CRUDE OIL
After rallying to a 2-week high at 75.72, crude oil price retreated more than -$1/bbl. The front-month WTI contract ended settled at 73.97, down -0.78%, on Friday. On weekly basis, the contract surged +5.61%, halting the severe selloff since May 3. In May, WTI futures slumped -14.1%.
Crude surged on OECD GDP revision and most importantly the much awaited drawdown in Cushing stockpiles. As driving season approaches and refinery utilization inches up, it can give a fillip to Crude and WTI – Brent

Crude oil fell more than 20 % from its high. Technically if any asset class fall more than 20 % from its highs enters a Bear Market. I believe crude oil also has entered a short term bear market or the upside looks limited for the time being. So any retracement to Fibonacci levels can be a good shorts
WTI BRENT
Finally WTI- Brent spreads managed to see the positive territory
the three primary reasons were
1. Driving season which pushes the demand for gasoline in US
2. Refinery Utilization going up after their maintenance is over
3. As Euorope Crisis deepens the demand for Brent Crude may be affected which will keep it at a discount as compared to WTI crude

The Gasoline Demand is also looking strong for this year
