Google compensates for Nvidia's decline as major companies boost market value by $420 billion in three days.

Tech Rally: Eight major US tech firms experienced a $420 billion rally in three days, driven by a favorable ruling in Google's antitrust case, which allowed the company to maintain its market position while requiring it to share search data with rivals.

Market Reactions: Alphabet's shares rose over 10%, and Apple benefited from the ruling as it retained its deal with Google. Meanwhile, Broadcom announced a significant deal with OpenAI, boosting its stock by 13%.

Legal Challenges: Despite facing a €2.95 billion fine from the EU for anti-competitive behavior, Alphabet's stock remained stable, indicating investor confidence in the company's future.

Mixed Performance: While Nvidia and Microsoft saw declines in their stock prices, Tesla's shares rose 5% following news of a new pay plan for CEO Elon Musk, aimed at motivating him to enhance company performance.
