These are very speculative investments. I would be very careful to place any money at risk here that you cannot afford to lose.
In general, investing in individual stocks is akin to rolling the dice and not likely to yield you much success. Markets are too efficient and there are too many professional investors competing against you for you to have much chance outsmarting them by finding a "winning" stock they may have overlooked.
Good investing is about keeping costs low, tax efficiency high, being highly diversfied and only taking risk where the potential reward is worth it. Anything else is gambling.
