T3 Defense Inc. (NASDAQ:DFNS) stock surged nearly 22% Tuesday as traders piled into the defense technology company’s tightly held stock.

The Nasdaq gained 0.65%, while the S&P 500 rose 0.27%. However, T3 Defense’s move far outpaced the broader market.

What’s Going On?

T3 Defense has remained highly volatile since completing a 1-for-125 reverse stock split.

The company completed the split to meet Nasdaq listing requirements. However, the smaller public float can amplify price swings when speculative trading volume rises.
