Those looking to short the US markets at some point might want to look into shorting either the NASDAQ index by looking at SNAS (ASX) or looking at one of the single company or sector leveraged short etfs that trade on the LSE.

For example the following leveraged short Apple ETFs trade on the LSE:
AAPS (LSE)
3SAP (LSE)

Both are x3 leveraged short positions on Apple.

If you look at US markets by sectors and by cap sizes, it's only the magnificent 7 tech stocks that are flying. Small caps are down. Most resource stocks (gold, copper miners especially) are down. Industrials are down. Stocks markets have not been in a rising tide lifts all boats rally. The magnificent 7 tech stocks are swimming against the tide.

Also, I think that consumer discretionary is actually going to hold up well in Australia and the USA because of the swelling cohort of retirees who don't carry debt and who have stable retirement incomes and who are going to consume services (travel, hospitality) regardless of interest rates.

I could be wrong but I think there is a chance of a sector rotation away from tech at some point.
