Warren Buffett's favourite valuation indicator flashes buy signal

[NEW YORK] A key valuation metric touted by legendary investor Warren Buffett is signalling that equities are relatively cheap, bolstering the case that the sizzling rebound in US stocks has room to run.
The 'Buffett Indicator' measures the ratio of the total value of the US stock market via the Wilshire 5000 Index divided by the dollar value of US gross domestic product. It stands at its lowest level since early September – even after a bounce that has sent stocks screaming higher in recent weeks.
The 94-year-old chief executive of Berkshire Hathaway, which will hold its annual meeting in Omaha, Nebraska, this weekend, has said the 'single best measure of where valuations stand' was the ratio of the value of US publicly traded companies to the country's GDP. The indicator blared a warning late last year when it shot to a historic high, echoing similar signals sent during market peaks in 2021 and before the bursting of the dot-com bubble in 2000.
The measure is now at 180 per cent, around where it stood after an unwind of the Japanese yen carry trade sparked a brief but intense selloff last year. That stock-market rout cleared the path for a powerful S&P 500 Index rally in the closing months of 2024.
'This is a crucial indicator because it helps traders know when to deploy capital and buy stocks,' said Adam Sarhan, founder of 50 Park Investments, who has been piling into Big Tech stocks. 'There are reasons to still be concerned about the global trade war, but if Trump isn't playing hardball with tariffs, people are going to buy, buy, buy with valuations much more reasonably priced now.'
Valuation metrics of all types have taken on added significance this year, as investors try to determine if a tariff-fuelled sell-off has left stocks cheaper relative to their fundamentals. Those calculations are complicated by the S&P 500's 12 per cent bounce from its April lows, which has traders wondering whether to bet on momentum carrying the index further – or beef up hedges and place bearish bets on a trip back down. The index is still down nearly 9 per cent from its February record.

In addition to the unpredictable twists of US President Donald Trump's trade war, investors are bracing for several more weeks of earnings season and next week's Federal Reserve meeting as potential catalysts that could determine the trajectory of stocks.
For its part, the indicator is still above levels it plumbed during past market bottoms, including the Covid-19 sell-off of early 2020, when it fell to nearly 100 per cent. Other commonly used valuation gauges tell a similar story: The S&P 500, for example, now sits at 20.6 times forward earnings, down about 8 per cent from earlier this year, though still above the 10-year average of 18.6 times.
Critics of the Buffett indicator argue that, among other things, the measure may ignore the effects of elevated interest rates. Higher borrowing costs can eat into company profits and weigh on stock prices. Some strategists also maintain that valuation is a poor tool for timing market moves, since assets can stay cheap or expensive for a long time before correcting.
That said, few investors would ignore a measured lauded by Buffett, who is famous for buying on the cheap. Traders are eagerly awaiting Berkshire's annual meeting on Saturday (May 3), in part to glean any clues on whether Buffett has dipped into the company's cash pile – last reported at a record US$321 billion – to take advantage of bargains in the market.
It may be one of the last meetings for Buffett, who told shareholders in the company's annual letter earlier this year that 'it won't be long before' a successor takes over as CEO, likely Berkshire's Greg Abel.
Buffett 'has always been a long-term investor', said Scott Colyer, CEO at Advisors Asset Management. 'It will be crucial to hear what he says about the economy and whether cheaper valuations indeed pushed him to deploy all that cash to buy stocks during the sell-off.' BLOOMBERG
