There's never really a dull moment in the tech sector as innovation keeps something or other brewing. Making this sector even more exciting are the mega trends such as mobile, cloud computing, cyber security and Big Data analytics, with extensive applications that are more of a necessity for consumers today.

Take, for instance, cloud computing. According to Centaur Partners, Software-as-a-Service (SaaS) and cloud-based business applications are likely to grow from $13.5 billion in 2013 to $32.8 billion in 2016, reflecting a compounded annual growth rate (CAGR) of 19.5%. Moreover, Computerworld forecasts that 42% of IT decision makers are planning to increase spending on cloud computing in 2015.

A recent IDC forecast claims that another major trend Big Data technology and services market will grow at a 26.4% CAGR to $41.5 billion through 2018, or about six times the growth rate of the overall IT market.

Tech Bubble? Nah!

Job growth is humming — jobless claims fell to its lowest since 1973 and innovation is all around. The excitement around this sector — thanks to the surprisingly stronger-than-expected results from three tech titans — Alphabet (GOOGL - Analyst Report), Amazon (AMZN - Analyst Report) and Microsoft (MSFT - Analyst Report) last week — might remind you of the period before the tech bubble. But we do not believe it will burst this time.

Why?

This time the companies have been around for a longer time and recorded more profits than they did back then. Investors and analysts seemed to have learnt their lessons and are not blindly investing in any tech company.

Tech Love

It’s time to show the tech sector some love as these trends are here to stay.

Following August’s market rout and another slump in September, stocks staged a dramatic comeback in October. Stocks bounced back following the no-rate hike decision by the Fed. Additionally, investors have realized that the soft revenues were the result of a strong dollar.

Add to this the unexpected rate cut in China and the possibility of more stimuli for Europe, and you will believe that the overall market is not that bad and that tech is the hero right now.
