In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool analysts Jason Moser and Brendan Mathews take a question from a reader who writes, "I am putting my tax maximum into my IRA, and I wondered if y'all have some ideas for an aggressive portfolio. One of the stocks I have been looking at is Seadrill (NYSE:SDRL)."

In terms of aggressive stocks for growth, Brendan likes (NASDAQ:BKNG) because of its lucrative business and potential for growth in the online travel business. Of course, there is some disruption risk from Google (NASDAQ:GOOGL) (NASDAQ:GOOG) or TripAdvisor (NASDAQ:TRIP).

Jason likes (NASDAQ:AMZN), particularly given its pullback in share price. The company still has plenty of room to grow in ecommerce, and investors shouldn't forget about the potential of Amazon Web Services. Brendan finishes with a final idea, which is WisdomTree Investments (NASDAQ:WETF). The company has huge potential to grow in the ETF market.
