The read
Solar Energy (TAN) is out of favor: it trails the S&P 500 on both rotation windows — 4.8 points behind over the past month and 31.8 points behind over the longer, time-shifted window. That is the Underperformers quadrant. Ranked by one-month spread, it currently stands #88 of the 115 groups Zensei tracks.
On the shorter tape, TAN's momentum is weakening: the intraday trend that carried the move is cooling across the shorter windows. TAN'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 Invesco Solar ETF, whose 14 tracked holdings are led by FIRST SOLAR INC, NEXTPOWER INC CLASS A and ENPHASE ENERGY INC. Weighted by portfolio, the fund's holdings trade at roughly 27.9× earnings and 6.0× sales. The thing to watch from here is the one-month spread: underperformers only become interesting when the recent window turns positive first — until then, the market is voting elsewhere.
