The biggest problem with U.S. insider trading laws is that the U.S. has no insider trading law.

It’s true. The nation’s seminal securities statute, the Securities Exchange Act of 1934, while broadly outlawing securities fraud, never even employs the phrase “insider trading.” And over the subsequent 83 years, while Congress has occasionally increased the penalty for insider trading, it has never gotten around to defining what it is.
