Consider Apple's meteoric rise in market capitalization. In February 2018, Apple became the first publicly traded company to cross the $1 trillion mark. This significant milestone not only highlighted Apple's financial strength but also had a profound impact on the stock market.

The surge in Apple's market cap led to increased confidence in the technology sector, spurring investments in other tech stocks.
