What's your take on retail investors and active investing, assuming that the retail investor does not have access to large sums of money.
I think it's worth working out the math for yourself, rather than taking anyone's words for granted. Let's say the average annualized return of S&P500 is 10% (obviously, past returns are no guarantees of future returns). If you buy and hold, then you essentially pay no taxes on your capital gains.
Let's suppose the alternative is to actively trade, and your strategy involves holding securities < 1 year, incurring the maximum short term capital gains of 37%. Let's say your strategy generates an annualized average return of 20%, pre-tax.
So the annualized net worth (after capital gains taxes) starting from $100 would be:
passive: 100, 110, 121, 133
active: 100, 112, 126, 141
So you can generate 10% excess returns, after taxes you compound approximately 2% additional take-home money each year. Then you should ask yourself, is it worth the hassle? Maybe it is. Maybe it isn't. Some people enjoy researching companies, making predictions, and allocating capital to their beliefs.
obviously, there are ways to try and mitigate capital gains taxes - incorporating offshore LLCs, tax loss harvesting, etc. those are important considerations when designing an active trading strategy.
Separately from whether active investing is worth it or not, I think it's valuable to learn how to read financial reports and understand businesses as a projected set of cash flows, along with understanding things like balance sheets and incomes. Learning to read 10-Qs has helped me think of my own budget / personal finance planning much like a business. Financial literacy is super important, even if you are a passive investor.
The comments by Martin Shkreli I was referring to are actually in the video that you linked. The subtlety in Shkreli's comment is that he was referring to amassing "fortunes". That is where he states that amassing fortunes most likely requires using "other people's money". Which makes sense.
He cites Joe Lewis as an example of a solo investor going from "zero to hero", but I would not say he was strictly an "investor" as he was a currency trader. Also, he had initial wealth from a luxury goods business.
Just for curiosities sake, do you know of any examples of retail investors amassing sizable amount of money starting from very little?
I agree with Shkreli: if you want to "amass a fortune in a short amount of time" AND do so without taking on an unreasonable level of risk, then doing so with cheap cost-of-capital (e.g. investing friends&family wealth, using insurance float, gift cards) is the way to go.
But "making 10s of millions quickly" is a different statement than "active trading is not worth the effort".
If you don't have time for the full course, I've also heard good things about Damodaran's Little Book of Valuation.
If you check out the email archives [1], you'll see that Damodaran wrote this in the first message: "1. Preclass work: I know that some of you are worried about the class but relax!
