Attention, investors - the stock market bubble is about to burst, according to leading economic forecasters. A new report from Capital Economics predicts that the long-running bull market will come crashing down in 2027, ushering in a new era of turmoil and upheaval.

What this really means is that the party is about to end for tech giants and high-flying growth stocks. The firm's chief markets economist, John Higgins, warns that the current "rotation" away from tech and toward value-focused sectors like energy is a "warning of trouble ahead."

Echoes of the Dotcom Bust

Higgins draws a stark parallel between the present-day market and the late stages of the infamous dotcom bubble in the early 2000s. Just as small-cap and value stocks quietly began outperforming their larger, growthier counterparts around 11 months before the 2000 crash, we're now seeing a similar dynamic play out.

According to MSCI indexes, small-cap, value, and defensive stocks have each outpaced their large-cap, growth, and cyclical peers by around 10 percentage points so far in 2026. "If the aftermath of the dotcom era is any guide," Higgins wrote, "the bursting of the *next* bubble in the stock market...might be followed by periods in which small-cap and value stocks outperformed their peers for a very long time."

A Reckoning for Tech

The bigger picture here is that the extraordinary bull run fueled by artificial intelligence and other transformative technologies is about to meet a reckoning. As Markets Insider reports, Capital Economics sees the S&P 500 surging as high as 8,000 in 2026 before crashing back down to 7,000 - a 13% drop that could even reach 30% in a worst-case scenario.

The firm believes that investors will eventually realize tech valuations have become unsustainable, leading to a painful comeuppance for the sector. And as Senator Elizabeth Warren warned, any government intervention to prop up the market would "disproportionately benefit crypto billionaires" - a group that has also seen meteoric gains in recent years.

The message is clear: the good times for high-flying tech and crypto stocks are numbered. Buckle up, because the market is headed for a reckoning.
