Why do people think that SLS, RKLB, and ONDS are good stocks? Aren’t they penny stocks and susceptible to pump and dump? Furthermore, SLS is a biotech stock, which is especially volatile and news-based. For example, if trial 3 doesn't go well or the FDA doesn't approve it, the stock will tank. Furthermore, RKLB and ONDS are both unprofitable.
TL;DR: Should I invest in SLS/ONDS? Is it a good decision?
