it goes down over the next couple of days, which has been the pattern, I think you would be nuts to pass it up," Cramer said.

Shares of International Paper (IP) fell 5 percent on Thursday after the company reported earnings, which CEO Mark Sutton attributed to a " margins squeeze " that occurred in the second half of 2016.

"We had input costs rising. We were able to raise prices, but that's just beginning to take traction as we turn the calendar into 2017," Sutton told " Mad Money " host Jim Cramer.

International Paper is the top maker of corrugated packaging in North America, and a major producer of coated paperboard and un-coated free sheet. The stock has had a big run since the election, up to nearly $58 last week from $44 on Election Day.
