Elon Musk taunted the SEC with his tweet "naughty by nature."

The value of Tesla stock has risen over 16% in trading last Monday following Elon Musk's signing of a deal with the SEC on the weekend. The gains on Monday erased the 14% decline of Tesla stock on Friday after the lawsuit was filed late Thursday by the SEC.

The dispute between Musk and the SEC occurred after Musk tweeted on August 7 that he had secured the funding needed to take Tesla private at a price of $420 a share. However, it soon became obvious that the commitment for this funding by the sovereign wealth fund of Saudi Arabia had only been made informally.  

For this reason, on Thursday the SEC filed a suit against Musk charging securities fraud. At first, Musk claimed he was going to fight against the charges, but following the rapid decline of Tesla's stock price, he reconsidered his position and settled the lawsuit on Saturday.
