Take a look at some of Friday's midday movers:
Tableau Software soared after its IPO. The data software company sold 8.2 million shares at $31 per share raising $254 million.
Visa hit a historic high after a Nomura analyst said the global payments firm justified a P/E multiple of 25-times earnings and raised his price target on the firm to $220 from $187 per share.
Aruba Networks plunged after the tech company reported fiscal third-quarter earnings and revenues that missed expectations. The network equipment maker also forecast fourth-quarter earnings below consensus on increased competition from Cisco. A slew of analyst downgrades and lowered price targets followed Aruba's quarterly results and outlook.
Newmont Mining hit another 52-week low as the price of gold continued to slide.

Pandora traded lower after MKM Partners initiated the stock with a "sell" rating, with a price target of $10 per share.
Northrop Grumman, Master Card and Johnson & Johnson were among companies that hit historic highs. Meanwhile, Ford, Halliburton and Boeing hit new 52-week highs.
