Short Selling – The Good, The Bad and the Ugly

The Idea of Short Selling

“Buy Low, Sell High”, a commonly heard strategy based on taking advantage of the appreciation / depreciation in price of the underlying asset. Let’s take it a notch up, and review a strategy that functions on the fall in price of the underlying asset, “Selling High first, Buying Back Low”. Are you familiar with this trading strategy?

The idea of short selling is to borrow the underlying asset, sell it and buy the underlying asset in the future at a lower price to return it, benefitting from the difference in the selling price and buying price [1]. The maximum potential profit of a short position is 100% (when the underlying asset goes to a price of $0). However, the maximum potential loss is infinite as there is no upper cap to limit how high the underlying asset price can go.

Legendary Short Sellers & Stigma

Many consider short selling a taboo.

In 2008, the Securities and Exchange Commission (SEC) reactively enforced 2 temporary riles to constrain short sellers who were blamed for some of the patterns in the stock price movements during the financial crisis that began in March that year. As the market deteriorated that year, short sellers were blasted for thriving while everyone else was at its wit’s end. Short sellers benefit from the collapse in the prices of the underlying, ranging from a company’s stock price to a nation’s currency.

For example, the most Legendary Currency Short Seller George Soros, also known as “The man who broke the Bank of England”, raked in $1 billion pounds in profits by shorting the British Pound heavily, forcing the British Government to withdraw from the ERM (European Exchange Rate Mechanism) [2]. The chart below shows the magnitude of the drop of GBP/USD between late 1992 till early 1993.

From 1997 to late 1998, Asian countries like Thailand, Indonesia and South Korea were hit badly by hedge funds led by George Soros’s Quantum Fund, Julian Robertson’s Tiger Fund and other hedge funds that joined the speculation [3]. At first , the Bank of Thailand (Central Bank of Thailand) attempted to stabilise its currency (Baht) by using a foreign currency like the US dollar to purchase Baht in the foreign exchange market. This would have increased the value of the Baht artificially by causing an increased demand. Furthermore, this would have increased interest rates for the Baht and restricted foreigners’ access to the Baht to fight speculators. In the short run, this strategy pumped the value of Baht up. However, as the Bank of Thailand’s foreign reserves dried up, it attracted more hedge funds and speculators to short the Thai Baht even more. Without foreign reserves to defend the Thai Baht, the bank devalued the currency while the hedge funds profited, leaving Thailand in a currency and financial crisis. This signalled the start of the Asian Financial Crisis, which spread to other emerging Asian markets around the region.

Importance of short selling

Even though short selling benefits from the drop in the underlying price, it is necessary for more efficient price discovery. Short selling allows downward pressure from sellers to be represented in price discovery as it is one of the key functions of a market. Buyers and sellers can influence the underlying price to better reflect their view on the fundamental price. This is compared to markets that ban short selling, so that only the buy side influences the price, causing the underlying price to be skewed and biased. It is shown that in markets that allow short selling, asset prices are closer to their fundamental value compared to exchanges that do not allow short selling [4].

Furthermore, short sellers are incentivised to identify malpractice and fraud in companies, engaging in due diligence, auditing and investigative work, identifying companies that are defrauding investors and customers such as Enron, Wirecard AG and Valeant just to name a few [6].

While overall markets were obsessed with Wirecard and wanted a piece of it, Safkhet Capital (a short-only fund) found that it (Wirecard) was actually indulging in illegal practices and deciding to short their stock. However, regulators such as BaFin did not look into the allegations of illegal practices in Wirecard. Instead, they went after the short sellers for possible market manipulation; they even went to the extent of banning short-selling in Wirecard entirely [7].

These are regular occurrences in hedge funds for short-sell as well as major short-selling players, as they face criticism and are blamed for crashes and the failure of companies. However, without short sellers revealing fraudulent businesses, they would be akin to parasites to the market, causing more harm to the investing community in the long-run.

Strategies that short sellers utilise

Hedge funds that specialise in short-selling do their fundamental analysis to determine if the underlying company is overvalued. The hedge fund will then publicly announce their short position and publish a short report stating their underlying reason for going short [9]. The short report will cover the bearish outlook and any negative aspect of the company in an attempt to convince other market participants to sell their shares, or go short as well to push prices down to the fundamental price that the hedge fund desires. This is a more public approach as hedge funds are not required to disclose short positions in their quarterly filings. Therefore, publicly announcing their short positions and publishing the short report can help push prices down, but can also cause the hedge fund to be the target of a short squeeze.

Strategies against short sellers

A short squeeze is a strategy that aims to put pressure and ultimately force the short seller to cover his position by increasing the price of the shorted company’s shares. As short positions are generally traded on margin, a significant increase in the share price will cause the short-seller to get a margin call forcing him to cover his short position by buying back shares in the open market, further pushing prices up even more. A short squeeze on illiquid counters that have a large amount of short interest can cause the system to collapse.

The best example for this is the short squeeze on GameStop in January 2021, where the short interest for the GameStop stock was at a record 140% of the total public float. Individual investors and some hedge funds decided to short squeeze the short sellers of GameStop by purchasing and pushing the price up, resulting in an explosion in stock price from $17 USD (at the start of the month) to a pre-market price of over $500 USD [10]. This is seen in the graph below.

This shows the risk of using short sell as a strategy, namely the risk of being short squeezed and being forced to close the trade at a loss.
