In a tumultuous day for the stock market, the Dow Jones Industrial Average stood as an outlier, displaying positive movement late Friday afternoon. The tech sell-off deepened, causing the S&P 500 to dip below a crucial psychological level. Indexes remained mixed as Israel launched a retaliatory attack on Iran, adding to the uncertainties in the global market.

As the sell-off intensified, prominent tech stocks experienced significant declines. Nvidia, Meta Platforms, and Amazon.com all fell below their 50-day moving averages, indicating a bearish trend. Super Micro Computer also experienced a drastic drop in its share value.

Meanwhile, Bitcoin remained strong, hovering around the $64,000 level ahead of the anticipated fourth halving event. The halving is expected to decrease miners' rewards, thus reducing the circulation of new bitcoins over time.

The Dow industrials managed to hold on to a 0.4% gain, while the S&P 500 fell by 0.9% and dropped below the crucial 5,000 level. Among the various S&P sectors, utilities, energy, financials, and consumer staples fared relatively well. On the other hand, communication services, technology, and consumer discretionary sectors witnessed a decline. The Nasdaq suffered the most significant losses, plummeting by 2.2% to reach its daily lows.

Despite higher trading volumes compared to the previous day, market breadth remained mixed. Advancers outweighed decliners on the New York Stock Exchange (NYSE), while decliners held a slight edge on the Nasdaq. However, fewer stocks were making new highs, indicating mounting pressure on the market.

The small-cap Russell 2000 index reversed its early gains, falling by 0.6%. The Innovator IBD 50 ETF experienced a more substantial decline, plummeting by over 2%. This further highlights the growing market pressure.

In specific stock developments, American Express rebounded dynamically on strong sales and higher-than-expected earnings per share in the first quarter. Likewise, UnitedHealth contributed to lifting the Dow, while stocks like Amazon.com, Intel, Microsoft, and Apple weighed it down.

Netflix, despite delivering strong first-quarter results, suffered a 9% drop due to their weaker-than-expected Q2 sales outlook. The stock triggered a sell signal by dipping below the 50-day moving average in significant volume, making it one of the worst performers in both the Nasdaq and the IBD MarketSurge Growth 250.

Intuitive Surgical experienced a soaring start, reaching resistance at its 50-day moving average before settling near Thursday's closing price. The company reported a notable 11% rise in sales and a 22% increase in earnings per share in the first quarter.

Looking ahead, investors are keeping a close eye on Tesla, as the company is scheduled to release its first-quarter earnings on Tuesday. Shares have been trending lower, staying below the 50-day moving average since January. Analysts anticipate a 5% decline in sales and a substantial 42% plunge in earnings per share.

In conclusion, the Dow Jones Industrial Average remained a bright spot amidst a tech sell-off and escalating tensions between Israel and Iran. As the market endured fluctuations, various prominent tech stocks suffered significant declines, while others showed resilience. Bitcoin remained steady ahead of the fourth halving event. With ongoing uncertainties and market pressure, investors are advised to stay informed and cautious.
