Why are these symbols considered higher risk?

These symbols are considered higher risk as they may experience elevated volatility, lower liquidity, significant price swings, increased operational risk, or settlement concerns.

Many of these securities have undergone serial reverse stock splits, which may increase risk for broker-dealers, clearing firms, and clients.

For symbols that are short-sale eligible, clients should also be aware of additional risks specific to short selling, including limited share availability, locate/borrow costs that can change throughout the day, and the potential for a forced buy-in if shares can no longer be borrowed.
