The S&P 500 jumped 23.3% final 12 months, the second consecutive annual rise above 20%. And itās already round 2% increased in 2025.
However is the surging index heading in direction of a correction (that’s, a ten% fall)? Listed here are my ideas.
Arguments for
Extremely, the S&P 500 has delivered a return above 20% in 4 out of the previous six years. On a complete return foundation (together with dividends), it has been above 25% for 4 of these years, with a Covid-struck 2020 producing āsimplyā 18.4%.
12 months | Value return | Whole return |
---|---|---|
2019 | 28.88% | 31.49% |
2020 | 16.26% | 18.40% |
2021 | 26.89% | 28.71% |
2022 | ā19.44% | ā18.11% |
2023 | 24.23% | 26.29% |
2024 | 23.31% | 25.02% |
Traditionally although, these returns are far increased than traditional for the index. Certainly, the final interval there have been such monster returns clumped collectively was within the late Nineteen Nineties. And we all know what adopted that growthā¦
12 months | Value return | Whole return |
---|---|---|
1995 | 34.11% | 37.58% |
1996 | 20.26% | 22.96% |
1997 | 31.01% | 33.36% |
1998 | 26.67% | 28.58% |
1999 | 19.53% | 21.04% |
2000 | ā10.14% | ā9.10% |
2001 | ā13.04% | ā11.89% |
2002 | ā23.37% | ā22.10% |
In fact, this doesnāt assure that one thing related will occur this time round. However each then and now, there was the daybreak of a revolutionary new expertise that was getting buyers excited (the web and synthetic intelligence (AI), respectively). May historical past be rhyming right here? Itās doable.
Furthermore, Donald Trump has promised/threatened widespread tariffs, which many economists predict might be inflationary. In that case, this is able to be a hindrance to rate of interest cuts.
Lastly, the index is extraordinarily richly valued, with a ahead price-to-earnings (P/E) ratio of 21.6. This excessive start line makes it harder for company earnings to develop at a charge that justifies the valuation.
The index carried out very strongly the final time Trump was accountable for the US financial system. Nonetheless, the a number of is at the moment round 27% increased than it was when he took workplace in early 2017. Subsequently, a correction may very well be on the playing cards.
Arguments towards
Yesterday (20 January), the brand new President was sworn in. In his speech, he promised to spice up client spending energy by reducing power payments, taxes, and inflation, thereby making the financial system stronger within the course of. He even talked about placing the American flag on Mars.
Given this optimism, it may very well be argued 2025 might be one more optimistic 12 months for the S&P 5OO. Speak about a US recession has light, animal spirits are sturdy, and rates of interest nonetheless look set to maneuver decrease.
How Iām responding
The temper within the US proper now’s extremely bullish. My hunch then is that the index will chug increased this 12 months, however that it receivedāt ship a 3rd straight double-digit return. Naturally, I may very well be completely fallacious.
What Iām extra sure about although is that particular S&P 500 shares seem grossly overvalued. One is Palantir Applied sciencesĀ (NASDAQ: PLTR), whose share worth has exploded 1,017% for the reason that begin of 2023.
Palantir offers AI options to each authorities organisations and corporations. It has been rising like wildfire, with third-quarter income up 30% 12 months on 12 months to $725m.
Income has truly accelerated for six straight quarters!

Palantir additionally generated a file $144m in web revenue. And CEO Alex Karp struck an extremely bullish tone: āA juggernaut is rising. That is the software program century, and we intend to take the complete market.ā
Clearly then, thereās quite a bit to love about this AI firm. Nonetheless, the inventory is buying and selling at an eye-watering price-to-sales (P/S) a number of of 66. The ahead P/E ratio is above 150. If progress normalises, these valuations are probably unsustainable.
Palantir is the kind of overvalued S&P 500 inventory that Iām avoiding proper now.
