Reddit reviews Black Edge: Inside Information, Dirty Money, and the Quest to Bring Down the Most Wanted Man on Wall Street

I don't know about that. There's been a few statistical studies suggesting that insider trading is really common (trading volume in stocks tends to go up right before a major announcement).This book does a deep dive into one case of trading that actually got exposed and prosecuted, but the author suggests that it flies under the radar a lot of the time.

​

Honestly I think there's a "right" way to do insider trading, and Mychal Kendricks just didn't know it.

• Oftentimes individuals who work for a corporation are privy to non-public information.
  
  
• For example, maybe the new drug the company is developing is found to have terrible side effects. So while investors have been investing and the stock price has been going up and up, once the bad news hits, the stock price will drop like a rock.
  
  
• So before the bad news goes public, the insiders sell all of their stock before it tanks.
  
  
• Obviously this is not fair to the other investors and is also quite illegal.
  
  
• Whether insiders profit by buying stock to reap the profit before some good news hits or sell stock to avoid a loss, they are breaking the law.
