What if he wins? A common thread among gambling addicts is a large win at a young age. It’s not that unlikely that he will beat the market during his most formative years and you will have taught him the opposite of what you intended.

He's still a kid and he could only invest under my supervision. It is a small amount of money and he is not going on the margin. If he kept doing great year over year I would let him keep going.

Here's what really happened: He bought a bunch of kooky stocks because he "liked the name". That did predictably terribly. Then he bought a couple blue chip companies, lost interest and drifted into the black. If you buy individual stocks and hold them, on average you will make money. You would usually do better with an ETF too. I think it was a good lesson that patience is better than trying to outsmart markets.

I can't speak for others but I can share one anecdotal experience by sharing my story.

I started investing in middle school when the social studies teacher enrolled all of his classrooms into a virtual stock market simulation. Everyone starts with 100k, must own a minimum of 20 stocks on any given day, and tries to make the most within a set amount of weeks. Short-selling is included. I don't remember how well I did but I got an ornate Dominos Pizza gift certificate (which I never spent because it looked so beautiful) so I must have done well. That was 13 years ago. Today, I have a 40k Robinhood investment account which is enough for a home down payment and I plan to use it to buy a modest ~200k home in a few months.

I outperformed significantly in my early 3 years of investing with real money with a 38% return. However I have underperformed in the last 1 year and thus underperformed the market overall with an 18% overall (4-year) return not including dividends. This is because my favorite investment data app, StockGuru Pro, that cost $10 was discontinued and I don't have a suitable replacement (at all). I expect to underperform in the future unless I find a well-priced replacement or cough up the hundreds of dollars for better investment data. The ICE buyout of the NYSE has caused the price of market data to skyrocket which lead to that app's discontinuation.

The wins I experienced at a young age were very positive because it gave me a reason to save my money instead of spending it on all the things I wanted. Savings account interest rates of 0.01 to 2% interest isn't motivating at all to save because it takes more than 36 years to double money at that rate. If it weren't for learning to invest at an early age, I'd be just like the rest of the average Americans. The 50th percentile for my age (27) has a net worth of $5000 and I would be average with $5000 too if I didn't have that reason to save!

It also provided a good learning experience from which I have formed 5 principles:

1) Take calculated risks

2) Protect your principal but it's okay to risk the interest. (Phrased another way: don't lose money.)

3) Don't put all of your eggs into one basket. Diversify!

4) Don't use margin if you don't know what a margin call is.

5) Options are for viewing, watching, and analysing but not for trading (even if Robinhood makes trading them free). 90% of people lose money trading options.

Overall, an anecdotal positive experience here that I'm happy to share but with a small sample size of one.
