S&P 500 Equal Weight
Equal-weighted US large-cap equities
Overall verdict
MSCI World answers a geographic question: how much of the developed world should the portfolio own. S&P 500 Equal Weight answers a weighting question inside a single market: should the largest US companies dominate the result. They are not substitutes, because moving from MSCI World to S&P 500 Equal Weight simultaneously removes non-US markets and removes cap weighting.
Quick Decision
Choose MSCI World if…
the portfolio needs developed-market breadth first, and you accept that US mega caps will be the largest positions because they are the largest companies.
Choose S&P 500 Equal Weight if…
you have already decided on US large-cap exposure and want the outcome driven by the average constituent rather than by the biggest handful.
Either can make sense if…
the exposure is combined with a deliberate view on where returns should come from — geography or weighting — rather than adopted after a strong run.

Coverage, countries and sectors
Verified holdings, concentration, country and sector datasets are not currently connected. When available, each dataset will be labelled as official index data or Reference ETF holdings; listing domicile will not be presented as economic revenue exposure.
What this means in a portfolio
Adding S&P 500 Equal Weight to MSCI World does not reduce US exposure; it increases it while spreading it more evenly across US large caps. The combination is best read as a US size-tilt, not as diversification.
Common mistake
Treating equal weighting as a broad diversification decision. It changes how a single market is weighted; it does not add a single country, sector or company that the index did not already contain.
Historical comparison basis
Historical performance is represented using Grovcap-selected reference exchange-traded products. It is not the official index or spot return series. Fund or ETP returns can differ because of fees, taxes, tracking, cash positions, product structure and other implementation effects. Differences can reflect TER, tracking difference, withholding taxes, sampling, securities lending, cash drag, operating expenses, currency conversion and inception date.
No period is currently comparable across both reference products on a like-for-like currency, basis and reporting-date footing, so no return figures are shown. Grovcap never renders a missing return as 0.00%.
Grovcap does not currently hold a daily net-asset-value time series for these products. Indexed performance charts, annualised volatility, maximum drawdown and return-per-risk therefore remain unavailable rather than being estimated from period returns.
