Explanation:
When Anastasia sells her Tesla common stock at the same time that Roman buys the same amount of Tesla stock, then Tesla will receive nothing.
Forur example, let's assume that Anastasia sells her Tesla common stock which was worth $2000 and Roman buys the same amount of Tesla stock, which was $2000. Then Tesla will get: $2000 - $2000 = 0. Therefore, the answer is nothing.
