Core analysis of the stocks you mentioned

FLEX Flex Ltd.

As a core contractor in AI infrastructure, its stock price has risen 117.6% in the past six months. Recently confirmed for inclusion in the S&P 500 index (effective June), it will benefit from passive capital inflows. Currently, 40% of its business is related to AI servers and the telecom equipment supply chain, with strong earnings certainty. PE of 64.2 is high but reasonable compared to pure AI chip stocks. Beta is only 0.87, less volatile than major tech stocks, suitable for long-term holding.

GEV GE Vernova

A global leader in power infrastructure, directly benefiting from the AI data center power demand surge. It has risen 43.9% this year. PE of 27.5 is among the lowest of your mentioned stocks, PEG only 0.17, with very strong earnings growth certainty. As a utility-like tech stock with counter-cyclical business properties, its long-term logic of growing power demand remains unaffected by AI cycles, making it an excellent "ballast" stock in the portfolio.

AVGO Broadcom

Core supplier of AI chips and optical modules. Current valuation already reflects prior overly high expectations: forward PE based on June 12, 2026 estimates is just 19.74, much lower than previous highs. Recent 13% stock correction is mainly a short-term market reaction to gross margin guidance, but the long-term demand for AI chips and switch chips remains unchanged. Analyst consensus target price still has about 30% upside, making it one of the most certain semiconductor stocks.

EUV ETF

This ETF tracks the EUV lithography and semiconductor photonics industry chain, holding ASML, related materials, and equipment companies. It's a tool for diversified investment in the semiconductor upstream sector. However, its current liquidity is low (average daily volume under 1 million shares), and volatility can be higher than individual stocks; suitable for small position allocation.

Google (GOOGL)

Current PE (TTM) is 28.69, at the 95th percentile of its historical valuation range, indicating some valuation premium. Not recommended to use 2x leverage:

1. Two times leverage amplifies volatility; even if it goes up long term, a 15% drawdown means a 30% loss, which doesn't align with your desire to "sleep well at night";
2. Google's cloud and AI search growth have high certainty but are volatile, already down 10% in the past month; leverage greatly increases your position risk. If optimistic about Google, directly hold the stock for higher long-term certainty and avoid leverage costs and volatility risk.
