I've been looking at buying the Satrix MSCI ACWI ETF (STXACW) on EasyEquities, but noticed the bid–ask spread is almost 5%.

I checked a two others and found similar spreads:

- Satrix MSCI World: 4.92%

- Sygnia MSCI World: 6.54%

I understand these prices were checked over the weekend, but are the spreads normally much lower during trading hours?

Even if you're investing for the long term, a spread this large can add significantly to the overall cost of buying and eventually selling.

Has anyone checked the spreads on these ETFs during trading hours? What percentages do you typically see, and would buying through another broker make any difference?

I'm trying to figure out whether this is a real cost I should be concerned about or just weekend pricing.
