My understanding is that it was more the 9000 bank failures effectively created a credit crunch. Like if a bank closes and there's no replacement, then most small business were unable to get loans. Farmers who couldn't afford to plant new crops, factories can't improve equipment, inventory get's squeezed across the supply chain, ect. Exports were about 5% of GDP, suggesting that maybe tarrifs may have been the trigger but weren't the primary cause of the depression.
But what if the DJ convinces his audience to invest in a much larger and more expensive night club at an extraordinary premium. Then it might make sense to buy the original night club just to protect the DJ’s scheme.
My math is that Musk’s twitter activity very reasonably increased Tesla’s market cap by more than 5% which is what he is offering to pay.
I mean, 90% of large cap investors have underperformed the sp500. It's not about optimal returns, it's about diversification and portfolio risk. The Saudi's want some of their money in things that aren't correlated with oil, and pretty much everything in the physical word is. Technology is one of the few things that may even be inversely correlated.
