iShares Russell 2000 ETF (IWM)

Tuesday’s session kept the recent repair phase alive and, in several areas, strengthened it. Breadth improved again, short-term participation stayed strong, and the major index ETFs pressed into important resistance zones.

Monday’s breadth data argues that Friday’s cooling phase was just a pause. Participation broadened sharply again, the major index ETFs extended their recovery, and internal metrics improved across nearly every key timeframe.

Friday’s market breadth lost momentum after Thursday’s broad surge, but the bigger picture did not materially break down.

Thursday’s breadth data confirms that the rebound remains intact, but it also shows a market that is advancing with less urgency than Wednesday’s surge suggested.

During the past 26 years, this small-cap stock ETF has underperformed the S&P 500.
