Peloton is preparing for an IPO. (Initial Public Offering is when a company begins selling stock to the public.) The maker of video-streaming exercise is expected to select its slate of underwriters soon and on track to go public sometimes this year. Peloton is expected to seek a valuation in excess of the roughly $4 billion estimate last year after a fund-raising round led by venture-capital firm TCV. 2019 looks to be a busy year for high-profile IPOs. Uber, Lyft and Slack are also preparing for public offerings. Peloton, founded in 2012, makes stationary bikes that the company sells for prices ranging from $2,245 to nearly $2,700 when packaged with various accessories. Many of Peloton's customers use the bikes at home, paying about $39 a month to stream live classes that the company produces using its own instructors.

Which one of these companies do you think would be a good investment? Why?
