The read
CleanTech (CTEC) has just turned the corner. Over the longer, time-shifted window it trailed the S&P 500 by 30.5 points, but over the past month it has moved decisively ahead of the market — a 7.8-point edge that puts it in the Emerging quadrant. Ranked by one-month spread, it currently stands #21 of the 115 groups Zensei tracks.
On the shorter tape, CTEC's momentum is weakening: the intraday trend that carried the move is cooling across the shorter windows. CTEC's relative-strength line has broken below its long-term average — the long-term outperformance trend is no longer intact. Both signals point the same direction here: the market is not rewarding this group on either horizon.
The exposure comes via Global X CleanTech ETF, whose 19 tracked holdings are led by BLOOM ENERGY CORP CLASS A, FIRST SOLAR INC and NEXTPOWER INC CLASS A. Weighted by portfolio, the fund's holdings trade at roughly 105.8× earnings and 7.5× sales. The thing to watch from here is confirmation: emerging groups that hold a positive one-month spread long enough for the longer window to turn are the classic early-rotation entries — the ones that fail fall back quickly.
