POLA is worth a look. Chart is oversold. 61% of shares held by insiders. NASDAQ. Cash explains more than 1/3 of the market cap. P/E under 20. Facing pricing pressures as competitors enter market, but revenues last month resumed upward climb. Institutional ownership rising. Short position is nearly 12 percent of float. ADX-PPO pincher chart. Recently went from having one major Telco as customer (Verizon) to having the top 3.
I've been buying a lot of shares under $5 (and some, regrettably, above $5).
I am obviously NOT an investment advisor.
