RE:API has a 9mm barrel drawImagine having a real job where you were asked to come up with an estimate and at the end of the week your estimate was off by a factor of 60X. A real company would think you were an idiot and would tell you to clean out your desk and get lost. Weekly API oil data is as random as the weekly lotto numbers.
I doubt it will make any significant difference to oil stocks tomorrow. Someone will see that the Gasoline number went up so oil and oil stocks are as likely to go down as they are to go up. You need about a month of 9M barrel draws before anyone seems to take the API numbers serious.
