Construction Giant MasTec Leads 11 Newcomers To Best Stock Lists, Defies Market Correction

IBD stock screens are regularly updated to add new stocks to watch, as well as weed out those that have started to show weakness. In the tables below, you’ll see which stocks like MasTec (MTZ) have been added to or removed from lists like the IBD 50 and Stock Spotlight list.

On a day when the Dow Jones fell more than 700 points, one might think it unusual to find stocks hitting a record high and seeing big gains. But 11 stocks qualified for best stock lists Wednesday, including construction firm MasTec and energy play Rex American Resources (REX). Both hit an all-time intraday high then pulled back amid the market bloodletting.

Other stocks had strong gains despite the market. Chipmaker and AI stock Lattice Semiconductor (LSCC) rose 2% for the day. Meanwhile, energy stocks Cenovus Energy (CVE) and Okeanis Eco Tankers (ECO) rose 1.6% and 1.7%, respectively as the Iran war drives up oil and natural gas prices.

The screens are based on The IBD Methodology, which looks for stocks displaying the common traits typically shared by the best-performing stocks in the early stages of their big price moves. Check this column each day to help build and maintain your list of stocks to watch with alerts to the most recent changes.

Construction Giant MasTec Pops To All-Time High

MasTec is a group of construction companies. They provide building, installation and maintenance of communications, energy and other infrastructure projects. The company says on its website that its 22,000 employees “have been involved in some of the largest and most complex infrastructure construction projects across the country.” MTZ stock rose to an all-time high 310.64 Wednesday as the company benefits from traditional construction projects as well as the proliferation of massive AI data centers.

But never buy a stock just because it’s on an IBD list. Be sure to do your own research and run all your stock ideas through a buying checklist. And you can use IBD’s simple three-step routine to quickly track general market trends, find stocks to watch, and pinpoint the best time to buy and sell.
