The United States Oil Fund (NYSEArca: USO), which tracks West Texas Intermediate crude oil futures, has recently seen what was once an impressive rally wane in dramatic fashion. Just a few weeks ago, USO was sporting a double-digit gain over a month.

Now, the ETF’s one-month loss is north of 10%, putting it back in correction territory. That and few investors look to be sticking around or adding new positions to support the again flailing ETF. Still high supplies and an ongoing lack of clarity on output reductions continue plaguing USO and other oil-related exchange traded products.

On the other hand, there might be some good news for energy equities. Good news could come in the form of waning correlations between oil prices and equities. As oil prices drag on oil company shares, the correlation between stocks and oil potentially weakened to some extent, which may have benefited broad benchmark investments in the event of further crude oil weakness. However, with oil prices rebounding off 13-year lows, investors may be under-allocated toward the energy sector.

There might be something to that skepticism as many of the world’s major ex-U.S. producers of oil have not displayed a willingness to pare production. Even the output reductions in the U.S. have been modest. The good news is U.S. shale output is slightly declining, but challenges remain on the output front from OPEC producers.

OPEC has hinted at its desire to limit production in face of the prolonged low oil environment. However, Iran, which has just recently re-entered the global oil market, is only just starting to ramp up production, potentially putting a damper on plans for a OPEC cut.

“Oil investors withdrew most money from the United States Oil Fund last month in almost five years, helping stall a rebound that pushed crude prices up by the most since April 2015. The biggest exchange-traded fund that tracks U.S. benchmark West Texas Intermediate had an outflow of $598.9 million in March, the biggest since April 2011, according to data compiled by Bloomberg. The fund held 91,828 contracts of May futures as of yesterday, or 17 percent of the contract’s open interest. WTI rose 14 percent in March before dropping almost 7 percent so far this month,” reports Moming Zhou for Bloomberg.
