That doesn’t look like a counterexample to “we formalize the statements by hand and inspect the proofs carefully to ensure they capture the full spirit of the problem”.
I could give you many reasons. I see where you went wrong, here are some to think about:
- next time don't just look at stock value and volume. Look at cashflow
- Consider that most investment volume comes from institutional investors in Wall Street, not in China. Even Chinese investment is routed through NY, Singapore, UK, etc, with the slight exception of Hong Kong.
- Consider geopolitics before investing too. Trump really went all-in in tariffs that basically geofence EV business to american brands.
- The hope for BYD is in EU and UK markets. EU has also been extremely harsh to welcoming BYD and protectionist of their (German) auto makers. This hasn't avoided BYD entering the market, but also has stopped them from shipping en masse. Might change.
- BYD is not a competitor to Tesla. BYD market is the low end market mostly. For example, what today in EU is Dacia (1st or 2nd best seller by number of units). Tesla on the other hand is purposely set up as a mid-high seller. It is too expensive for the cheap segment of the market (10-20k) and is well below luxury vehicles. Different market segment, also better margins in that segment.
- Auto industry is cyclical not defensive. In times of economic uncertainty like today, if you want a solid investment you should look at defensive not cyclical.
- Generally it is a bad idea for retailers to invest in Chinese HQed companies due to the complex geopolitics that surrounding the stock. For example, you have severe limitations in stock market products and they have tight regulation, unlike the US where you have a free-market.
- Consider the market of derivatives. Very different market of futures in China vs the US.
- Tesla is also a self-driving company and robotics company. It would be better compared to XPENG than to BYD.
- Tesla owns the EV market in North America. Period. This is the reality today.
- On top of all that yes the stock is hyped up. But you should know that and invest with that in mind. Being full blown rational in an irrational market will not work.
> - The hope for BYD is in EU and UK markets. EU has also been extremely harsh to welcoming BYD and protectionist of their (German) auto makers. This hasn't avoided BYD entering the market, but also has stopped them from shipping en masse. Might change.
The way this will change is Chinese companies opening factories in the EU. BYD is opening one in Szeged, Hungary soon.
The issue there is the comp. 1.5 euro doesn't make sense. should be O(50). If the compensation (which for DB is a fine in a way) is not high, DB has no incentives to do better.
Good news for you! 1.5 is in O(50) since they’re both constants! (It’s 1.50 because the author has the 58€-a-month flat rate ticket for all local and regional services in the entire country. If you buy a regular ticket, you get back 25% of the ticket price for delays over an hour and 50% for delays over two hours)
it might work, it worked for Thailand. Yet in my experience EU solutions either work very well or fail spectacularly. Particularly when the EU commission is the main driver, they generally become just bureaucratic poodles. However I think this one will work. Yet it will take many years to build (side effect of slow-moving EU) and many more years to adoption. In any case, forget about this for at least 5 years. I do welcome it, but I think it should have happened 15 years ago and I dont understand why it took so long. And I might still be proven wrong and this won't work at all, and yet I wouldn't be surprised. But again this worked for Thailand, so in theory this could be done in EU.
PromptPay use is different from SEPA.
My comment was meant that QR payments are already possible with SEPA in EU it's just there exist different systems built on top of SEPA which are not cross compatible and available across the member states.
My point is, there is a standard for QR payments (I think it's ISO 5201 but it was a long time since I dealt with that). Cross-border support will depend on the country/bank support; but theoretically if everyone adopt it, you'll be able to scan any country QR and then use your wallet to transfer funds (assuming your bank support cross-border payments).
I think ASEAN largely adhere to the standard though the cross-border part is limited to ASEAN.
EU is pro-privatization to the core. Keeping the production of goods and services outside the democratic sphere is arguably the raison d'etre of EU/EEA.
Mind you IBM makes +7B from keeping old school enterprise hooked up on 30 plus year old tech like z/OS and Cobol and their own super outdated stack. their AI division is frankly embarrassing. of course they would say that. IBM is one of the most conservative, anti-progress leaches in the entire tech industry. I am glad they are missing out big time on the AI gold rush. to me if anything this is a green signal.
