Most comparisons compare things you cannot use
Search which of these two suits a beginner and what comes back compares constituents, ten-year returns, volatility, and which is better to hold long term.
None of that is false. But for someone who intends to trade, it answers “which one do I buy and hold”, not “when do I sit down and read the chart”.
Holding long term and trading are two different things. The first compares the instrument. The second compares whether your hours and the market's line up.
So this piece compares one thing only: which stretches of time you can actually find in a week, and which index is suited to trading in them.
