Ballard Power slides 11.1% as sellers retake control after the bounce

August 21, 2026

Our view last week

Ballard Power buyers step back in: the week closes up 3.1%, with 79% of volume on the bullish side — a sharp reversal from the selling seen seven days earlier. The technical picture stays cautious though: cash flow improves but is still negative, and momentum has not turned yet. On the daily chart the stock still broke below the trigger level in the 2.75 area, and the sequence of lower highs from the 3.2 to 2.9 area hasn't been invalidated. The trade remains up 36%.

This week's summary

Last week's bounce fades fast: Ballard Power shares slide 11.1% as sellers retake control, taking 86% of the week's volume. It's the mirror image of seven days earlier, when buyers held 79% of the flow. Our technical analysis is tracking the short position, now in its 11th week of management and up more than 40%, as the stock keeps carving out lower highs below the 2.9 area — a case worth watching for anyone following price action trading.
