Great savings you have there as a poly student! 👏🏼 However, you may want to consider diversifying your investments. Do let me know if you need more info and help. 😊

One good book on stock investments will be The Intelligent Investor by Benjamin Graham. You can read during your free time.

Wow, I think that thought process is a little scary... From what you shared I assume you do not have any investments, just funds in different fixed income accounts?

I think it is wiser to learn more about investing first and speak to a financial advisor about investing. A safer way to start would be via passive investing ... DCA into a broad market index rather than an individual stock that is high volatile in nature. (High beta)
