Is oil market efficient or inefficient and why so ?

Question

If oil prices are efficient (which means oil prices reflect all information, including public and private) then are they strong, semi-strong or weak form efficient ? and why so ?

Thanks Mademan. But as we all saw oil market reacted instantly in recent mid-east crisis. Same thing happened at the time of Hurrican Katrina...Obviously mathematically or theoretically its not possible for a market ot be completely efficient but compared with other stocks dont you think oil market reacts way more sharply to a news and hence can be termed as strong ? by the way, do you know of any recent financial articles analysing change in oil prices in contect of recent mideast conflict ?
Thanks,

Answer 1

Great "theories," but mostly Doublespeak.

Instead of a "radom walk," take a reality walk through the crowds of rich traders on the trading floor making money in your "efficient" markets.

Even if all markets are effecient, they will contain inefficiencies, otherwise nobody could make money with technical analysis.

Read a book by a trader, not that Phd theorist crap.

Answer 2

they are semi-strong and reflect all information available to the market. it isnt strong because strong is nearly impossible, as it would have to reflect all available information at the exact time the information was created. semi-strong reflects available information within a reasonable time-frame. it isnt weak, because investors would not be able to earn a consistent return.

hope this helps.

Answer 3

Yes, Oil market is efficient because our economy depends mostly on oil.

Reads the Federalist papers. it is demanding to describe why own freedom is so significant, and why this tremendous usa became depending upon YOUR rights. performance should be enforced, hostile to the choose of the individuals. you won't be able to be a loose American and cry out for administration jointly.
