The upcoming Snap IPO isn't the only reason for investors to be excited.

The year 2017 is shaping up to be a comeback time for initial public offerings, according to Kathleen Smith, chairman of Renaissance Capital. Smith notes the Renaissance IPO index is up more than 30% over the past year, outperforming the S&P 500.

Smith said there's a long list of potential tech IPOs that could go public this year, including Uber and Airbnb. She added that it's not just technology company IPOs that look promising, as there's been a lot of activity in industrial and energy offerings.
