The news: The turmoil in the US banking sector is proving to be a boon for many short sellers, but their profits may soon come under scrutiny as the Securities and Exchange Commission (SEC) considers a probe into abusive trading practices, per Reuters.
Lucrative short selling: Since the beginning of the banking crisis in March, short sellers have been bagging handsome profits at the expense of failing banks’ stock prices.
Short selling—selling borrowed shares of stock with the intention of buying them back at a lower price—is completely legal. And with a handful of regional bank names in the news each day, it’s not terribly hard to identify which banks investors should bet against.
Strong fundamentals, weak stock prices: The collapses of SVB and Signature Bank were fueled by high interest rates, tanked bond valuations, and bank runs. But something different is happening now with regional banks. The stock prices of banks like PacWest and Western Alliance are plummeting even though they’ve been touting their stable deposits and sufficient liquidity and capital.
This is where short selling gets hairy. Some investors take their bets too far and begin piling on trades in the specific stock to incite volatility and to pressure long-term holders to dump the stock. This drives the stock price down further, earning them a bigger profit.
Regulators are digging in: Calls for an investigation into abusive trading practices are growing, and the SEC appears likely to open a probe into the increase in short selling.
The bottom line: If regional bank stock trading remains volatile, the SEC might determine abusive trading practices by short sellers is the culprit. The agency could put a temporary ban on short selling, as it did during the 2008 financial crisis. But recent research shows that the short-selling ban actually caused those stock prices to fall even further.
In addition to investigating short selling, financial regulators must also consider other factors as potential catalysts for the continuing upheaval, such as rapid communication via social media, incendiary news headlines, and a gap in financial literacy among US consumers.
