"Mad Money" host Jim Cramer points out that market momentum has shifted to the bullish side, coinciding with a sharp reversal in Bitcoin's price and triggering massive short position closures. CoinGlass data shows Bitcoin's price surged above $71,000, causing over $300 million in short positions to be liquidated in just four hours. Overall, short positions exceeding $810 million were closed within 24 hours, primarily from Bitcoin and Ethereum positions. Cramer links this rebound to current market conditions, arguing that shorts are currently retreating amid a general increase in risk appetite and pullbacks in safe-haven assets such as gold.
