Why insider trading matters?

Numerous studies have examined whether there is evidence that U.S. insiders systematically trade on private information despite the legal deterrence. The consensus appears to be that insider purchases (but not sales) tend to be followed by positive abnormal stock price performance, particularly for small growth stocks.

Insider Smart

Delta Airlines (DAL) - From an insider's perspective: airlines are the first ones to go under due to the pandemic. A lot of concerns were raised on possible bankruptcy especially amid by the dump from Buffett. However, insiders of Delta were bold enough to buy when Buffett was fear. And Delta is the only airline bought by insiders post-Buffett-dump.

Enphase Energy, Inc (ENPH) - ENPH was $10+ in 15Q1 then dropped to $2 and eventually went under $1. From 15Q4 to 17Q4 it built a 2-year-long base then BOOM! Stock went as high as $70 and likely will make a new high. Catch one or two moves like this you can retire early. One hint before the big move was that CEO and CFO were constantly accumulating, this kind of information is priceless.
