Short Interest in Nasdaq Isn’t Rising
By Phil Mackintosh, Chief Economist, Nasdaq
A recent article showed that Nasdaq short interest was at all-time highs, suggesting that “bets against the Nasdaq reached their highest point in a decade.”
But that is only true if you count shares shorted. Once one accounts for shares outstanding, you find that the short interest ratio is actually falling. That’s not nearly as bearish a signal as some headlines indicate.
Total shares shorted have tracked the index higher
As the Nasdaq Composite has rallied over the past decade, total shares shorted have mostly tracked in step. Initially that makes it look as if the market has become “richer,” with hedge funds making increasingly bearish bets on the Nasdaq.

But understanding the market is not that simple. We recently highlighted that there are other reasons to shortstocks, like hedging futures and options interest or expanding statistical arbitrage strategies.
But our issuer base has also grown
Three areas of growth account for an increase in shares outstanding which more than accounts for the increase in shorted shares. Those three factors adding to our listed company share count are:
- IPOs: Looking at our own data, since 2011 Nasdaq has brought more than 1,380 new companies to market via IPOs, representing 64% of all new U.S. listings.

- Switches: It turns out Nasdaq has won 76% of all switches among U.S. equity exchanges since 2005. Some of the household names that switched to Nasdaq include PepsiCo, Sanofi, T-Mobile, Kraft Foods, Walgreens Boots Alliance, Exelon, Workday, and recently announced AstraZeneca and Keurig Dr. Pepper. That adds to almost $1 trillion in additional market cap before appreciation.

- Splits: There have also been a few (although not a lot) splits. That also increases the shares available, and the short interest totals, without actually increasing the short interest ratio.
IPOs, switches and splits more than account for the increase in short shares
When we account for all the new shares that IPO’s, Switches, splits, it turns out they have account for 3.5 billion shares of short interest. That’s more than the 3 billion additional short shares in the first chart.

The short interest ratio in the Nasdaq is actually falling
In fact over the past five years our short interest ratio, short interest as a proportion of shares outstanding, has fallen from 4.25% to around 3.75%.
Chart 5: The short interest ratio is actually declining
Amazingly that’s the opposite of the initial headline, which proclaimed “bearish bets against the Nasdaq were at decade highs.” Actually the proportion of bearish bets has been falling recently, and is actually near decade lows.
There is a reason why finance often uses ratios, like the price-earnings and dividend-yield and short-interest ratios. They allow you to better compare one stock, or market, to another as other things change over time.
