1. Commodities are bad long term bets because technology gets better. I remember people talking my ear off about peak oil and then the US turned into a net-exporter. Short term inelasticity, yes can sky rocket prices; but long term prices go down.
2. Physics based thinking. I knew electric cars were going to work because the math checked out.
3. Economics of scale works. Find companies that understand this and focus on it. When I saw Telsa focussing on a single car for a year I knew they would be a winner.
4. Software scales. People like to make money. Combine the two and its a real winner.
5. Sell when forward price to earnings after cash starts to look wonky. Which was 2007 and I think 2019. Covid and the direct stimulus kinda messed up the timing, but the market is still completely screwed. Either way, sell early and buy the crash.
Telsa, Apple, Shopify, Amazon, Google. Only really lost on Etsy (I can't believe how much they missed the opportunity to become a real platform).
Why bother investing in GM through a broad index fund if I know for sure Tesla will eat their lunch?
This isn't really get-rich-quick. This is looking at companies rationally and projecting where they will be in a year or two. And rationally speaking this market is out of wack and I wouldn't advise investing in even my favourite tech companies right now. I don't think this is Japanese Tech level of readjustment. I think there will be a -%50 S&P500 crash, maybe more, and then in 10 years Apple will be worth more than double what it is worth today. They have fundamentally better technology. Their software competency is below average, but their hardware, fit and finish, design, and cultural cache is world class and it is hard for me to imagine any scenario where they lose other than a US war with China.
