A Hot Year for IPOs

Beyond Meat has been the most impressive IPO of the year, with its stock up more than 400 percent since the company went public. But it's not the only winner. The Renaissance Capital IPO ETF, a basket of the 60 or so most recent large IPOs, is up 34 percent this year, more than twice the performance of the S&P 500.

Some of the other big names among this year's IPOs include Zoom Video Communications, which is up 176 percent, and  PagerDuty, which is up 109 percent. The internet craft site Pinterest has also done very well, rising 44 percent.

But two of the hottest names in this year's IPO crowd have also been among the most disappointing. The two ride-sharing stocks have both been unimpressive in their debuts: Uber Technologies is down 6 percent, and Lyft is down 19 percent.
