SPY vs VOO vs IVV: which is the best?
If you’re thinking of investing in the S&P500 index for the long term, IVV is the most enticing option for investors at the point of writing. It has lower expense ratio and delivers the closest returns of the three ETFs, as compared to the S&P 500 index.
That said, the differences are quite insignificant. It is more important to start investing rather than spend too much time comparing between these three S&P 500 index funds.
A popular investing strategy is to invest in an index fund on a month basis, Alvin has shared the best brokers for regular investment plans if that’s what you’re planning to do.
However, if you’re thinking of buying or selling options on the S&P500 index, SPY is your best option (pun intended) due to its superior liquidity compared to VOO and IVV. This means that you’ll find a wider range of expiry dates and spreads.
Of course, if you wish to push the envelop and grow your money faster, you could do better by picking stocks that can outperform the S&P 500 index. Alvin shares how we pick such stocks to grow the Dr Wealth portfolio at his live webinar, join him at the next session.
