Is the Vanguard S&P 500 ETF Index Fund a Buy Now?

Key Points

The Vanguard S&P 500 ETF (NYSEMKT: VOO) is arguably the best way to match the returns of the American stock market. It's one of the three largest exchange-traded funds (ETFs) based on the popular S&P 500 (SNPINDEX: ^GSPC) market index, which reflects the performance of 500 top-quality domestic companies. The fund's annual fees are minimal. The Vanguard group behind the scenes was built around the investor-friendly policies of founder John Bogle . If you want to follow the broader market, the Vanguard S&P 500 ETF is always a great place to start.

But there's a more general question in play here. Is this the time to get into the stock market, in the first place?

Let me show you why the answer is "yes," no matter what you think the stock market might do in 2025 or over the next couple of years. You may not want to go all-in with a large purchase today, but this moment is as good as any other to start a new Vanguard S&P 500 ETF position -- slowly.

Market predictions are all over the map

First and foremost, I can't tell you exactly what the stock will do over the summer of 2025. There are tons of conflicting opinions on this matter -- probably more than usual.

Hedge funds are reportedly buying lots of promising tech stocks right now, suggesting a bullish market outlook in this group. At the same time, bearish short-selling activity is on the rise and many market watchers expect a full-fledged recession amid the Trump administration's unpredictable tariffs.

So the stock market might be falling off a cliff, or preparing for a majestic surge. The real outcome probably lies between these extremes. Trying to time the market in this erratic economy sounds like a terrible idea.

Perfect timing is mostly just luck

In all fairness, the starting price for any investment can make a significant difference to your long-term results. If you invested $3,000 in an S&P 500 index fund at the start of 2008, you'd have a total return of $16,970 by June 2, 2025. But if you saw stocks trading at unreasonable valuations at back then, and held off on making that $3,000 investment until early 2009 instead, your account would show a total return of $26,940 instead. The S&P 500 dipped as much as 48% lower in the subprime mortgage crisis.
