SMI ETFs are Exchange-Traded Funds (ETFs) that aim to replicate the performance of the Swiss Market Index (SMI). Think of it as buying a single 'share' that gives you a tiny piece of Switzerland's 20 largest and most liquid blue-chip companies. Instead of painstakingly picking individual Swiss stocks like Nestlé or Roche, you get a pre-packaged basket of them all. These funds trade on stock exchanges just like regular stocks, making them an incredibly convenient way for European and American investors to gain exposure to the famously robust Swiss economy. The goal of an SMI ETF isn't to beat the market, but to be the market—or at least, the Swiss slice of it. It’s a classic tool for passive investing, offering instant diversification across Switzerland's corporate giants with a single click.
Before you buy an ETF that tracks it, you should know what’s under the hood. The Swiss Market Index, or SMI, is Switzerland's flagship stock index, managed by the SIX Swiss Exchange. It's the Swiss equivalent of the Dow Jones in the US or the DAX in Germany. The SMI is constructed from the 20 largest and most traded stocks on the Swiss exchange, weighted by their free-float market capitalization. This means the bigger the company, the more influence it has on the index's performance. And in Switzerland, “bigger” means gargantuan. Be aware: the SMI is famously top-heavy. The “Big Three”—Nestlé (food and beverage), Novartis (healthcare), and Roche (healthcare)—often make up more than 50% of the entire index. This concentration is a critical feature to understand. When you buy an SMI ETF, you're making a significant bet on the health of these three global giants.
Like a fine Swiss watch, investing in an SMI ETF has its intricate pros and cons.
Many followers of value investing, including Warren Buffett himself, have praised low-cost index funds as the best choice for most investors. So, does an SMI ETF fit the bill? Yes and no. A core tenet of value investing is to know what you own. An SMI ETF is not a vague bet on “the market”; it is a very specific, concentrated investment in 20 businesses, heavily weighted toward three. A value investor must ask: “Am I comfortable owning these specific companies at their current prices?” Buying an SMI ETF means you accept the market's current valuation for all 20 firms—the overvalued along with the undervalued. It's a compromise. It can be a perfectly sensible way to build a core position in high-quality, global businesses. However, it is not a substitute for the classic value approach of identifying individual, excellent companies trading at a discount to their intrinsic value. Think of it as “value-adjacent”: a solid, simple strategy, but one step removed from deep value analysis.
Not all SMI ETFs are created equal. When choosing one through your brokerage account, pay close attention to a few key details.
