The largest ETF following gasoline futures is on a five-day losing streak and down more than 5% for the week. Lower oil and gas prices spell relief at the pump for consumers but also signal concerns about the global economy.

The $115.3 million U.S. Gasoline Fund (NYSEArca: UGA) was down 3.2% on Friday near its 200-day simple moving average, a level it hasn’t traded below in 2012.

Gasoline futures fell to an 11-week low Friday after the April employment report came in weaker than expected. Gas prices dropped below $3 a gallon. [Gasoline ETF Highest in Three Years as Prices Near $4]

“It’s the combination of weak economic data across the globe and the realization the market is well supplied,” said Phil Flynn, vice president of research at PFGBest, in a Bloomberg report.

The gasoline ETF was up 11% year to date heading into Friday’s trading.
