Context
A 10b5-1 trading plan allows insiders to pre-schedule trades and is commonly used to avoid questions about trading on material nonpublic information. Sales under such plans are often routine and do not necessarily indicate a change in the insider’s view of the company. For retail investors, purchases are generally more indicative of positive insider sentiment than routine sales.
