Take the Zacks Approach to Beat the Markets: Mirion Technologies, Avino Silver & Gold Mines, Quanta Services in Focus

Read MoreHide Full Article

Key Takeaways

  • Mirion Technologies shares have surged 42.8% since a Zacks Rank upgrade on April 16.
  • Avino Silver & Gold Mines jumped 81.6% after a Zacks Recommendation upgrade on April 22.
  • Quanta Services rose 37.4% in 12 weeks as a Zacks Focus List stock despite broader market losses.

Last week, the three most widely followed U.S. indexes — the Dow Jones Industrial Average, the Nasdaq Composite, and the S&P 500 — suffered losses of 1.32%, 0.94% and 0.48%, respectively. Escalating geopolitical tensions in the Middle East between Israel and Iran have sparked fear among investors. Additionally, trade policy uncertainty, along with the impact of tariffs on future prices, remains a significant factor influencing the economic outlook.  Lower-than-expected inflation and a cooling labor market provided some optimism.

Both the Consumer Price Index (CPI) and Producer Price Index (PPI) have shown progress toward achieving the Fed's 2.0% inflation target. CPI and PPI have both increased by 0.1% for the month of May. On a year-on-year basis, the CPI rose by 2.4%, whereas the PPI advanced 2.6% last month after rising 2.3% and 2.5%, respectively, in April. The significant escalation of geopolitical tensions in the Middle East, particularly due to airstrikes between Israel and Iran, has led to a sharp surge in oil prices, raising concerns about potential inflationary pressures down the line. The U.S. labor market added 139,000 jobs in May, down from 193,000 a year ago. The unemployment rate held steady at 248,000, and wage growth was 3.9% year over year.

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.

Zacks Recommendation Upgrades Avino Silver & Gold and Comfort Systems USA

Shares of Avino Silver & Gold Mines Ltd. (ASM - Free Report) and Comfort Systems USA, Inc. (FIX - Free Report) have advanced 81.6% (versus the S&P 500’s 16.2% increase) and 38.5% (versus the S&P 500’s 11.5% increase) since their Zacks Recommendation was upgraded to Outperform on April 22 and April 24, 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.
