Jim Cramer, host of CNBC's 'Mad Money,' has advised investors to divest from volatile stocks, particularly those in the quantum computing sector, citing market froth. This recommendation comes in the wake of significant losses in quantum computing stocks, with IonQ Inc. ($IONQ) experiencing its largest loss in history at -42%. Other quantum computing companies such as Rigetti Computing ($RGTI) and QUBT ($QUBT) also saw substantial declines, with losses of -48% and -47% respectively. Cramer's comments were part of his rapid-fire 'Lightning Round' segment, where he also expressed a negative stance on QuantumScape, urging investors to sell.
