Dean Capital Management Reshuffles Portfolio, Trims Astec While Boosting Other Key Holdings

For Astec Industries (ASTE), after selling 61,647 shares, Dean Capital Management held 25,266 shares valued at about $1.095 million in its most recent SEC filing; the article also notes 93.16% of ASTE stock is held by institutional investors.
For Chesapeake Utilities (CPK), Dean’s new position was 27,851 shares worth approximately $3.475 million, and the stock was described as Dean’s 11th largest holding at 1.5% of the portfolio; the article adds company fundamentals including a quick ratio of 0.39, current ratio of 0.43, and beta of 0.69 (market cap $2.89 billion).
For John B. Sanfilippo & Son (JBSS), Dean increased its position by 33.2%, ending with 47,478 shares after buying 11,821 additional shares; the article specifies this represents 1.4% of Dean’s portfolio and makes it the firm’s 13th largest position.
For Safety Insurance Group (SAFT), Dean ended the quarter owning 33,261 shares after adding 26,866 shares; the article says SAFT is about 1.1% of Dean’s portfolio and the firm’s 24th largest holding, and it highlights the scale of other owners—Vanguard Group, for example, held 1,661,343 shares valued at about $129.4 million.
For Prestige Consumer Healthcare (PBH), Dean’s new investment was 40,899 shares valued at approximately $2.523 million, described as its 26th biggest holding; the article also states institutional ownership is 99.95% and notes other major additions such as Norges Bank’s new stake valued at about $36.954 million.
Dean Capital Management slashed its Astec Industries stake by 71%, selling 61,647 shares and cutting its holding to just 25,266 shares worth about $1.095 million, according to MarketBeat. The Kansas-based small-cap value firm simultaneously opened new positions in Chesapeake Utilities and Prestige Consumer Healthcare while dramatically boosting its Safety Insurance stake.
The moves, disclosed in a May 15 SEC filing, reflect a clear pivot away from capital-intensive industrials toward defensive utilities, consumer staples, and healthcare. Dean Capital manages roughly $241 million in assets, according to Fintel.
Dean Capital's exit from Astec Industries was steep. The firm sold more than 61,000 shares, reducing a position it once held more than four times larger. Institutional investors still own 93.16% of Astec stock, according to MarketBeat. Other large firms moved in different directions — AQR Capital Management previously initiated a new stake of 108,751 shares, while Royal Bank of Canada also adjusted its position.
The valuation math may explain Dean's exit. Simply Wall St notes Astec trades at a price-to-earnings ratio of 44.8 times earnings — well above the US machinery industry average of 26.7 times. Still, Freedom Broker kept a $66 price target on the stock in April 2026, citing multi-year federal infrastructure spending as a catalyst, according to Insider Monkey.
Dean opened a brand-new position in Chesapeake Utilities, buying 27,851 shares worth approximately $3.475 million. The stake instantly became the firm's 11th largest holding at 1.5% of its portfolio, according to MarketBeat. Chesapeake carries a market cap of $2.89 billion and a low beta of 0.69 — a sign of stability compared to industrials.
CEO Jeff Householder raised Chesapeake's dividend by 7.3% in May 2026 — the company's 65th consecutive year of uninterrupted payments. On Safety Insurance, Dean added 26,866 shares, a 423% surge, bringing its total to 33,261 shares. That position is now the firm's 24th largest holding at 1.1% of assets. For comparison, Vanguard Group holds 1,661,343 Safety Insurance shares valued at about $129.4 million, per MarketBeat.
Dean also added 11,821 shares of John B. Sanfilippo & Son, a nut and snack company, growing its position by 33.2% to 47,478 total shares. The holding now sits at 1.4% of Dean's portfolio and ranks as its 13th largest position, according to MarketBeat. Sanfilippo reported mixed Q3 2026 earnings in late April, prompting renewed institutional scrutiny.
Dean's newest consumer healthcare bet is Prestige Consumer Healthcare. The firm bought 40,899 shares worth about $2.523 million, making it Dean's 26th largest holding. Institutional investors own a remarkable 99.95% of the stock, according to MarketBeat. Norges Bank separately initiated a $36.95 million position in the same period.
That near-total institutional grip creates risk. If major holders exit at the same time, few non-institutional buyers exist to absorb the selling. Simply Wall St estimates the stock may be up to 30.1% undervalued after a 25.1% price drop over 90 days and a guidance miss in fiscal 2026 — but any recovery depends on margin improvement that has yet to materialize.
