When a new era opens, such as railroad bubble

When a new era opens, such as railroad bubble and dot-com bubble, Capex-related stocks rise like crazy in a short period of time and exit after a crash
I think it’s an inevitable event to open that era.
When something innovative is invented, there will inevitably be overinvestment to preempt it, so Capex stocks initially skyrocket. However, when the Capex company takes profits, innovative products become too expensive for consumers to use. If consumers cannot use it, the market itself does not form and the world does not change. No matter how innovative it is, what consumers cannot use doesn’t mean anything.
Eventually, among the companies that were investing in Capex, there are companies that cannot withstand it and step out, and infrastructure providers can no longer take profits, so the greatly inflated expectations go down and collapse.
And at the expense of overinvestment and infrastructure providers, service prices are lowered, increasing public use and changing the world.

Let’s look at the secondary battery crisis that occurred just three years ago. The innovation of electric cars has occurred, and expectations for battery companies have exploded. If the battery companies continued to profit from that expectation, we would never have seen the KRW 49.99 million Model Y now if the stock price had been maintained. Electric vehicle prices are now falling and spreading quickly to the public because battery companies have ultimately sacrificed themselves.

History repeats itself, because everything is designed to do so inevitably.
