We Have an InvestWrite New York State 1st Place Winner!

Long overdue congratulations to Alex C., who as a student in Mr. Plechner's Wall Street class this past spring, participated in the semi-annual InvestWrite essay writing competition. This is a national competition sponsored by the SIFMA Foundation, the sponsor of the Stock Market Game, and involves thousands of students nationally submitting essays. The spring competition required the students to create a well diversified portfolio for a ten year time horizon. Alex identified a number of investments along with supporting analysis as to why he made his selections.

Earlier in the fall, we were notified that Alex was named the NYS 1st Place Winner! This is the third time in five years that our students have taken 1st place in NYS in this competition. Congratulations Alex for an incredibly amazing job well done!
