I do agree with the fact that let's say you have a fish tank with so many Big Fish Stocks that only go higher and higher. $AAPL, $AMZN, $MSFT, $GOOG, $FB, $NVDA, $TSLA, $AMD etc etc etc Big Cap Tech's going higher forever and ever until infinity.
When you crowd the Fishbowl Bubble with even more Big Fish like $SNOW.
The food. The "money" to feed all the Bubble Parabolic Prices on Big Cap Tech has to run out.
