Dizzying Valuations, IPO Craze Tick Boxes on Bubble Checklist

The IPO market is manic. Stocks haven’t been this expensive since the dot-com era. The Nasdaq 100 has doubled in two years, leaving its valuation bloated -- all while volatility remains stubbornly high.

It’s a setup that’s left investors sitting on fat returns from 2020, a year that defied easy explanation. It’s also one that has a growing cohort of experts warning about a bubble.

Knowing when market rallies turn from logical to excessive is always tough. It was nearly impossible as 2020 ended, with interest rates pinned near zero and the federal government unleashing another $900 billion into the economy. But history offers clues, and a raft of current market conditions meet criteria that would likely be found on a bubble checklist.

Take a study by Harvard University researchers published in 2019. It noted that while not every stock surge meets with disaster, those that do share some attributes, including increased share issuance, heightened volatility, and a sector or index that doubles and is twice as high as the broader market. Check, check and almost check.

“Are there areas of the market that are in a bubble? Yeah, clearly,” Peter Cecchini, founder of AlphaOmega Advisors LLC, said on Bloomberg’s “What Goes Up” podcast, adding that “many of those are obviously speculative technology companies.”

Share issuance, initial public offerings and blank-check companies have grown so popular that record after record fell in 2020. U.S. companies sold $368 billion in new stock last year, 54% more than the prior high, according to data compiled by Bloomberg.
