its can be dangerous to compare situations that are tenuous at best, but that wont stop me here!, since i have been watching the US market closely there are quite a few examples of wide fluctuations in stocks that in hindsight appear ridiculous or that stretch market credibility,
for eg, (these are massive mkt cap stocks) (SP changes)
NVDA--$326--oh no its business is disintegrating due to bitcoin --(down to) $120---wait now theres AI --(back up to) $470
GOOGL--$150---GOOGL knows nothing about AI--$87---wait maybe they do $140
META--$326--wait AAPl changes, metaverse spend, tik tok--$90----decides to cut costs --$324
these moves were over 18 months, and there are quite a few similar instances.
the point is the SP and mkt cap moves were huge, and clearly overreactions, that gives me some confidence that, at times, the market goes into lala land.....i blame momentum trading
