A salesman carries a Best Buy shopping basket in San Francisco, California.

Bank of America Merrill Lynch lowered the firm's rating of Best Buy to neutral from buy on slowing growth and risk to key products.

"We continue to see [Best Buy] as one of the highest quality hardline names but after several years of outsized growth and likely less opportunity for big beat and raise quarters, it is harder to justify," the firm's analyst Curtis Nagle said in a note Tuesday.
