Apple's (AAPL) brief brush with $5 trillion in market capitalization on Tuesday marked a historic milestone that immediately raises the question of whether the stock can sustain these elevated levels or is due for a pullback.
AAPL reached an intraday high of $342.89, pushing its valuation to roughly $5.036 trillion before settling back to close at $340.08, making it only the second company after Nvidia (NVDA) to achieve this milestone.
