(Bloomberg) --For the past year, Saudi Energy Minister Prince Abdulaziz bin Salman has fought a war of words with oil speculators. Now, he’s taking his message to the heart of Wall Street. Prince Abdulaziz is scheduled to speak June 16 at the Robin Hood Investors Conference, a red-carpet event that brings together luminaries of the U.S. hedge-fund industry such as Paul Tudor Jones, Ray Dalio and Stanley Druckenmiller, and rising stars like Cathie Wood.
