After another brutal session on Wednesday, Jim Cramer reminded investors that stocks still have the ability to go up. It's just that in this kind of a difficult environment, the key is to remain selective of the stocks owned.

That is why all week Cramer has been examining the best winners of 2015. He covered the Dow and S&P 500 and has now turned his attention to Nasdaq. The top five performers were Netflix, Amazon, Activision Blizzard, NVIDIA and Ctrip.com International.

However, there was another group of stocks within Nasdaq that were more interesting to Cramer. That was the next seven names beyond the top five. These names included Starbucks, Incyte Corp, Alphabet, Electronic Arts, Ulta Salon, T-Mobile and Expedia.

"Talk about a cluster of greatness!" the "Mad Money" host said.

Cramer's top pick was Starbucks, which has taken China by storm. He considers it to be the best single play on the middle-classification of the People's Republic.

But the most important thing about Starbucks' stock is that Cramer doesn't think it is done roaring. In fact, it might still be early.

"I can't tell you how many times I have heard that we don't need any more Starbucks or there are too many of them or that the world is already saturated. These statements come from uninformed people who simply don't understand that the main problem Starbucks has is that it doesn't have enough stores to meet all of the demand it stimulates worldwide," Cramer said.

Alphabet was another Cramer-fave winner, and is the cheapest of the FANG group. FANG is the cohort created by Cramer which represents Facebook, Amazon, Netflix and Google-parent Alphabet. Cramer estimated that Alphabet could earn $40 a share next year, and given its insane growth rate he thinks it is still a bargain at its current rate of 25 times earnings.

"Of these seven Nasdaq winners from 2015, I think Starbucks, Incyte, Alphabet, Ulta, Expedia and T-Mobile can keep going higher. Can they put up 40 percent gains like last year? I doubt it. We might not have that kind of year," Cramer said.

Cramer does think these stocks will do better than most other stocks this year, which is what makes them the cluster of greatness.
