The U. S. Securities and Exchange Commission periodically charges individuals with insider trading and claims those individuals have made unfair profits. Given this, you would be most apt to argue that the markets are less than form efficient.

Markets are less than strong form efficient

Explanation:

The strong form efficiency is an economic hypothesis that says that all relevant information about a company is reflected on the value of its stock. This means that all investors are in the same playing field as long as the value of the stock is the same for everyone, and that not even insider trading can provide any advantages to an investor.

The U.S. Securities and Exchange Commission clearly does not accept that hypothesis because it punishes insider trading on the basis that it does provide unfair advantages to investors.
