An exchange traded fund tracking Nasdaq stocks fell below its 200-day moving average in Wednesday’s sell-off in another sign of a potential technical breakdown in stocks.

PowerShares QQQ (NasdaqGM: QQQ) was down about 2% in afternoon trading Wednesday as the Dow dropped almost 200 points. Investors were unnerved by protests in Greece and Europe’s debt crisis.

Key Nasdaq-100 components and tech captains Apple (NasdaqGS: AAPL) and Microsoft (NasdaqGS: MSFT) also slipped about 2%.

Traders will be looking for any follow-through to the downside now that the ETF has breached the technical indictor.

The Nasdaq-100 fund came into Wednesday’s session with a year-to-date gain of 1.8%, according to Morningstar.

“Is this the big fear spike we needed to finally flush weak holders, or the start of a new bear market?” said on Wednesday. “So many technicians now follow the 200-day, it will be most curious indeed.”
