QTREX Quantum Stock Extends Rally After 97% AME Yield Milestone

QTREX Quantum Ltd. shares surged after the company said its Additively Manufactured Electronics technology, or AME, had moved from a development setting to the production floor at one of the largest U.S.-based interconnect manufacturers. AME means electronics made with additive, layer-by-layer manufacturing rather than only conventional assembly. The stock closed Monday at $2.20, up 70.54%, after trading between $1.45 and $2.62, and Google Finance showed the shares at $2.38 in Tuesday premarket trading, up another 8.18%.
