Global equity markets are trading mixed following the release of stronger-than-expected U.S. producer price inflation data this morning.

iShares Silver Trust (SLV) [-1.5%]
iShares Silver Trust (SLV) has experienced a decline of 1.5%, coinciding with a drop in spot silver prices, which have fallen below $78 per ounce, reflecting an intraday decrease of 1.53%. Silver's decline aligns with a broader downturn in precious metals, as gold has also decreased by 2%. This movement is attributed to a strengthening US dollar, influenced by geopolitical tensions, including Israeli strikes on Iranian gas facilities and operational disruptions in Iran's South Pars gas field. Recent social media discussions reflect a cautious sentiment regarding SLV, noting the declines in both gold and silver prices.

Social media discussions have noted that GDX has breached both its 50-day moving average and trendline support, with critical support levels highlighted at February lows of $92. A bearish sentiment is evident, with reports of 90 puts going to cash for options expiration on Friday. Additionally, gold prices have declined by over 2.5%, likely influencing the movement in GDX.
