The 'Magnificent 7' tech stocks retreated on Thursday, with Tesla (TSLA) and Apple (AAPL) leading the decline. The group had rallied just a day earlier, buoyed by Tesla's 8% surge after CEO Elon Musk teased the company's AI5 chip. However, investor enthusiasm waned as Bernstein analysts projected a staggering $5 trillion to $13 trillion capital expenditure for the project, raising concerns about its financial viability.

Apple faces heightened scrutiny ahead of its earnings report, with analysts bullish on strong iPhone demand and growing services revenue. Yet margin pressures and the looming question of its next major product cycle weigh on sentiment. The broader tech sector remains sensitive to geopolitical tensions, as Middle East hostilities continue to cast a shadow over market momentum.
