Aurora Innovation (AUR)

Dilution

The share count is up +4.4% in a year, so each share is a slightly smaller slice of the company. What dilution means.

Insider trades

Bought or sold on the open market

An insider buying with their own money is a stronger signal than a sale: people sell for taxes, houses and diversification. "Planned" sales were scheduled months ahead under a 10b5-1 plan. Source: SEC Form 4.

Famous investors who own it

From each fund's latest 13F, filed up to 45 days after the quarter ends, so it's old news by design. 13Fs only show US stock owned on the last day of the quarter: no short sales, and "added" or "trimmed" compares two snapshots, not actual trades. See what these funds bought and sold.

Failed trades

From the SEC's fails-to-deliver data, which runs two to four weeks behind. A spike can mean heavy short selling or just back-office delays; it isn't proof of anything on its own. Short interest isn't shown: FINRA's terms don't allow republishing it.

Share offerings

Selling new shares dilutes current owners. A "shelf" is permission to sell later; a 424B5 usually means a sale is actually happening.
