A Five Cent Meme Stock Just Made Up 15% of U.S Trading Volume

Shares of little-known Healthcare Triangle Inc. drew major attention on Thursday, emerging as the most actively traded stock across U.S. exchanges and serving as yet another sign of how speculative enthusiasm continues to whip up dramatic market moves.

‍

The healthcare IT company, which typically flies under the radar, saw its stock more than double in price, climbing just above five cents. Trading activity exploded, with more than 3 billion shares changing hands throughout the day. That single name accounted for roughly 15% of all shares traded across U.S. markets on Thursday, according to Bloomberg data—a staggering figure for a company of its size.

‍

Healthcare Triangle’s stock opened with a stunning 138% jump and ended the session up 115%. There was no clear catalyst for the surge—no press releases, earnings updates, or major headlines—and the company did not respond to requests for comment on the sudden move.

‍

The total dollar value of shares traded came in around $150 million for the day, which is particularly remarkable given that this figure is nearly seven times Healthcare Triangle’s market capitalization. In other words, the trading activity vastly outpaced the company’s actual size and value.

‍

This event is the latest example of the speculative fervor sweeping across segments of the stock market. Similar to past waves of retail-driven trading, this latest surge in interest is lifting highly speculative, often low-priced stocks with limited fundamentals. Recently, companies like Kohl’s Corp., GoPro Inc., and Krispy Kreme Inc. have experienced similar sudden jumps in share prices, spurred largely by retail investors rather than institutional news or performance-related developments.

‍

Earlier this week, Opendoor Technologies Inc. also saw a flurry of trading activity and a sharp share price increase, pointing to the broadening of the so-called “meme stock” movement. These episodes are characterized by rapid price increases in companies that have captured the attention of retail investors—often on social media platforms like Reddit’s WallStreetBets—without significant changes to their underlying businesses.

‍

While the list of stocks pulled into this whirlwind continues to expand, many of these rallies have been highly unpredictable and short-lived. The brief nature of the spikes raises important questions about whether these companies can capitalize on their moment in the spotlight by raising new capital, as AMC Entertainment Holdings Inc. and GameStop Corp. famously did during the first meme stock frenzy in 2021.

‍

In that earlier wave, those companies were able to take advantage of inflated share prices by issuing new stock, giving them a financial lifeline that helped them navigate ongoing business challenges. Whether this new crop of meme stocks—including Healthcare Triangle—will follow suit remains uncertain, especially as investors grow more cautious about how long these rallies can last.

‍

It’s also worth noting that Healthcare Triangle has seen little media attention and doesn’t typically attract a large following among analysts or institutional investors. Its sudden prominence underscores how investor sentiment alone, rather than fundamentals or earnings potential, can drive immense trading volume in today’s market.

‍

The sheer scale of Thursday’s activity was out of proportion with the company’s size, and the lack of accompanying news only deepened the mystery. However, this type of trading behavior isn’t entirely new. In fact, it has become a somewhat familiar pattern in recent years, especially as zero-commission platforms and social media have given retail traders easier access to markets and amplified their impact.

‍

These sudden bursts of speculative trading often resemble flash fires—quick to flare up, but equally quick to fade. That volatility presents both opportunities and risks. On the one hand, retail investors who time the surge correctly can see significant short-term gains. On the other, those who get in too late or hold on too long often suffer steep losses.

‍

For companies like Healthcare Triangle, the real challenge lies in navigating this sudden wave of attention. If management can move quickly, there may be opportunities to raise capital, restructure operations, or invest in growth initiatives. But given the fleeting nature of such rallies, acting swiftly is crucial.

‍

Ultimately, Healthcare Triangle’s meteoric rise on Thursday is a fresh reminder that market behavior in the age of retail-driven speculation can defy traditional logic. While fundamentals still matter in the long run, short-term price action is increasingly influenced by momentum, social media sentiment, and crowd psychology—factors that can lift obscure stocks into the limelight in a matter of hours.
