description: "$Foxx Development(FOXX.US) surged +83% in a single day: it was added to Qualcomm's partner directory, plus news of a real estate collaboration, causing it to jump in both pre-market and after-hours trading.The problem is that a consumer electronics small-cap stock of this size has deeply negative profit margins. Can a directory-level news item sustain an 80% gain? I think it's more like a low-float stock being ignited by capital, a pulse where the quality of the catalyst doesn't match the magnitude. Chasing in without a position is highly likely to mean catching the last pass."
