About Timothy C K Chou's insider trades
Timothy C K Chou is a director at Teradata (TDC). Since Nov 16, 2012, Timothy has reported no open-market purchases and 21 sales worth $3.2M on SEC Form 4. In the last 12 months: 1 sale ($191K).
1 sale (4% of the value sold) was made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so it says little about how the insider sees the stock today.
Their filings also include grants and awards (33 filings), shares returned to the company (1 filing). 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 TDC insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
