About Joseph Baroldi's insider trades
Joseph Baroldi is EVP, Chief Business Officer at Ionis Pharmaceuticals (IONS). Since Jan 18, 2023, Joseph has reported no open-market purchases and 21 sales worth $7.1M on SEC Form 4. In the last 12 months: 8 sales ($2.6M).
9 sales (70% of the value sold) were made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so they say little about how the insider sees the stock today.
Their filings also include option exercises (14 filings), grants and awards (13 filings). These aren't open-market trades and aren't counted above.
How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every IONS insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
