Enterprise Products Partners (EPD) was Smart Insider's stock pick of the week after the company's non-executive John Rutherford purchased $470,000 worth of company shares at $31.35 apiece on July 29, raising his ownership by 10%.

Rutherford has a "good record" in the stock purchase, and waited until 2020 to make his first buy at $19.22 per share before subsequently making a series of purchases into rising prices, Smart Insider said in a Tuesday note.

This was Rutherford's second largest stock purchase and the highest price he has paid, the note said, adding that it is "notable that he's now buying in larger-than-average size at this higher price."

Smart Insider ranked the stock +1, or strong positive signal, on July 30.
