TheStreet's Jim Cramer says momentum names like Workday, Splunk, and Salesforce.com will not bring down the market as a whole. Cramer says the last time a "cohort" this large took over the market was in March of 2000. But, Cramer believes that right now momentum names are not much of a factor. Looking back to the last bottom, Cramer says it was actually good for other areas of the market that started to outperform, like utilities, consumer packaged goods, and oil.
