Penny stock investing doesn't have to involve super risky stocks that can erase your retirement money. Penny stock recommendations also can encapsulate low-priced stocks that are more stable, trading at bargain prices and low valuations. These bargain investments trade for between $1 and $3 -- very cheap compared to traditional equities. Though they are not trading for a few cents like some penny stock recommendations, these stocks are worth the extra share price because they have added stability.
