After several tries, Amazon has officially joined the elite trillion-dollar club on Tuesday, when the company's shares soared 2.5 percent to end at $1.021 trillion in market value, FactSet reported.

The e-commerce titan has reached $1 trillion early Monday and just a few days before that, but fell short in keeping its valuation through the final bell.

Amazon also briefly hit the $1 trillion mark during intraday sessions last July and September 2018, but came up short each time. Market capitalizations are only accepted as official at the close of the day's trade.

The company's latest entry into the $1 trillion level was a result of solid profits in the fourth quarter as posted on Thursday's after-hours sessions.

Amazon disclosed record holiday season profits than estimated despite its huge spending on dividing delivery times for Prime subscribers.

Amazon becomes only the fourth American stock to end with this valuation, next to Apple, Microsoft and Alphabet, the new member of the superclub for the first time in January.

Alphabet officially settled with a market cap of around $993 billion late Tuesday after a dismal profits report dragged its shares down 2.6 percent.

Saudi Arabia's state energy conglomerate, Saudi Aramco, currently holds the record for having the biggest market value with $1.8 trillion.

Amazon's latest feat also further boosts the fortune of its top boss, Jeff Bezos, who owns almost 12 percent of outstanding Amazon stocks, Bloomberg data showed. Bezos, ranked by Forbes as the wealthiest person in the world, has a net value of around $124 billion.

Tech's most influential brands have breached the so-called four-comma organization, despite the Department of Justice and Federal Trade Commission's probe into their business practices and market clout. In addition to Amazon, Apple and Alphabet, social media giant Facebook is also being investigated.

So, experts say, stock valuations are likely to increase. Wedbush Securities market planner Daniel Ives predicted last week that so-called FAANG companies will lead stocks in the industry up another 25 percent this year. Elsewhere, Gene Munster, a former Apple analyst, claims Apple will hit $2 trillion in the next 10 years.

Meanwhile, Bezos unloaded over $1.8 billion of shares in his company during the past week, according to the company's financial filings.

Approved under the board's pre-arranged trading deal, the series of sales commenced Jan. 31 and continued through February 3. The filings also disclosed that Bezos has sold more than 905,456 shares valued at $1.84 billion all in all.
