sell-to-cover financial

"Represents automatic 'sell-to-cover' transactions by an executing broker"

Sell-to-cover is when part of newly issued or exercised company stock is immediately sold to pay required taxes and fees, so the recipient keeps the remaining shares. For investors this matters because it reduces the number of shares insiders or employees actually hold after a grant, can create small, routine share sales that aren’t signal of cashing out, and slightly increases share supply on the market—like selling a portion of a paycheck to cover the tax bill.

weighted average price financial

"The price reported in Column 4 is a weighted average price"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

block trade financial

"These shares were sold as part of a block trade in multiple transactions"

A block trade is a large, privately arranged sale or purchase of a company's shares or bonds between big investors, often negotiated to avoid upsetting the public market price. Think of it like selling a truckload of goods directly to one buyer instead of unloading it on a busy street — it moves a lot of supply at once and can signal shifting demand, affect immediate liquidity, and influence short-term stock prices.
