Answer:
Tabitha's stocks are from a publicly held corporation but Gerald's is from a privately held corporation
Explanation:
The main difference between Tabitha's and Gerald's investment seems to be the fact that Tabitha's stocks are from a publicly held corporation but Gerald's is from a privately held corporation. Public held corporation's stocks/shares can be bought by anyone on a stock exchange. On the other hand Privately held corporation's stocks/shares are only sold by the company to a select few investors. Which Gerald managed to buy solely because it is his brother-in-law's company.
