Questions about MRK insider trading
Who bought Merck (MRK) stock recently?
No insider made an open-market purchase of Merck (MRK) stock in the last 12 months.
Are insiders buying or selling MRK?
Over the last 12 months insiders were net sellers of MRK on discretionary trades: $0 bought against $76.7M sold (scheduled and tax-related sales excluded).
What is a sell-to-cover or 10b5-1 sale?
A 10b5-1 sale is scheduled in advance under a pre-arranged plan, and a sell-to-cover sale is made to pay tax on vesting shares. Neither is a fresh decision to sell, so they say less about an insider's view than a discretionary sale.
