About Mark Robert Tobin's insider trades

Mark Robert Tobin is a director at LIGHTBRIDGE (LTBR). Since Mar 28, 2022, Mark has reported no open-market purchases and 5 sales worth $263K on SEC Form 4. In the last 12 months: 1 sale ($135K).

2 sales (34% 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 grants and awards (9 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 LTBR insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
