Tech Five: Apple kicks off big earnings week

The tech earnings marathon continues, with several big names including Apple and Alibaba poised to report quarterly results this week.

Let's take a look at tech stocks to watch Monday:

Apple. The tech giant reports fourth quarter earnings when the markets close Tuesday, and the big question is how popular have the iPhone 6S and 6S Plus smartphones been with consumers. Analysts project Apple will report revenue topping $51 billion, with earnings of $1.88 a share. Apple launched its latest iPhones last month.

Twitter. Jack Dorsey prepares for his first earnings call as new CEO when the company reports third quarter earnings Tuesday. Analysts project earnings per share of 5 cents off revenue of $559 million. Dorsey has made several big moves since taking over the CEO role, including scheduling Twitter's first layoffs and rolling out the social network's new Moments feature.

Alibaba. The Chinese commerce titan might provide a forecast for the November 11 shopping holiday in China when it reports results Tuesday before the bell. Alibaba is forecast to report revenue of $21.32 billion with earnings of $3.45 a share. Last week, Alibaba announced it acquired remaining shares in Chinese video service Youku Tudou.

LinkedIn. The social network for professionals reports third quarter earnings Thursday. Analysts estimate earnings of 46 cents a share off $756 million in revenue. After hitting a 52-week high topping $270 in February, LinkedIn shares have sunk 22%.

Sony. The company is reportedly working on a deal to acquire Toshiba's image sensor business for $165 million, reports Bloomberg. A deal could be announced as early as this week.
