Hitek Global up 350% in a day, GrowHub up 288%, and Hub Cyber Security almost doubled — all three are micro-cap stocks with extremely small float. Hitek just completed a reverse stock split recently, further compressing its float.

This magnitude of price movement can hardly be matched by any fundamental news; it's more of a pulse caused by low float and capital competition. My understanding is that this kind of volatility is basically unrelated to company value, comes and goes quickly. Those without positions shouldn't be lured by the gains to chase.
