Bull markets rarely begin when the world looks perfect. In fact, they usually begin when the news still looks terrible, investors are nervous, and the most common question in the room is: “What if things get worse?” That is exactly what the old market phrase means when it says bull markets climb a wall of worry.

We have all heard the phrase. It sounds like one of those market clichés that gets thrown around whenever investors are nervous. But like most clichés that survive for decades, it survives because there is truth in it. The phrase is believed to have emerged in the 1950s to describe a sustained rise in stock prices during periods of economic, political, or financial stress. The “wall” is made up of all the worries investors keep listing: war, inflation, oil shocks, elections, recessions, policy confusion, banking stress, or geopolitical conflict. Yet, even as these concerns dominate conversations, prices can keep moving higher.

This is not because markets are blind to risk. It is because markets are forward-looking. When fear is high, expectations are already low. Valuations often reflect bad news. Investors are cautious. Cash is waiting on the sidelines. And if the feared outcome does not fully materialise, or if policy makers respond with rate cuts, liquidity, reforms, or stimulus, the recovery can be surprisingly powerful.

History has shown this again and again.

During World War II, U.S. stocks fell around major shocks such as Pearl Harbor, but the Dow recovered that decline in less than a month. From 1939 to 1945, despite one of the most destructive conflicts in history, the Dow Jones Industrial Average rose roughly 50%, or a little over 7% annually. The lesson is not that war is good for markets. The lesson is that markets eventually price survival, adaptation, and recovery.

India has seen the same pattern. During the Gulf War period, the Sensex moved from around 1,200 in mid-1991 to nearly 4,000 by April 1992, helped by reforms and a dramatic change in India’s economic direction. After the 9/11 attacks, the index fell below 2,600, but recovered to around 5,800 by 2003. During the 2008 global financial crisis, the Sensex collapsed below 7,700, only to surge to a record 20,500 by end-2010. And during COVID, the Sensex fell below 26,000 in March 2020, when fear was at its peak, but crossed 61,000 by September 2021.

The pattern is clear. Deep fear often creates the base for the next rally.

This is why investors must be careful not to confuse frightening headlines with permanent damage. Crises feel overwhelming in real time. But markets do not wait for comfort. They begin recovering while the news is still ugly, while investors are still doubtful, and while the wall of worry is still standing.

The real danger often comes later, when the worries disappear, confidence becomes excessive, and investors believe nothing can go wrong. Until then, doubt itself can be fuel.

Bull markets do not climb smooth roads. They climb through fear, scepticism, and disbelief — one worry at a time.
