Low-Price Stock Screening: Liquidity Floor at 1 Million Daily Shares, PDT Equity Rule at $25,000

6/28/2026

Benzinga analyst Ryan Peterson identifies stocks priced below $10 as functional short- and medium-term trading instruments, but sets one structural filter before any valuation question: daily volume of at least 1 million shares.

The downside on any stock is fixed at zero, making the absolute dollar loss on a sub-$10 name arithmetically bounded — but thin liquidity, not the price level, is the risk Peterson flags most consistently.

Commission-free retail platforms including Robinhood, Webull, TD Ameritrade, ETRADE, and Public serve the entry tier; Interactive Brokers and TradeZero serve higher-activity accounts with distinct cost structures and regulatory constraints.

Liquidity Is the Structural Screen, Not a Secondary Check Below 1 million shares of daily volume, bid-ask spreads widen, large orders move price, and exits become costly — mechanics that produce the sudden unexplained moves Peterson attributes to thinly traded names.
