Tech stocks are enduring a significant selloff, sparking questions about whether the bubble is finally bursting. The downturn comes without the usual geopolitical catalysts, as oil markets stabilize amid a messy Middle East compromise taking shape.

Micron Technology Inc. may provide the next catalyst, with the $1.2 trillion company poised to release results that could shake markets further. Beyond that, there's little fresh news to explain the broad-based tech decline.

Author John Authers suggests this likely isn't the definitive bubble-bursting moment. However, the selloff highlights how much over-leveraged damage could still unfold in a sector that has driven market gains for months.

The episode serves as a reminder that tech valuations remain stretched, and even without a clear catalyst, investor nerves can trigger sharp repricing. The damage so far appears contained, but leverage amplifies any downward moves.
