Memory Stocks Take the Lead as the Nasdaq and Russell Reach New Highs
US Stocks · Options · News · Views
The first session after the long weekend stayed firm. Of the four major indexes, only the Dow finished lower, while the Nasdaq and Russell 2000 reached fresh closing highs. Risk appetite is continuing to broaden into growth stocks and small- and mid-cap names. Memory was the clear leadership group: Micron jumped about 19%, pushed its market capitalization above $1 trillion, and accounted for more than a third of the S&P 500’s gain.
Oil remained under pressure as investors priced further Middle East de-escalation, with WTI falling toward $96 a barrel and energy becoming the weakest sector. Consumer staples also lagged after cautious commentary from Walmart and Target. This is not a defensive market. Capital is still rotating through technology, memory, industrials, and individual breakout candidates.
The main risk is that valuation anchors in memory and semiconductors are moving too quickly to remain reliable. Micron’s EPS estimates are changing almost like a commodity-cycle forecast: fiscal 2026 consensus EPS is around 58 and fiscal 2027 around 100. Forward P/E can therefore look deceptively cheap while both earnings estimates and the share price are being revised sharply. In this phase, technical levels and position sizing are more useful than a static valuation conclusion.
Energy and basic materials also remain highly sensitive to macro headlines. For XLE, a break above 60.8 would reopen the path toward new highs, while a loss of 55.5 leaves relatively little support before 50 and potentially below 47. Basic materials have a similar setup: above 53.2 is constructive, while a break below 48.7 would weaken the trend. Both groups remain heavily dependent on the Middle East and commodity prices, so headline reversals can produce large moves in either direction.
MU is currently the strongest memory proxy. The 778–813 area has flipped from resistance into intermediate support, and the gap breakout leaves little obvious overhead supply in the near term. Momentum can therefore continue to push the stock higher. The move is already highly speculative, however, so new highs should not be interpreted as low risk. The two key questions are whether EPS estimates keep moving higher and whether the post-gap support zone holds.
TSLA is showing a healthier technical structure. The previous rally failed to break out, but the pullback held the rising trendline and the stock remains well positioned around its 200-day moving average. Daily, weekly, and monthly indicators do not show obvious overbought conditions or major divergence. If capital continues to rotate into the name, a move through 465 could bring 498 and eventually new highs into play. Until the breakout actually occurs, however, the stock is still consolidating rather than beginning a confirmed new trend.
The best approach is to separate leaders from rotation candidates. XLK and REITs are close to new-high structures, so strong names can continue to be managed with the trend. Industrials, supported by data-centre, power-equipment, and hardware demand, have support around 163–167 and a potential breakout zone at 169–177. A decisive move above 177 would confirm further upside. Consumer discretionary depends heavily on TSLA, with 115–118 as strong support and 119–123 as the breakout area.
Defensive sectors require more patience. XLV and XLP still look like low-level consolidations. They may attract capital when investors take profits in higher-risk sectors, but the rotation is likely to be gradual. Financials remain between well-defined support and resistance and are better treated as range-bound in the near term. Across the portfolio, I would keep following strong leaders but use smaller size for late entries. Rotation candidates belong on the watch list first and should be added only after key breakout levels are confirmed.
