The short sell ratio compares specialist activity to the short sales of the whole NYSE. The significance of this measure has declined in recent years due to high-frequency trading (HFT).
Understanding the Specialist Short Sale Ratio
The specialist short sell ratio is a measure of short-sale activity by market makers on the NYSE. These market producers are known as specialists. Every specialist is accused of adjusting approaching buy and sell orders on a portfolio of stocks to work with trading on those shares.
Numerous analysts accept that specialists have a unique point of view on trading activity and consequently improve informed wagers with their own trades. Pundits could answer that, for a long time, NYSE oversight of specialists has been light and point to disciplinary action that the exchange took against a modest bunch of specialist firms in 2003.
In 2003, firms were blamed for mishandling their position to profit from trading activity when they ought to have been going about as neutral facilitators. Electronic trading platforms have progressively displaced specialists on the NYSE and different exchanges. Nonetheless, defenders of the specialist system contend that they give liquidity and oversee volatility such that electronics can't.

High-frequency traders will more often than not cover their short positions rapidly, and have incredibly further developed access to small-cap stocks. This access furnishes traders with a more extensive scope of companies to short. Both of these factors mean that a high-frequency short seller will in general be presented to definitely less risk than a traditional short seller in the past. Less risk prompts all the more short selling, which can distort the significance of the specialists' portion of short interest.
