Summary by Sections Gold Market Performance - Gold has experienced a nearly parabolic increase, rising 20% since late August [1]. - The Percentage Price Oscillator (PPO) for GLD has reached an all-time high, indicating it is more richly valued than at any point in the last 20 years, with a historical precedent of a nearly 50% decline following similar peaks in 2012 [2]. Investment Strategies - Investors in GLD have seen solid gains recently, and a recommended strategy to mitigate risk while retaining upside is to reduce their position size, effectively locking in some profits [5]. - The use of leveraged ETFs, such as the Direxion Daily Gold Bull 3X Shares ETF (BAR), allows investors to "downshift" after a profitable trade by selling GLD and reallocating a small portion into BAR for increased volatility [5].
