The business world is certainly not a static one.

In the past, we’ve shown that the market leaders in the most stable industries are unlikely to keep their leadership positions over long periods of time.

But limit your window to just the dynamic world of tech and you’ll see an even more extreme example of this inherent volatility. Sometimes companies are able to separate from the rest of the pack for days or months, but it’s never an advantage that lasts for long.

Biggest Tech Companies by Market Cap

Today’s animation was originally posted to Reddit by /r/TheNerdistRedditor and captures the crazy world of tech valuations for public companies.

Watch the intense 1 minute animation below:

Note: the data here only lists companies traded on U.S. exchanges, and does not show every single valuation point.

Over just 23 years, the company topping the list flips eight separate times – and if you were to get more granular with the numbers (looking at daily valuations, for example), you’d see it happen far more often.

Today’s Market Cap Leaders

As we noted above, company valuations are constantly changing – and back in early September 2018, both Apple and Amazon even topped the $1 trillion milestone for a short period of time.

Using the same criteria as the above animation, which is based on U.S. listed companies, here are the top 10 tech companies based on data at time of publication:

This is not a comprehensive list globally, as it misses companies like Tencent which are listed on other exchanges such as the Hong Kong Stock Exchange. Based on recent HKD/USD conversion rates, it’s estimated that Tencent would be roughly worth $450 billion today – good enough for 7th on the list.

Regardless, since change is the only constant in the tech world, it’s fair to say that the above list of the biggest tech companies will likely be much different in just a few months time.

The Economies Adding the Most to Global Growth in 2019

Global economics is effectively a numbers game.

As long as the data adds up to economic expansion on a worldwide level, it’s easy to keep the status quo rolling. Companies can shift resources to the growing segments, and investors can put capital where it can go to work.

At the end of the day, growth cures everything – it’s only when it dries up that things get hairy.

Breaking Down Global Growth in 2019

Today’s chart uses data from Standard Chartered and the IMF to break down where economic growth is happening in 2019 using purchasing power parity (PPP) terms. Further, it also compares the share of the global GDP pie taken by key countries and regions over time.

Let’s start by looking at where global growth is forecasted to occur in 2019:

The data here mimics some of the previous estimates we’ve seen from Standard Chartered, such as this chart which projects the largest economies in 2030.

Asia as a whole will account for 63% of all global GDP growth (PPP) this year, with the lion’s share going to China. Countries like India and Indonesia will contribute to the “Other Asia” share, and Japan will only contribute 1% to the global growth total.

In terms of developed economies, the U.S. will lead the pack (11%) in contributing to global growth. Europe will add 8% between its various sub-regions, and Canada will add 1%.

Share of Global Economy Over Time

Based on the above projections, we were interested in taking a look at how each region or country’s share of global GDP (PPP) has changed over recent decades.

This time, we used IMF projections from its data mapper tool to loosely approximate the regions above, though there are some minor differences in how the data is organized.

In the past 40 years or so, Developing Asia has increased its share of the global economy (in PPP terms) from 8.9% to an estimated 34.1% today. This dominant region includes China, India, and other fast-growing economies.

The European Union and the United States combined for 51.5% of global productivity in 1980, but they now account for 31% of the total economic mix. Similarly, the Latin America and MENA regions are seeing similar decreases in their share of the economic pie.
