Last week, major U.S. indexes witnessed their worst performance since the start of the conflict in the Middle East. The Nasdaq Composite, the S&P 500, and the Dow Jones Industrial Average fell 4.5%, 3.2%, and 2.3%, respectively, marking the fifth consecutive week of losses. High volatility and a sharp sell-off began as the ceasefire proposal by the United States was rejected by Iran. Market participants are now pricing in a sustained conflict, leading to fears of long-term disruption in the Persian Gulf.
Crude oil prices touched $100 per barrel. This spike has intensified concerns about "stagflation," a period of slowing economic growth paired with high inflation. Economic data painted a picture of a "low hire/low fire" labor market. While initial jobless claims remained steady at 210,000, actual job growth has been sluggish. Productivity for the fourth quarter of 2025 slowed to 1.8%, while unit labor costs jumped to 4.4%, the highest level in a year.
The housing market weakened, with mortgage applications down 10.5% as 30-year rates hit a year-to-date high of 6.43%. Meanwhile, consumer sentiment dropped to 53.3 in March from 56.6 in February, the lowest since last December. Investors remain cautious, weighing the stability of the economy against rising fuel and transportation costs.
Regardless of market conditions, we, here at Zacks, provide investors with unbiased guidance on how to beat the market.
As usual, Zacks Research guided investors over the past three months with its time-tested methodologies. Given the prevailing market uncertainty, you may want to look at our feats to prepare better for your next action.
Here are some of our key achievements:
Sandisk and Equinix Following Zacks Rank Upgrade
Shares of Sandisk Corporation SNDK have gained 30% (versus the S&P 500’s 8% decrease) since it was upgraded to a Zacks Rank #1 (Strong Buy) on Jan. 26.
Another stock, Equinix, Inc. EQIX, which was upgraded to a Zacks Rank #2 (Buy) on Jan. 28, has returned 19% (versus the S&P 500’s 8.8% decrease) since then.
Zacks Rank, our short-term rating system, has earnings estimate revisions at its core. Empirical research shows a strong correlation between trends in earnings estimate revisions and near-term stock price movements.
An equal-weight portfolio of Zacks Rank # 1 stocks outperformed the equal-weight S&P 500 index by 7.7 percentage points in the year-to-date 2026 period (through March 3, 2026); The Zacks Rank #1 stocks returned +6.57% through March 3, while the equal-weight S&P 500 index lost -1.14% of its value.
In 2025, this hypothetical equal-weight portfolio returned +17.81% vs. +10.85% for the index, while performance comparison was +22.4% vs. +13.7% in 2024. Over the preceding 10-year period (2016 through 2025), this portfolio of qual-weight Zacks Rank #1 stocks outperformed the equal-weight S&P 500 index by more than 7 percentage points (+18.55% vs. +11.65%).

Zacks Recommendation Upgrades Modine Manufacturing and Archrock
Shares of Modine Manufacturing Company MOD and Archrock, Inc. AROC have advanced 21.1% (versus the S&P 500’s 8.6% decrease) and 20.4% (versus the S&P 500’s 8.8% decrease) since their Zacks Recommendation was upgraded to Outperform on Jan. 30 and Feb. 3, respectively.
While the Zacks Rank is our short-term rating system that is most effective over the one- to three-month holding horizon, the Zacks Recommendation aims to predict performance over the next 6 to 12 months. However, just like the Zacks Rank, the foundation for the Zacks Recommendation is trends in earnings estimate revisions.
The Zacks Recommendation classifies stocks into three groups — Outperform, Neutral and Underperform. While these recommendations are determined quantitatively, our analysts have the flexibility to override them for the 1100+ stocks they closely follow based on their better judgment of factors such as valuation, industry conditions and management effectiveness than the quantitative model.
