USO ETF surges to highest levels since 2015, signaling potential oil market rally amid global energy shifts and crypto volatility like Bitcoin trends.

According to Eric Balchunas, $GLD has become the 12th ETF to enter the exclusive Hundo Billy Club, marking a significant milestone as the first commodity ETF to achieve this status. This development is particularly noteworthy given that GLD's assets have doubled from $50 billion just 18 months ago. Traders may find this growth indicative of increasing investor confidence in commodity-based ETFs, potentially influencing trading strategies focused on commodity markets.
