The rise of the Financials ETF (XLF) from March 2020 seems rather parabolic when compared with prior rallies over the past two decades, as shown on the following monthly chart.
A pullback may be just around the corner.
A drop and hold below major support at 30.00 could see this sector plummet to around 25.00, or, even 20.00, in short order.
Keep an eye on my post on the US Dollar as a cross-reference for clues.
