The Alibaba IPO comes amid a lull in an otherwise strong year for IPOs. Will this mega offering fuel the IPO market even further or will it signal mega IPO fatigue?
Jackie Kelley, Global IPO Markets Leader at EY told CNBC: " We have been a little soft, but it's typical for the summer, it's simply pausing for breath."

According to an estimate by Renaissance Capital, the total amount raised in IPOs in the U.S. this year could reach $80 billion from currently $40 billion raised in the U.S. , which would be the highest level since 2000, and almost 50 percent more than in 2013.
And there is still money to be made in IPOs, says EY.
"IPOs typically outperform market, 5-10 percent ahead of our leading indices. Strong fundamentals are definitely driving IPO market activity and great returns for investors."
According to Renaissance Capital, mega IPOs saw a day 1 pop of 11.4 percent and are trading below the IPO price a year later.

Mark Yusko, CIO of Morgan Creek Capital Management, is already an investor in Alibaba - having bought tranches in the private market in 2011, 13 and 14 – and continues to be bullish on the stock.
"We think they have a great management team and that this is a real, legitimate and thriving businesses," he said, which is why he wants to capture the IPO pop.
