After President Trump on Thursday announced tariffs on $50 billion worth of Chinese goods, the market took a tumble, Jim Cramer told his Mad Money viewers Friday. That makes next week's game plan more important than ever.

Cramer said investors need to be prepared for more market gyrations on Monday, based on any reactions from China on trade. We'll also likely hear more about the Qualcomm (QCOM) bid for NXP Semiconductor (NXPI) , which may be a positive for the market if the deal is approved.

Tuesday brings earnings from FedEx (FDX) , a stock which Cramer said is too low, and Oracle (ORCL) , a stock that's been tricky, but could move higher with any earnings momentum.

Next, on Wednesday, it's earnings from Winnebago (WGO) and Micron Technologies (MU) . Cramer said Winnebago could head lower if inventories are high, as they were with Thor Industries (THO) , but Micron should deliver solid results.

Then on Thursday, it's Darden Restaurants (DRI) , an Action Alerts PLUS holding, in the spotlight, along with Kroger (KR) and RedHat (RHT) . Cramer said he's still a fan of Darden, but noted he doesn't expect good things from Kroger. RedHat will likely report good earnings, he said, but will likely see shares fall anyway. That's a good time to buy.

Finally, on Friday, OPEC will be meeting to decide the future of oil prices.

Cramer and the AAP team want to capitalize on the recent strength in Darden Restaurants (DRI) , and cash in a portion of those shares. Find out what they're telling their investment club members and get in on the conversation with a free trial subscription to Action Alerts PLUS.

Executive Decision: Manitowoc

In his first "Executive Decision" segment, Cramer sat down with Barry Pennypacker, president and CEO of Manitowoc (MTW) , to discuss trade, tariffs and the company's outlook. Shares of Manitowoc are off 35% for the year.

Pennypacker said he's not too worried about tariffs. He said President Trump campaigned on tariffs and as soon as he took office, Manitowoc began taking actions to minimize their exposure. What's important, he said, is that with a booming economy, cranes are everywhere.

Pennypacker highlighted his company's self-erecting cranes as a big growth driver, as are the resurgence of the oil and gas industry and the expansion of wind energy -- all of which need more cranes. For some models, Manitowoc is sold out through 2019.

Manitowoc has also been aggressively paying down debts, Pennypacker added, all while continuing to focus on their corporate culture of making Manitowoc the best it can be every day.

Cramer says when you spend a whole day interviewing and listening to more than a dozen people, as he did last week at TheDeal's Corporate Governance conference, you can come back with a gazillion ideas. Check out his Top Takeaways over on Real Money.

Subscribing to the Subscription Economy 

Don't let trade wars blind you to all those companies that are immune to tariffs, Cramer told viewers. As we learned on Thursday night's show, the subscription economy is for real.

Cramer said there were many takeaways from last night's interview with Tien Tzuo, founder and CEO of Zuora (ZUO)  , not the least of which is that subscriptions aren't just for music and DVDs. The end of ownership as we know it, many be coming to an end.

Indeed, subscriptions aren't just for Netflix (NFLX) . Apple (AAPL) now has a $30 billion services business that is only beginning to gain momentum. Meanwhile, Amazon's (AMZN) Prime membership now extends to foods, merchandise and more. Costco (COST) has 90 million annual members.

Subscriptions aren't just about money, it also drives loyalty. Adobe Systems (ADBE) is another terrific of example of subscriptions at work, as is The New York Times (NYT) .

Executive Decision: Centene 

In his second "Executive Decision" segment, Cramer spoke again with Michael Meidorff, chairman and CEO of Centene (CNC) , on the heels of the company's annual analyst day. Shares of the healthcare provider are up 22% in 2018.

Meidorff said he's very excited about his company's merger with Fidelis, which received approval today from the New York State Attorney General. He said the deal will make Centene the largest provider in the four largest insurance states and it will allow Fidelis to do a better job managing their patients.

Meidorff added that Centene is a technology company that provides healthcare. The company has technology that helps identify patients that may be at risk for opioid addiction and has been able to lower addiction by 20% over the past 12 months.

Cramer said that Centene is not done heading higher.

No-Huddle Offense: Banks

In his "No Huddle Offense" segment, Cramer opined on why the bank stocks have been underperforming, even though they should be rallying from rising interest rates.

Conventional wisdom says the yield curve is too flat for banks to make any money, while others posit that mortgage loans are slowing. But Cramer said he's not buying either these theories and fears that banks may have a bigger problem looming.

There is a change, he said, that younger money managers just aren't that into the traditional financial sector, preferring more hip online alternatives, like Paypal (PYPL) and Square (SQ) . Still others firmly believe, rightly or wrongly, that bitcoin and other cryptocurrencies can unseat the old-line banks. For many millennials, banking is done on their phone, but not at a bank, which could eventually spell trouble. Cramer said he banks need to see some real earnings momentum before investors begin to take them seriously again. 

Lightning Round

In the Lightning Round, Cramer was bullish on Okta (OKTA) and Home Depot (HD) .

Cramer was bearish on Celgene (CELG) , GasLog Partners (GLOP) , Neutral Tandem (TNDM) , Altria (MO) , Axovant Sciences (AXON) and Lowe's (LOW) .
