POLA is not a pincher, and chart looks pretty bad right now.
It is a small company that makes top-notch generators. They used to supply generators for power continuity at our nuclear missile silos. Their revenues were cranking higher, but then they ran into capacity problems followed by order problems.
I think the selling is way overdone -- but who am I to say, given how badly I've predicted this stock so far.
Another mid-term play is DAIO. It has cash equal to about half its market cap. And it is a market leader in security for the internet of things.
Those are my two sort of speculative small-cap (but not penny stock) plays.
Mostly these days, I just do mutual funds...
I am obviously NOT an investment advisor.
