Legendary investor Warren Buffett once famously quipped:

Be fearful when others are greedy, and greedy when others are fearful.

In the face of this year's share market turbulence, that quote has never rung louder.

After years of rising markets and speculative fervour, in recent times Buffett has been quietly selling stocks and building a record cash pile at Berkshire Hathaway (NYSE: BRK.B).

Now, with US and global equities reeling from President Trump's aggressive trade tariff policies, the wisdom of Buffett's caution is looking eerily prophetic.

A market shake-up reminiscent of the past

According to Bell Potter, today's economic climate bears a striking resemblance to the early Trump administration—a period marked by similar policy shocks and global market jitters.

Trade tension headlines are back. Geopolitical noise is louder. The Nasdaq tumbled into bear market territory. And ASX shares haven't been spared either, with the ASX 200 down materially from its highs.

The market is clearly fearful. And that's precisely why Warren Buffett's warning may now signal a rare opportunity. Bell Potter recently said:

As we have mentioned before, these periods of elevated market volatility, while challenging for short-term market timing, frequently present compelling opportunities for disciplined, long-term investors.

Sentiment-driven sell-offs can impact all stocks, meaning even fundamentally sound businesses can experience valuation compression unrelated to their intrinsic worth. This creates valuable windows to acquire stakes in durable franchises at more reasonable valuations than prevailed previously.

Warren Buffett's playbook: cash first, courage second

Warren Buffett doesn't time markets perfectly—he doesn't pretend to.

But his strategy is clear: when fear dominates headlines, quality ASX shares often become available at attractive prices. This is when the Oracle of Omaha gets to work.

And we might be entering that zone.

Could this be your Buffett moment?

For long-term investors, periods of volatility often mark the beginning—not the end—of a wealth-building opportunity.

Many quality ASX shares, from stalwarts like biotech giant CSL Ltd (ASX: CSL) and investment bank Macquarie Group Ltd (ASX: MQG) to fast-growing disruptors like health imaging technology company Pro Medicus Ltd (ASX: PME) and online furniture and homewares retailer Temple & Webster Group Ltd (ASX: TPW), are trading at sharp discounts to what investors were willing to pay just a matter of weeks ago.

If you have ve been sitting on the sidelines, waiting for the perfect moment—this may be it. Not because anyone can pick a bottom, but because, as Buffett shows time and again, value appears when investors are being fearful.

So, is it time to be greedy? It just might be.
