Introduction
In a recently published research paper, David Duong, CFA, Head of Institutional Research at Coinbase, discusses the concept of short selling in the crypto space. He explains that short selling involves borrowing tokens, selling them at a higher price, and repurchasing them at a decreased price to capture the price difference. Duong highlights the potential benefits of short selling, such as reduced volatility and improved price discovery. However, he also notes that the active market for shorting digital assets is still in its early stages.
Opportunity or Exploitation?
Duong argues that short selling challenges the traditional “buy low, sell high” strategy and allows market participants to identify overvalued assets. He suggests that the lack of a mature short-sale market in digital assets may contribute to historical volatility. Short selling can also be used for hedging, particularly by cryptocurrency miners who face market fluctuations and operational costs.
Disadvantages of Short Selling
While short selling offers potential benefits, Duong acknowledges the inherent risks. Losses can be limitless, especially in the crypto market where tokens can experience exponential growth. He also addresses concerns about short sellers spreading misleading information, although studies suggest that false claims often come from the targeted companies themselves. Despite these risks, Duong believes that short selling can lead to better scrutiny of projects and discourage mismanagement.
Extraordinary Times and Measures
Duong discusses the criticism that short selling can amplify downward price movements during periods of market distress. However, he cites studies indicating that the correlation between short selling and price movements is weak. Short-sale bans imposed during crises may even escalate liquidity costs and volatility.
Proving the Counterfactual
Duong highlights the lack of data on short selling in crypto markets, particularly the absence of a centralized database for major cryptocurrencies like Bitcoin. He mentions the BTCUSD Shorts index, which monitors short positions on the Bitfinex exchange, but notes minimal sensitivity of Bitcoin prices to open short positions. While there was a slightly higher sensitivity during a specific period, Duong concludes that there is no compelling evidence to suggest that short selling significantly impacted Bitcoin prices.
Hot Take
Short selling in the crypto space can offer benefits such as reduced volatility and improved price discovery. However, it also comes with risks, including potential limitless losses and the spread of misleading information. The correlation between short selling and price movements is tenuous, and short-sale bans during crises may escalate volatility. While data on short selling in crypto markets is limited, there is no strong evidence to suggest that it significantly impacts prices.
