When individuals speak about inventory market development, the S&P 500 typically dominates the dialog. The US index has been fuelled by world-changing tendencies over the previous decade — synthetic intelligence, cloud-computing information centres, and the growth in semiconductor chips that energy each.
Unsurprisingly, it has been a golden period for American shares.
The index is up a formidable 221% prior to now 10 years, equating to annualised returns of 12.37% a 12 months. And that doesn’t even embrace reinvested dividends, which might considerably increase long-term returns. Whereas dividends within the US are typically decrease than within the UK — averaging round 2% — they nonetheless add precious compounding energy when reinvested.
Aiming for optimum S&P 500 publicity
The best approach to seize the total advantage of S&P 500’s development is thru a tracker fund – particularly one with accumulating dividends.
Two of the most well-liked choices are the Vanguard S&P 500 ETF (LSE: VUSA) and the iShares Core S&P 500 ETF, each of which have returned round 270% prior to now decade.

The Vanguard ETF specifically has change into a favorite of many buyers. It makes use of a passive indexing strategy, that means it’s market-weighted to attempt to replicate the S&P 500. Roughly 27% of the fund is concentrated within the high 5 firms, which embrace Nvidia, Apple, Microsoft, and Amazon.
Considered one of its greatest points of interest is price. The continuing cost is simply 0.07%, which is tiny in comparison with actively managed funds. Over the previous decade, it has delivered spectacular annualised returns of 15.16%.
After all, there are dangers. The ETF is concentrated in US firms, with tech giants dominating. This presents each sector and regional danger. For UK buyers, returns are additionally uncovered to foreign money swings between the pound and the greenback. And like every passive fund, it doesn’t provide any defensiveness in a market crash.
Calculating returns
So how a lot would a lump sum of £10k have grown prior to now decade? If invested within the Vanguard S&P 500 ETF in August 2015, it could now be price roughly £34,600. That’s the sort of compounding impact billionaire investor Warren Buffett typically talks about – regular development, boosted by reinvested dividends, doing its work over time.
Personally, I feel the Vanguard S&P 500 ETF is likely one of the greatest ‘set-and-forget’ funds to contemplate. It offers immediate publicity to the whole US market in a single easy decide. For newer or passive buyers, it saves the headache of analysing particular person shares whereas avoiding the chance of constructing dangerous selections.
That stated, an skilled investor with a knack for inventory choosing may nonetheless outperform it by constructing their very own portfolio.
How’s the FTSE 100 doing?
By comparability, the FTSE 100 has been sluggish. A £10,000 funding within the UK’s benchmark index would have grown simply 33% prior to now decade. Nonetheless, dividends make a world of distinction right here. Utilizing an accumulating FTSE 100 tracker fund, such because the Vanguard FTSE 100 UCITS ETF, the return rises to 61.8%.
That also lags the S&P 500 by a large margin, but it surely highlights the facility of reinvesting dividends, notably in a market just like the UK the place payouts are extra beneficiant.
For me, the distinction reinforces why the S&P 500 stays such a strong engine of wealth creation.
