Ridgetech Inc.

(NASDAQ:RDGT) stock swung wildly in Tuesday's session as retail traders piled into the low-float stock, fueling sharp price swings and heavy speculative trading.

The stock surged from the low-$1 range to more than $4 in premarket trading before reversing course and falling back toward $2.22.

The rapid moves underscored the heightened volatility often seen in thinly traded, low-float stocks.

The rally appeared to be driven primarily by retail day traders rather than company-specific news.
