All the math we need for trading stocks

A fun math problem suitable for a confident 4th grader

I went to my 9 year old (4th grader)’s class recently and tried to talk about the “The Stock Market Game” (btw, it looks like my main winner is Nike for now 🙂 Below is something I shared in my daughter’s class.

I also tried to answer some questions on individual stocks too, e.g., Adobe, Chipotle, Peabody Energies (do they still have the same name after emerging from bankruptcy, btw).

All the math you need in the stock market you get in the fourth grade.

— Peter Lynch (famous mutual fund manager in the US)

Warren Buffett said something similar (only need 4th-grade math for stocks) in the 2022 Berkshire Hathaway Shareholder meeting, at about 1 hour 40 minutes mark, morning session (available on Apple Podcast and YouTube)

Warren Buffett bought his 1st stock at the age of 11: 1 minute 28 seconds in the video till 2 min 27 sec . I think he is probably in grade 6 or 7 (he may have skipped grade when he was young).

Mutual Fund (this came up as a question and I prepared a bit)

It’s hard to look up Mutual Funds in the Stock Market Game website (app), btw.

VFIAX – VFIAX-Vanguard 500 Index Fund Admiral Shares

I created a notes before I go, and here is the google docs link (you can view it).

PS: 4th grade math on Kahn Academy

(Update 11-10-2023) A coworker recommended the Netflix series below, on personal finance etc. I watched a bit, and I think this is good.

Below is a screenshot, if you are in the free world, you will likely see 2 similar images (to be precise, one is Tweet, the below one is an image)

I think this Netflix documentary series maybe suitable for the kids 4th graders and up 🙂
