NEW YORK (REUTERS) - Investors betting on declines in United States stocks saw big profits in the last month, as equities crashed while the global spread of coronavirus darkened economic prospects and net increases in short selling imply no turnaround in bearish sentiment.
Short sellers borrow shares and sell them in the hope of buying them back at a cheaper price and pocketing the difference.
US shorts saw a one-month paper profit of US$343.67 billion (S$498.18 billion) from the S&P 500 and Nasdaq's Feb 19 peaks through to March 19, according to the latest data from financial technology and analytics firm S3 Partners, which measures bets against US stocks and American Depository receipts.
The market value of shares sold short dropped to US$656.08 billion on March 19 from US$958.77 billion on Feb 19, including a mark-to-market decline of US$343.67 billion in the shorted stocks and a net increase of US$40.98 billion in short exposure, according to S3.
"Short sellers are topping up their gas tanks ... they continue to have a short bias to the market and they're making sure they're at the levels they want to be at," said S3 managing director Ihor Dusaniwsky.
"At the moment we're seeing active short activity across 80 per cent of the sectors which implies there's still a negative market sentiment," he added.
Sectors that saw the largest increase in short selling were technology services, with a US$3.94 billion increase followed by healthcare services with a US$3.85 billion increase in shares shorted, according to S3.
Companies in the capital markets sector such as brokerages saw short selling increase to the tune of US$3.2 billion while investors increased short exposure to banks by about US$2.6 billion.
That compared with a US$2.5 billion increase for biotechnology.
Industries with the biggest increases in short covering were led by technology hardware, where US$1.4 billion worth of shares sold short were covered, and leisure products, which saw a US$497.8 million increase.
Pharmaceuticals and healthcare technology each saw more than US$200 million increases in short covering.
Microsoft Corp and Apple Inc were the companies with the biggest increase in short covering during the month with US$1.47 billion of Microsoft shares being covered and US$1.39 billion of Apple shares covered.
Since Apple is expected to have manufacturing issues with much of its production in Asia, Mr Dusaniwsky said short sellers may be taking profits in case product deliveries rebound as the China coronavirus outbreak stabilises.
Apple shares fell around 24 per cent between Feb 19 and March 19.
Companies with the biggest increases in short selling were McKesson Corp, Visa Inc, Morgan Stanley, Walt Disney and Comcast Corp.
