Vulcan Materials is sliding today, mirroring a broader downturn across the construction materials industry as peers like Martin Marietta Materials and United Rentals also face downward pressure. This move coincides with a wider market retreat on September 1st, where investors have pulled back from equities amid rising oil prices and concerns regarding inflation and geopolitical instability. While recent filings show Quantitative Investment Management LLC established a new stake in the company during the second quarter, this institutional activity has been unable to insulate the stock from the current sector-wide selloff.
