US CVS Health shares fell more than 12%, showing the maximum daily decline since January, and the company's capital fell by $14 billion, the Wall Street Journal writes. Investors reacted negatively to the company's decision to allocate approximately 91,000 retail pharmacies to an independent structure, while separating them from Atena's insurance division and the Caremark service. According to the publication, market participants doubt the prospects of a separate pharmacy chain and fear the loss of financial benefits.
