Company insiders (directors, senior officers and anyone owning more than 10% of the shares) must report every trade in the company's shares to the US Securities and Exchange Commission on Form 4, within two business days of the trade. Open-market buys matter most: an insider spends their own money at the market price, usually because they think the shares are cheap. Sales say less, because insiders sell for many reasons (taxes, a house, spreading their wealth, pre-set trading plans). Grants, option exercises and shares withheld for tax are part of pay, not a view on the price. Trades are filed within two business days, so this list is usually a day or two behind the trade itself. Values are shares × the price reported in the filing. Date = the day of the trade.

What is a Form 4?
The form a US company's directors, senior officers and 10% owners must file with the SEC within two business days of buying or selling the company's shares.
Do insider sales at Alnylam Pharmaceuticals, Inc. mean the stock will fall?
Not necessarily. Insiders sell for taxes, diversification or pre-set trading plans (marked "Pre-set plan"). Open-market buys tell you more, because insiders buy for one reason: they expect the price to rise. Information only, not investment advice.
What do grant, option exercise and tax withholding mean?
A grant is shares given as pay. An option exercise turns stock options into shares. Tax withholding is shares the company keeps to pay the insider's tax when shares vest. None of them is a trade at the insider's own choosing in the market.
