Short

This is a condition resulting from selling an option and not owning the related securities.

Short Sale

Selling stock you don’t own. You hope it drops in price so you can buy it back later at a lower price. You must have a margin account with your broker to sell short.

Short Sale Squeeze

A short sale squeeze occurs when there are many short sale positions on a stock the stock begins to increase. As the stock price rises, the short sellers scramble to cover their short positions, i.e., buying the stock they have sold back. This creates demand for the stock above that which caused the stock price to start rising in the first place, and can lead to rapid price appreciation.

Short Selling

The selling of a security that the seller does not own (naked or uncovered short) or has borrowed (covered short). Short selling is a trading strategy. Short sellers assume the risk that they will be able to buy the stock at a lower price, cover the outstanding short, and realize a profit from the difference.

Reverse Stock Split

This is where a company reduces the number of outstanding shares by decreasing the number of available shares and combining their value into the fewer shares. This has the effect of increasing the stock’s par value. This is often used by companies whose stock is about to be delisted from an exchange because of its low price.

Reverse Takeover (RTO)/Backdoor Listing

A transaction or series of transactions that includes a securities issuance made by a listed issuer to parties vending securities or other assets into the listed issuer (the new security’s holders), such that after completion of the transaction(s), the new security’s holders will own more than 50% of the outstanding voting securities of the listed issuer, with an accompanying change of control of the listed issuer. A reverse takeover (RTO)/backdoor listing can be completed through various transactions, including a business or asset acquisition, an amalgamation, a plan of arrangement, or other form of reorganization. The listing of securities of an issuer formed in accordance with an RTO/backdoor listing is treated as a new listing.

Rights

A temporary privilege that lets shareholders purchase additional shares directly from the issuer at a stated price. The price is usually less than the market price of the common shares on the day the rights are issued. The rights are only valid within a given time period.
