Life has come full circle for tech stocks. After being the worst-performing S&P 500 Index ($SPX) subsector in 2022, tech is so far the best-performing sector this year. The steep rally in tech stocks led to a massive rally in the Nasdaq Composite ($NASX) in the first half of 2023, which was eventually its best start to the year in four decades.
Amid the rally, the combined market cap of Nasdaq constituents soared by a whopping $4 trillion in the first half of 2023. Several other milestones were reached this year, as well. While Apple (AAPL) became the first company ever to close at a market cap of over $3 trillion, Nvidia (NVDA) joined the ranks of trillion-dollar companies.
