You'd have lost nearly 20% of your money if you bought these 21 hot tech IPOs of 2014 and 2015

After the manic IPO market in 2014, and the drop off in 2015, the tech market has been all but dead in 2016. Not a single tech CEO took their company public in the first quarter of 2016.

That's expected to change later this week when Dell will spin off its security unit, SecureWorks. But even with that, pickings have been slim.

So we thought it was a good time to look back and see if the frenzy of the past couple of years has been worth it to investors.

We examined the opening stock prices of the 10 hottest tech IPOs of 2014 along with some of the most hyped crop of 2015, and then looked at what they trade for today (mid-day, April 19). (Note, this is the opening retail price, not the offer price sold to institutional investors prior to opening day.)

While a handful of companies are trading above their IPO opening share price, most are not: overall this portfolio is down nearly 19%.
