Pros: small market cap, massive projected growth in revenues, driven by new customers and new markets; seemingly strong and (appropriately) cautious management. little-to-no competition.
The competition question is most interesting to me as I haven’t seen it discussed here. Watching the first CEO interview highlighted here by @JabbokRiver42 it sounded like they have no competition, though the CEO didn’t explicitly say that. This article seems to suggest that some companies do their own testing. A Japanese company called Advantest might be a competitor, but I’m not clear if they sell the same products in the same markets.
Cons: I guess just that the stock has run up a lot, growth stocks in general have run up a lot and they still need to execute. Probably the biggest con for me is that this is a highly technical industry I know essentially nothing about. A big reason that my largest positions–by a lot–are PGY and SOFI is that I feel I understand the businesses a lot better.
