VOO, QQQ, VTI, SCHD and VGT: What Actually Separates Them

Choosing among the most-owned index funds is one of the more confusing first portfolio decisions, not only for beginners but for anyone who has bought three of them thinking that counts as diversification. The work involves knowing what each fund actually holds, checking the overlap, comparing concentration and cost, and then picking one core rather than owning the same handful of companies at three concentrations.

On the other hand, a single broad fund as the core can do almost all of the job. VOO or VTI covers the US market cheaply. QQQ or VGT adds more growth if you can stomach the drops. SCHD leans toward income. Add to the core on a schedule, and you get the compounding without paying three expense ratios for the same names.

Here are some things you can do to tell these five funds apart, and to avoid buying Apple, Microsoft and Nvidia three times over.

The five funds, and what actually separates them

VOO, the S&P 500 at a 0.03% fee. The default answer when you are unsure, and there is no sophisticated reason to reject it. It gives you the 500 largest US companies, weighted by size, and every other fund on this list gets measured against it.

QQQ, the Nasdaq-100. Heavier in technology, lighter in banks and energy. It has beaten VOO over the last decade and fallen harder in bad ones, roughly 33% in 2022 against the S&P's 19%. Buying it means buying both halves of that trade, not just the upside.

VTI, essentially every listed US company. Tracks VOO closely because the giants dominate both, so the practical difference is small. What you get instead of a difference in returns is the whole haystack rather than the top of it, including the small caps VOO leaves out.

SCHD, screened for dividend quality. It lags growth-heavy funds in a bull market and holds up better in an ugly one, which is the trade it exists to make. It also pays several times the yield of the growth funds, a tax bill in a taxable account and compounding fuel in a retirement one.

VGT, pure technology. The strongest ten-year performer here and the most volatile. This is a conviction holding rather than a core one, and sizing it like a core holding is how people get hurt when the sector turns.

Four things to check before you buy

1. Check the overlap before buying more than one. VOO and VTI together add almost nothing that VTI alone does not already cover, and VGT layered on top of QQQ concentrates the same handful of mega-cap names twice. Look up the top ten holdings of each fund you already own before adding another, since the overlap is usually larger than it looks.

2. Weigh the fee against what it is actually worth. A 0.03% fee against a 0.20% one looks trivial over a year. Over thirty years on $100,000 growing at 7%, the gap works out to roughly $38,000 in the cheaper fund's favour, purely from less being skimmed annually. Still smaller than the effect of which fund you pick in the first place, so check the holdings before you optimise the fee.

3. Decide your technology concentration deliberately. VGT is nearly all tech, QQQ about half, VOO and VTI roughly a third, SCHD deliberately less. This is the single biggest driver of how these funds behave in both directions, and it should be a number you chose rather than one you backed into by owning three funds that all lean the same way.

4. Pick one core fund and resist owning all five. Owning all five is mostly owning the first one, VOO, with extra fees and extra decisions attached. Choose VOO or VTI as the core, add QQQ or VGT as a satellite only if you can stomach the drawdowns, and add SCHD only if you are closer to needing income than growing it.

What not to do

Do not rank by trailing ten-year return and buy whichever fund is on top. Every table above describes one specific decade, and it happened to be a decade where US mega-cap technology was the best-performing asset class in the world. That is not a forecast. There have been full decades where value or international beat growth handily, and ranking by trailing return systematically flatters whatever just worked, which is the most reliable way to buy in near a top.

Where this leaves you

Check what you already own for overlap, pick one core fund between VOO and VTI, and decide on purpose how much technology concentration the rest of your choices add. Add to it on a schedule rather than picking a new fund every time a different one has a good year, and dollar-cost averaging covers how to make that automatic.

If you already own three of these and want a second opinion on how much they actually overlap, that is a good question for the Discord below. The answer usually surprises people who thought they were diversified.

FAQ

Is it bad to own more than one of these funds? Not inherently, but check the overlap first. Owning VOO and VTI together adds almost nothing that VTI alone does not already cover.

Which one has the lowest fee? VOO, at 0.03%. All five are cheap by industry standards. The real differences are in what they hold, not what they cost.

Should I just pick the fund with the best ten-year return? No. That number describes the decade that already happened, not the one coming next.
