Quote from vhehn:
According to today's WSJ, "Short-selling activity rose to a new record on the technology-stock-heavy Nasdaq Stock Market, outpacing the rise in bearish bets in other parts of the market."
"For the monthly period ended Oct. 13, the number of short-selling positions not yet closed out at Nasdaq -- so-called short interest -- rose 0.8% to 7,414,701,519 shares from 7,353,774,333 shares in mid-September.
The rise outpaced the 0.1% increase in short interest at the neighboring New York Stock Exchange, which as previously reported also saw its total short interest hit a record in the October period.
Despite a market run-up that has pushed the Dow Jones Industrial Average to records this month, many short-sellers have hung onto their bets, which lose value during such upturns...
The Nasdaq short ratio, or number of days' average volume represented by the outstanding short positions at the exchange, fell to 3.9 from 4.4 last month."
