What is the uptick rule?

La versione italiana di questa pagina è in preparazione. Fino ad allora il testo è mostrato in inglese.

The uptick rule prohibits placing short sale orders at or below the last price, to prevent short selling from directly pushing prices down.

For example, if the last price is KRW 49,000, a short sale order can be placed only at a price above KRW 49,000. An exception is made for short selling by market makers for market-making purposes.
