Why Is NeoGenomics ($NEO) Stock Down -12.70% Today? (Find out why any stock moved today on Tickeron.) NEO shares fell roughly 12.7% in Tuesday's session, giving back a large portion of recent gains. The primary catalyst was a multi-layered executive and board leadership succession plan announced after Monday's close. Investors were also disappointed that the company did not raise full-year guidance despite reporting preliminary third-quarter revenue above consensus. The sell-off was company-specific — broader indices traded higher, confirming the move was not driven by macro or sector weakness. Analyst upgrades provided only limited support as traders weighed near-term execution uncertainty tied to the transition. $NTRA $ADPT $RVTY $SHC
