Individual Stock Breakdown

TSLA | Strongest Yesterday, +1.71%

TSLA was the only one among the four securities to show a clear gain yesterday, strengthening right from the open. Volume of 60 million shares contracted compared to the previous day (74.61 million), but the price action was healthy, closing above 383.
Catalyst: Amazon quietly acquired robotics company Fauna, entering the humanoid robot arena, indirectly proving the strategic value of this sector and boosting market expectations for Tesla's Optimus project. Meanwhile, Tesla's latest leaked robot video showcased a reduction gearbox and dexterous hand design, with technical progress receiving a positive market interpretation.

NVDA | Sideways Consolidation, +0.21%

It barely moved yesterday, with volume of 148 million shares being the lowest of the week, indicating the main players are on the sidelines. The price fluctuated within an extremely narrow range of 174～176, a typical stage of waiting for directional selection.
News: Microsoft and NVIDIA are cooperating to advance nuclear-powered AI data centers. Data from Taiwanese manufacturers showing continued increases in GB200/300 shipments also confirms that computing power demand has not cooled. The short-term stock price lacks new catalysts, but the fundamental narrative remains intact.

ARM | Strongest Intraday High, But Gapped Up and Sold Off

ARM surged to 140.58 (+3.4%) intraday yesterday but failed to hold the gains, eventually closing at 134.96, down -0.77%. However, volume was as high as 11.04 million shares, the second-highest trading day of the week—indicating intense long-short battles.
News:
- ARM officially announced a 2030 revenue target of $25 billion and disclosed that AGI CPUs will enter the Chinese market, providing positive news.
- A concurrent CPU supply chain shortage report shows that Intel/AMD prices will rise by 10%～15% starting in March, with delivery lead times extending to 6 months, increasing the appeal of ARM architecture as an alternative.

Despite failing to hold yesterday's gains, ARM's weekly cumulative gain of +5.1% still makes it the best performer among the four.

Volume Trend (This Week)

Date	TSLA	NVDA	ARM	QQQ
³⁄₁₈	50.85M	157M	4.26M	56.13M
³⁄₁₉	67.08M	171M	3.50M	75.60M
³⁄₂₀	78.63M	241M	12.45M	91.96M
³⁄₂₃	74.61M	183M	7.96M	89.94M
³⁄₂₄	60.00M	148M	11.04M	57.75M

³⁄₂₀ was the week's comprehensive panic day with peak volume across all securities. Since then, overall volume has contracted, with selling pressure gradually exhausting. ARM is the exception—volume remained high on 3/24, directly linked to its news catalysts.

Summary

TSLA was the strongest yesterday, with ongoing robotics sector news providing narrative support. It currently has the greatest short-term elasticity among the four.
NVDA is consolidating without falling, with shrinking volume but stable prices, awaiting confirmation from the next round of computing capital expenditure data.
ARM was the week's contrarian king, with dense news flow, but yesterday's gap-up and sell-off suggests significant short-term profit-taking pressure. The 140 level needs to be digested again.
QQQ continues to see shrinking volume, with overall market selling pressure abating, though the pace of recovery for tech heavyweights remains slow.
