48fords,
You asked what to do about these five stocks: CWBHF, FSLY, NVTA, PRLB, VTRS. The horse is already out of the barn on all of them, and your basic mistake is this. You went ‘long’ rather than ‘selling short’.
Whoever told you to buy those stocks is an idiot who doesn’t understand investing. Whatever he/she/they are telling you, you need to do the opposite to make money.
