> Which market? The stock market? Or the tech stocks?

Both.

Across the entire stock market, not a ton of bright spots _except_ for Tech.

Then someone says the market; they definitely mean the stock market. I don't know what else you can understand from it.

Why would the entire market implode?

Because in 2008, the housing bubble popped and it dragged with it the entire stock market. Stocks are more interdependent than most people realize.

Because tech is 1/3 of the US stock market?
