US large-cap equities
Overall verdict
MSCI USA provides broad us equities, while S&P 500 provides us large-cap equities. The decision is primarily about market breadth and construction, not which has recently performed better.
Quick Decision
Choose MSCI USA if…
you deliberately want broad us equities and it matches the intended portfolio role.
Choose S&P 500 if…
you deliberately want us large-cap equities and accept its distinct concentration and risks.
Either can make sense if…
the exposure, implementation and risks fit a clearly defined portfolio objective.

“Depends” means the category reflects an investor objective, not universal superiority.
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
Holding both does not automatically create two independent portfolios. Overlapping companies and regions can make the combination an intentional tilt toward the exposure emphasised by S&P 500.
Common mistake
Assuming that adding S&P 500 to MSCI USA automatically improves diversification, without checking overlap and concentration.
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.
Reference instruments used
One canonical European exchange-traded product per exposure, chosen by published rules: exact benchmark family, active and published, plain long-only, then accumulating, unhedged, longest usable history and largest established product.
