2019 was seen to have significant impacts for the leading tech giants and have also seen their market caps grow rapidly. Meanwhile, tech companies annihilated the country's biggest pharmaceutical, chemical, and consumer good companies in terms of profit, growth and influence.

According to an analysis from CNBC, if the S&P index exceeds 500 at the end of the year that means that there will be best returns in the next six years. Meanwhile, if it passes 31 percent this means that there will be best returns in a period of 22 years. 

However, 2019 is a boon and a bane for some companies. There are companies who gained returns and there are also some who lost revenue due to some external factors. 

According to Forbes here are the companies that saw cap gain in 2019:

1. Apple

Apple is the leading company this year that increased its market value. It rose by $497 billion to nearly $1.25 trillion and its stocks hit the new record high in the second half of this year. Apple benefited a lot from its product sales and its venture into the streaming wars.

2. Google

Google is still the leading search engine in the world and it attracts more digital advertising. It also expanded its business into artificial intelligence or A.I. and self-driving cars. Its market value has increased by $214 billion to almost $934 billion.

3. Facebook

Facebook has continued to dominate as the leading social media platform in the world. This led them also to attract more digital paid advertisements and more revenue by adding more new users. It has gained its market value by $213 billion to $587 billion before this year ends.

4. Amazon

Amazon is the leading online retail store. Before 2019 ends, it increases its market value to $887 billion. Its revenue is coming from its product sales and advertising businesses. 

There are also other financial services companies that made it have their market value increase this year. That includes Visa with a $115 billion, JPMorgan Chase with $111 billion, and Mastercard with $106 billion. 

However, despite the market gains of these companies especially the leading tech giants, it is inevitable that there are also companies who lost revenues this year. Here are some of the companies that suffered losses:

1. DuPont

DuPont was previously known as the leading, and world's largest, chemical conglomerate. Its market value has fallen nearly $37 billion this year and an estimated $47.5 billion before this year ends. 

2. Pfizer

Pfizer merged with the Upjohn generic drugs division earlier this year. However, the merger was seen to have negative impacts. Its market value fell by $33 billion to $218 billion before the year end.

3. Kraft Heinz

One of the investors in this company is the billionaire Warren Buffet where he holds 27 percent of the stake. In February this year, its stock fell to 30 percent due to the decrease of the market value of its leading brands, Kraft and Oscar Mayer, by more than $15 billion. The company did not recover before this year end and its market value lost $13.5 billion.

4. Walgreens Boots Alliance

This international drug store faced a big challenge this year due to competition from online retailers. This led the company to slash the costs and somehow explore a massive leveraged buyout from a private company. Their market cap has decreased from $13.1 billion to $52 billion before the year end.

5. Occidental Petroleum

Its market cap falls into $11.5 billion before this year ends. Wall Street investors also worry about its debt load that is estimated to be around $37 billion.
