Which US and UK ETFs should I consider for either dividends or growth?

My top picks are QQQ or QQQJ. I personally think QQQJ is one to watch for even longer term growth. At some point, FAANG stocks will stop leading the market and a new batch of companies will step up. QQQJ offers exposure to these potential leaders of the next decade.

For dividends, my preference is still with Singapore Reits. Check out Syfe REIT+ for an alternative to REIT ETFs!

For simple investing for growth, the S&P 500 (or more aggressively, the NASDAQ 100) has proven themselves to be solid investments, provided you have a long time horizon. Alternatively Global indices do provide respectable growth as well, diversifying your money further around the world as opposed the US Indices.

US based:

S&P 500: VOO/IVV (they're virtually the same thing)

NASDAQ 100: QQQ

Global ex US: VXUS/ VEU

UK Based:

S&P 500: CSPX/VUSA

Global: IWDA/VWRA

For dividends I wouldn't advise US or UK ETFs as both are subjected to withholding tax on dividends (15% in the UK and 30% in the US). As such, if you're seeking dividends, many local companies do provide good dividend options. Our REITs alone provide quite the selection with many yielding 3-5% depending on where you look. However, if you're young, a growth style investment will likely yield higher returns as dividends often work much better with a large capital.
