Apple chief executive Tim Cook has a trillion reasons to smile.

The tech titan on Thursday became the first company in the world to reach a $1 trillion valuation. It became the first $900 billion company exactly nine months ago, on Nov. 3, 2017.

The iPhone maker entered the rarefied air of a 13-digit market cap as its share price hit $207.05. It began an ascent Tuesday after reporting solid results in its latest quarter.

Apple sold 41.3 million iPhones last quarter, and reported an average selling price of $724.
