So what

Despite last month's stock drops, October saw Pure Storage continue to form new partnerships and secure new contracts. The company published a press release on Oct. 9 detailing its new partnership with data protection provider Veritas Technologies. The team-up will see the two companies integrating their respective services in order to make sharing, backing up, and analyzing large amounts of data easier.

Pure Storage also posted some encouraging news on the service-expansion front last month. The company published a press release on Oct. 12 revealing that it had secured statewide contracts in North Carolina and New York, and then published a press release on Oct. 16 stating that Salinas Valley Memorial Healthcare had implemented the business' storage infrastructure and quickly seen operational improvements.

Now what

In spite of some recovery earlier in the month, Pure Storage stock has lost additional ground in November. Shares are down roughly 4.6% through the month's trading so far.^SPX Chart
