Nasdaq 100 Falls 5.5% in Worst Week in 18 Months Amid Broader Market Correction

The Nasdaq 100 dropped 5.5% in its worst weekly performance in 18 months, triggering broader risk-off sentiment across equities and crypto markets.

  • The Nasdaq 100 index experienced a sharp 5.5% decline over the course of the week, marking its worst performance in a year and a half.
  • Heavy losses in major technology heavyweights weighed heavily on market sentiment, spilling over into risk assets including cryptocurrencies.
  • Traders and macro analysts are closely monitoring macroeconomic indicators and upcoming central bank commentary for signs of prolonged volatility.

The Nasdaq 100 index suffered a dramatic contraction, dropping 5.5% in what financial market analysts confirmed as its worst weekly performance in 18 months, as reported by Reuters. The steep sell-off was driven primarily by a broad correction across mega-cap technology shares, which have faced mounting pressure amid shifting macroeconomic expectations and elevated interest rate concerns.

This sharp downward correction in traditional equities quickly reverberated through digital asset markets. Bitcoin and major altcoins experienced synchronized pullbacks as institutional investors reduced exposure to high-beta risk assets. Market participants noted that correlation between tech equities and crypto assets remains pronounced during periods of heightened macro uncertainty, amplifying liquidations across derivatives platforms.

According to market data providers cited by Bloomberg, the tech-heavy index faced relentless selling pressure from the opening bell on Monday through Friday’s close. Traders are now adjusting their portfolios to account for potential prolonged volatility as upcoming economic data releases loom large. Risk management desks advise caution as liquidity thins out across both traditional stock exchanges and digital asset order books.
