Let's face it — the share market can be a stressful place when prices are falling, headlines are screaming, and your portfolio is flashing red.

But the truth is, volatility is part of the investment ride. And how you invest in ASX 200 shares when things get choppy can make all the difference between panic and peace of mind.

If I were building a portfolio today with low-stress, long-term performance in mind, here's exactly how I'd do it.

Stick to quality ASX 200 shares

When markets get jittery, you want to own ASX 200 shares that can keep growing, even when the economy wobbles. I'm talking about companies with wide moats, strong balance sheets, recurring revenue, and products or services people keep using no matter what.

That's why names like CSL Ltd (ASX: CSL), Goodman Group (ASX: GMG), and ResMed Inc. (ASX: RMD) continue to anchor many long-term portfolios — because they deliver over time, not just when everything is booming.

And with their shares down meaningfully from recent highs due to the broad market selloff, now could be a good time to take a closer look at them.

Add in high-conviction ASX ETFs

For even more peace of mind, I'd mix in a few top-shelf ASX exchange traded funds (ETFs) alongside those ASX 200 shares to do some of the heavy lifting for me.

Something like the Betashares Global Quality Leaders ETF (ASX: QLTY) for worldwide exposure to durable businesses, or the iShares S&P 500 ETF (ASX: IVV) for a no-fuss way to invest in the world's biggest and most profitable companies.

And for those willing to ride the occasional bump in the road, the Betashares Nasdaq 100 ETF (ASX: NDQ) brings long-term tech growth to the table — with a side of short-term drama now and then.

Don't forget income

Dividends can also be a powerful buffer when prices fall.

Reliable payers like Telstra Group Ltd (ASX: TLS) or Coles Group Ltd (ASX: COL) can provide steady income even during downturns, helping smooth out the emotional rollercoaster.

Foolish takeaway

The goal isn't to avoid volatility — it is to invest in a way that lets you ride it out without losing sleep. Focus on quality, diversify through smart ASX ETFs, and let dividends cushion the bumps.

Because at the end of the day, it is not about timing the market. It is about building a portfolio that can stand the test of time.
