2. -- Cisco Returns to Revenue Growth

Shares of Cisco rose 7.9% in premarket trading on Thursday after the networking giant's fiscal second-quarter earnings topped forecasts and its top-line grew.

"In Q2, we returned to revenue growth," Chairman CEO Chuck Robbins told investors in a call after the market close on Wednesday. 

Cisco's revenue, which had declined for eight consecutive quarters according to FactSet, rose 3% in the quarter to $11.9 billion, beating a consensus forecast of $11.8 billion. Adjusted earnings of 63 cents a share topped expectations of 59 cents. 

Among other positive notes in the quarter was that Cisco's Catalyst 9000 router was catching on with buyers.

"The Catalyst 9000 is the fastest ramping product in our history," Robbins told investors, noting that its count of 3,100 customers doubled over the prior year.

3. -- Buffett Likes Apple ... a Lot

Warren Buffett's Berkshire Hathaway inc.  (BRK.A)  lifted its stake in Apple Inc. (AAPL) by a whopping 23% since the end of September to 165.3 million shares, according to a new filing.

Buffett has shown a voracious appetite to eat up Apple, likely as the company gets ready to spend enormously on dividends and buybacks amid tax reform. 

Berkshire's Apple stake is worth about $28 billion, just above the reported $27.8 billion stake in Wells Fargo & Co. (WFC) , according to Reuters.

Berkshire acquired its first stake in Apple in May 2016. At the time, the conglomerate said it purchased 9.8 million shares at an average price of about $109 a share.
 
Apple closed Wednesday at $167.37, up 1.8%. Shares rose 1.2% in premarket trading to $169.40.
