Nvidia's shares have experienced a notable recovery during Tuesday's trading session, following a series of declines over three consecutive days. This movement was a hot topic on the financial news show "Market Domination," where Interactive Brokers Chief Strategist Steve Sosnick shared his insights on Nvidia's impact on the tech sector and its influence on the wider stock market.

According to Sosnick, Nvidia has been a leading force in the technology sector's expansion and has played a significant role in the overall market uptrend. Despite some investors raising their eyebrows at the recent ups and downs of tech stocks, Sosnick suggested the fluctuations were not concerning, attributing them to end-of-quarter adjustments that resulted in portfolio rebalancing rather than a loss of confidence in the sector.

Discussing Nvidia's valuation, Sosnick portrayed the tech giant as being fairly priced, acknowledging its impressive revenue generation. He emphasized, however, that the key question for investors was whether the company's stock price already reflected its future growth.

Sosnick also touched on the psychological pressure that institutional portfolio managers face, coining the term "weaponized FOMO" (fear of missing out). He described how managers were driven by the need to keep up with their peers, leading them to invest heavily in high-performing stocks like Nvidia, which in turn has intensified the clustering of investments in the tech sector.
