On December 13th about thirty minutes before the close, my insider service, SEC Analytics, posted an insider Buy for ALLOY INC (ALOY); the CEO had bought $108K worth of stock on the open market two trading days earlier, on December 9th. At the time of the posting, ALOY was available to buy at the very same price range that the insider had bought his shares, $5.88 - $5.90 a share. Before the close, ALOY was trading above $6.00, to as high as $6.10 on very heavy volume.
The next morning, December 14th, ALOY opened at $5.97 a share and traded strong all day long, trading as high as $6.51 before closing at $6.40. On December 15th, ALOY once again opened strong, at $6.43, trading as high as $6.68 as I write this.
This is typical of a one of the better insider buying trades:
A late afternoon signal that carries into the next day and beyond, for a 10% or better pop. A day-trade on the afternoon of the signal provided the potential of a 4% gain, the days immediately following the signal expanded the potential gain to over 10%.
