Lamb Weston Holdings (LW) was Smart Insider's stock pick of the week after the company's Director Robert Niblock bought $183,000 worth of Lamb Weston's shares at $60.94 apiece on Jan. 13, increasing his ownership by 13%.

Chair William Jurgensen and Director Charles Blixt purchased $316,000 and $76,000, respectively, worth of the company's shares at roughly $63.25 apiece on Dec. 23, Smart Insider said in a note Tuesday.

This was Blixt's first share purchase, the note added.

"We ranked the stock +N in July 2024 based on purchases from Niblock and Jurgensen, and the signal proved timely with a 30% return over three months. The stock has since declined, and it is interesting to see both directors make additional purchases," according to the note.

Smart Insider ranked the stock +N, or notable and positive signal, on Jan. 15.
