$TLT monthly chart screaming oversold. Price sitting way below the lower Bollinger Band, making new all-time lows while building bullish divergence for four years straight. Classic rubber band stretched too far setup. When bonds finally catch a bid, the snap back could be violent. Not saying it's time yet, but the technical setup for a mean reversion trade is getting hard to ignore. Duration has been a widow-maker, but risk/reward starting to flip.
