PANews 1月23日消息，据CoinDesk报道，CryptoQuant数据显示，比特币的夏普比率已深入负值区域，达到了2018-2019年以及2022年市场暴跌期间的水平，表明其风险调整后的表现不佳，当前的高波动性与疲弱回报不匹配。这一指标衡量的是相对于无风险利率的超额回报与波动性的比值。其转为负值意味着持有比特币所获得的回报已无法补偿其价格剧烈波动的风险。尽管比特币价格已从2025年10月超12万美元的历史高点回落至9万美元附近，但市场波动性依然高企。
历史数据显示，夏普比率的负值状态可能在价格停止大幅下跌后仍持续数月，例如在2018年末和2022年的漫长熊市中。分析师指出，该比率并非精准的底部信号，但显示风险回报已重置至历史上主要行情启动前的水平。市场关注的通常是该比率能否持续回升至正值区域，这通常意味着回报开始超过波动，与新一轮牛市启动更为吻合。目前尚未出现此类转势迹象。
