This article explores the 20 mid-cap stocks insiders were buying in Q1 2025. Previously, we covered the 20 small-cap stocks insiders were buying in Q1 2025.

Stock markets tumbled on Wednesday, with technology shares leading the slide amid growing concerns over ever-changing tariffs. The broader market index dropped 2.2%, the blue-chip companies fell by almost 700 points, a decline of 1.7%, and the Nasdaq Composite —dominated by tech—plunged nearly 3.1%. With this decline, the Nasdaq is now about 19% below its recent peak, edging closer to bear market territory.

Stocks dropped to their lowest levels of the day Wednesday after Fed Chair Jerome Powell warned that the tariffs could increase short-term inflation. He noted the Federal Reserve might face a tough situation where its goals of full employment and stable prices may come into conflict, according to CNBC.

During periods of market and economic uncertainty, insider trading often draws increased interest. Executive stock purchases can suggest confidence in the company’s outlook, while sales may simply reflect personal financial needs or efforts to diversify investments. Many executives use pre-established trading plans, such as 10b5-1 programs, which are designed to remove timing decisions from the equation. To get a clearer picture, insider activity should be evaluated alongside the company’s overall financial health and broader market conditions.

Our Methodology

Today, we’re focusing on stocks that have seen heavy insider buying activity in the first quarter of the year. Using Insider Monkey’s insider trading screener, we identified companies with market caps between $2 billion and $10 billion, where at least two insiders purchased shares in the past three months. From this list, we ranked the top 20 stocks with the highest value of insider purchases. Most of the stocks that have been recently covered were excluded from our analysis.

Our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds, focusing on insider trading and stock picks from hedge fund investor newsletters and conferences. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 373.4% since May 2014, beating its benchmark by 218 percentage points (see more details here).

For each stock, we note the number of insiders who acquired shares in the first quarter and the market capitalizations. Let’s take a look at the 20 mid-cap stocks insiders were buying in Q1 2025.

20. Arcosa, Inc. (NYSE:ACA)

Market Cap: $3.77 billion

Arcosa provides infrastructure products and solutions for the construction, engineered structures, and transportation markets in the U.S. It operates through three segments: Construction Products (offering aggregates and construction equipment), Engineered Structures (providing utility structures, wind towers, and more), and Transportation Products (offering inland barges and marine equipment).

In March, three insiders, including the company’s CEO, Antonio Carrillo, acquired $618,191 worth of Arcosa shares at an average price of $79.14 per share. Carrillo bought 200 shares, increasing his ownership to 433,283 shares. Currently, the stock trades at $77.17 per share, having lost 20.23% year-to-date. However, over the past 12 months, the stock gained 0.39%.

Arcosa reported fourth-quarter revenue of $666.2 million, a 14% increase from $582.2 million in Q4 2023. For the full year, revenue grew 11%, reaching $2.57 billion compared to $2.31 billion in 2023. The Construction Products segment saw a 31% revenue increase, partly driven by recent acquisitions like Stavola Holding Corp., while organic revenues declined by 4% due to lower freight revenue and the sale of underperforming operations.

For 2025, the company expects revenues between $2.8 billion and $3 billion, with adjusted EBITDA ranging from $545 million to $595 million, reflecting a 30% growth at the midpoint. The guidance includes both organic and inorganic growth, with a slightly higher emphasis on inorganic growth due to nine additional months of Stavola in 2025.

According to MarketBeat, four analysts rate Arcosa stock as “Buy” with a price target of $105.50 per share. This suggests a potential upside of 36.44% from the latest price.
