What is a low-float stock?

A low-float stock has few shares available for public trading. Demand surges can move the price sharply, and the move can reverse just as fast.

Do big one-day gainers keep rising?

Not reliably. Many give back part of the move, especially micro-caps without a lasting catalyst. Manage risk and do your own research.
