The Trifecta List
Quantumsphere has never had a Trifecta signal in the record — not an Early signal, not a confirmed one — since the record began in January 2022. It is scanned after every trading day’s close along with the full US-listed universe; so far it has never met the conditions.
That’s the whole record for this stock: the chart and the basics above, and nothing to grade.
The list is the public track record: every stock that has signaled, logged, confirmed, and graded.
