Rule 105b-1(redirected from Rule 105b1)
A plan in which an investor holding a long position on a security sets forth conditions under which the security will be sold automatically. The selling plan is particularly important if the investor has inside information because Rule 105b-1 of the SEC permits what would otherwise be insider trading as long as the process is set in motion automatically with a selling plan. This construction is controversial, with critics maintaining that selling plans are open to manipulation that allows what amounts to insider trading by stealth.
