There have been 20,632 shares sold by insiders during the last 30 days. All these shares were sold pursuant to a Rule 10b5-1 plan.

SEC Rule 10b5-1 is a regulation enacted by the United States Securities and Exchange Commission (SEC) in 2000. The SEC states that Rule 10b5-1 was enacted in order to resolve an unsettled issue over the definition of insider trading, which is prohibited by SEC Rule 10b-5. After Rule 10b5-1 was enacted, the SEC staff publicly took the position that canceling a planned trade made under the safe harbor does not constitute insider trading, even if the person was aware of the inside information when canceling the trade. This staff interpretation raises the possibility that executives can exploit this safe harbor by entering into 10b5-1 trading plans before they have inside information while retaining the option to later cancel those plans based on inside information.

For example, a CEO of a company could call a broker on January 1 and enter into a plan to sell a particular quantity of shares of his company's stock on March 1, find out terrible news about his company on February 1 that will not become public until April 1, and then go forward with the March 1 sale anyway, saving himself from losing money when the bad news becomes public. Under the terms of Rule 10b5-1(b) this is insider trading because the CEO "was aware" of the inside information when he made the trade. But he can assert an affirmative defense under Rule 10b5-1(c), because he planned the trade before he learned the inside information.

In general, it is a safer way for an insider to sell shares pursuant to a Rule 10b5-1 trading plan than without it.

Only Silicon Laboratories has seen intensive insider selling during the last 30 days.


There have been four different insiders selling Silicon Laboratories, and there have not been any insiders buying Silicon Laboratories during the last 30 days. Two of these four insiders decreased their holdings by more than 10%. Silicon Laboratories has an insider ownership of 7.32%.

Silicon Laboratories has a $44 price target from the Point & Figure chart. I believe there is an opportunity for a short entry with the $44 price target. I would place a stop loss at $54, which is the eight-year high. The three main reasons for the proposed short entry are a bearish Point & Figure chart, relatively high P/E ratio, and the intensive insider-selling activity.
