The SPDR Gold ETF, a major gold-backed exchange-traded fund, experienced significant market activity between August 21 and October 20, with approximately $13 billion in inflows. However, recent market volatility has led to a $2.6 billion outflow over the past five trading days, representing about 20% of the previous inflows. This movement coincides with gold's retracement to the 0.382 Fibonacci level since August 21, indicating a potential shift in investor sentiment.
