(Bloomberg) — The steep recovery in equity markets over the past two weeks is typical of bear market rallies, and the erratic swings mean almost every investor will experience pain whichever direction the market suddenly moves.

Goldman Sachs Group Inc. (GS) strategist Peter Oppenheimer said “the asymmetry for equity investing is poor. Sharp rallies within bear markets are the norm, not the exception.”

The biggest market driver is still uncertainty, with no real long-term bullish or bearish conviction seen from investors. Price action is mainly fueled by short-term headlines and guesswork on how the quickly evolving US tariffs story will be told through corporate earnings and resetting valuations.

“If the tariff announcements are reversed quickly with little lasting economic damage, this does suggest that the downside risks are limited. Nonetheless, at current valuations, we also think the upside is limited,” Oppenheimer wrote in a note.

Investing becomes far more difficult in such a regime, when both upside and downside are seen as limited and decision making is caught in foggy headline risk. Market participants have to choose between chasing a fading rally then risk exiting too late, or missing out entirely on another squeeze higher. They want to avoid trap doors in a tricky macroeconomic environment while still being able to capture opportunities.

“This equities trade is nasty, and the one scenario that nobody wanted,” Nomura Securities cross-asset strategist Charlie McElligott said. Many investors were forced to de-risk when there was zero visibility on tariffs in early April, but are now being forced to buy into a rally very few had enough exposure to fully benefit from its performance.

There is confirmation of “holding your nose and forced to buy-back exposure” playing out in stock-index options, “despite most investors hating the eventual macro growth outlook ahead,” McElligott wrote in a note.

If history is any guide, one of the sharpest intra-month rebounds in stock market history in April may have exhausted gains. Since 1980, the global stock market underwent several bear market rallies, which on average lasted for 44 days and saw gains of 14%. And while this year’s global stocks decline isn’t officially a bear market, prices are up 18% from an intraday low hit on April 7.
