The insider investment strategy is an investment strategy that follows the buying and selling decisions of insiders. It has historically outperformed the market over the long-run. The primary insiders have information advantage and the proven theory is that they as a group over time will do better than the average investor on the Stock Exchange. However in the world there are only a few investment funds that follow the insider trades, both of them were established in 2011. In America Catalyst Capital Advisors LLC 〔(【引用サイトリンク】 America Catalyst Capital Advisors )〕 manages 〔(【引用サイトリンク】 America Catalyst Capital Advisors )〕 Catalyst Insider Buying Fund .

Only transactions above 80.000 SEK were included (33% of all insider trades were excluded because they were too small). If there were no Purchases/Sales in 1,3,6 months after a company’s inclusion, it was excluded from the portfolio. All stocks are equally weighted.

And smallest in Large Caps insider Purchase portfolios. * ‘Insider effect’ fades away with longer holding horizon. * Sell signals are stronger than Buy signals. * Sell signals are the strongest when more than 50% of holdings are sold. * Buy signals are the strongest when signal transaction value is <80.000 SEK. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Insider investment strategy」の詳細全文を読む スポンサード リンク
