The S&P 500 is trading at a valuation that usually leads to weak returns for 10 years, but I don’t think investors should stop buying stocks. In fact, I think this would be a big mistake.

I don’t have any argument with the data and I’m half expecting a difficult year for the stock market in 2026. So why do I think investors should keep investing?
Cost averaging
A lot of investors follow a strategy known as cost averaging. This involves buying shares with a fixed amount on a regular basis, regardless of what’s going on with prices.
One of the best things with this approach is it removes any concerns about valuations. It doesn’t matter whether stocks are cheap or expensive, you just buy regularly and consistently.
It works as long as share prices go up over time. Investors end up with a cost basis in line with the historical average and they make money as long as stocks eventually go higher.
For anyone using this method, high share prices are no reason to stop buying. The plan is valuation-agnostic, so investors shouldn’t see this as important.
Value investing
Some investors, however, have strategies that do focus on valuations. And for anyone taking this type of approach, high price-to-earnings (P/E) ratios are something to pay attention to.
I’m in this position – I’m very uneasy at the idea of buying stocks at prices that I think are too high. But the solution for investors like me is straightforward – just don’t buy the S&P 500.
There are literally hundreds of individual stocks to consider at the moment. And the fact the US index as a whole is historically expensive doesn’t mean all of its constituents are.
In fact, the S&P 500 has become extremely concentrated around a few artificial intelligence (AI) names. But beyond these, there are a number of stocks that don’t look expensive at all.
Energy
One of the worst-performing sectors from the S&P 500 has been energy. But I think investors interested in valuations might look at the likes of ConocoPhillips (NYSE:COP) as a result.
Falling oil prices have been – and remain – a potential risk. But I think the company is in a strong position to withstand a downturn in commodity prices.
The firm’s assets typically have production costs between $30 and $35 a barrel. Its balance sheet is also strong, which should help with its resilience. And then there’s the dividend.
Despite falling prices, ConocoPhillips has returned almost $7bn to investors since the start of 2025. At its current market value, that’s a 6.5% return so far this year with more to come in Q4.
Opportunities
In general, high valuations aren’t a reason to stop buying stocks. For anyone looking to cost average, this is part of the plan and I think there are also opportunities for value investors.
It’s surprising to me that the US energy sector has struggled when one of the main challenges to AI growth in 2026 is how to power data centres. But I see attractive valuations there.
ConocoPhillips is one name that I think investors could consider. But for my own portfolio, there’s a slightly riskier oil stock outside the S&P 500 that I like even more at today’s prices.
