Since the lows in 2009, the Nasdaq 100 and Semiconductors (NYSE:SMH) have been much stronger than the S&P 500 (upside leaders).
The NDX 100 (left chart) and semiconductors are very near their 2018 highs, which happens to be all-time highs as well.
If both break out at each (1), they will send a bullish message to tech and the broad markets as well.
Keep a close eye on both, as breakouts would send a quality bullish message from leadership.
