The correct answer is A, Long. When an investor sells shares that they already own in their account, this is referred to as selling a long position or simply a long sale. A long position means the investor previously purchased and owns the securities, so when they sell, they are delivering shares they already possess.
In contrast, a short sale (choice B) occurs when an investor sells shares they do not own, typically borrowing them from a broker-dealer with the intention of buying them back later at a lower price. This is fundamentally different from selling owned shares.
Choice C, Covered, and D, Uncovered, are terms more commonly associated with options trading, not stock transactions. For example, a covered call involves owning the underlying stock while selling call options against it. These terms are not used to describe straightforward stock sales.
Because the investor in this scenario is selling shares already held in her account, the transaction is clearly a long sale, making choice A the correct answer.
