Where convertible securities stands now
As of 12 October 2026, Convertible Securities (CWB) ranks #61 of the 115 groups Zensei tracks by one-month return against the S&P 500. It is out of favor: it trails the S&P 500 on both rotation windows — 4.9 points behind over the past month and 2.8 points behind over the longer, time-shifted window. That is the Underperformers quadrant.
On the shorter tape, CWB's momentum is weakening: the intraday trend that carried the move is cooling across the shorter windows. CWB'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 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.
