Thanks for the lesson. Much appreciated. I have much better understanding of gross profit and net income now. I have read some of your commentary and I think you may be a person who doesn't like to invest in unprofitable companies. Fair enough it is definitely a safer way to invest. If you ever decide to take a bit more risk and invest in a company that trying to be disruptive could be so bold as to give you a tip.
The big tip is that if you are looking to invest in a company that is unprofitable you need to take a close look at the "unit economics". If the "unit economics" are good you can sleep more comfortable at night. If the "unit economics" are poor you should stay well away from that company. If that company has high debt you could even consider going short that company. I would never do that it is such a dangerous game. Unlimited losses- no thankyou.
You will be glad to know Block's "unit economics" are fantastic. Amrita Block's CFO gave an outline of Blocks "unit economics" on Blocks recent investor day. I have listened 5 times and every time I do I am so happy to be a Block shareholder. You should have a listen. You may even change your view and go long Block. Anyway have a nice day and happy investing. Go Block.
