Jain believes his investment style was shaped more by surviving successive crises (Tequila, Asian, dot-com) than by bull markets. These "disasters" taught him crucial lessons about risk management that a smooth, decade-long bull market could never provide, creating a trial-by-fire education.

During a crisis, avoid the temptation to trade based on predictions of how events will unfold. Instead, use the market volatility to purchase pre-identified, resilient companies at better prices, accelerating your existing strategy rather than creating a reactive new one.

Investors often reject ideas in markets where previous companies failed, a bias they call "scar tissue." This creates an opportunity for founders who can identify a key change—like new AI technology or shifting consumer behavior—that makes a previously impossible idea now viable.

When rising interest rates became a headwind for its trading business, Robinhood didn't just cut costs and wait. Instead, it proactively launched products like Robinhood Gold and Retirement which were designed to thrive in a high-interest environment, actively adapting to the new market reality.

Contrary to the image of frantic buying, Baupost's 2008 deployment of $100M per day was the same painstaking, bottom-up analysis they conduct daily. The process doesn't change during a crisis; the environment simply presents a wider set of opportunities at lower prices. The key is maintaining analytical rigor amidst market chaos.

Companies that thrive in volatile economies combine two traits. They maintain superior operational fitness (profitability, agility) to withstand shocks, and they practice "spearfishing"—waiting patiently for the peak of a crisis to seize rare, transformative opportunities like buying a weakened competitor.

Rather than viewing shocks as black swan events that change everything, Eos's founder sees them as catalysts that rapidly accelerate underlying, long-term trends. For example, COVID supercharged the pre-existing decline in business travel and the rise of domestic leisure, validating long-held theses.

The 2008 crisis was Vanguard's defining moment. The widespread failure of 'smart' active managers to protect investors destroyed their credibility. In contrast, Vanguard's simple, non-profit model resonated with a distrustful public, causing its share of fund inflows to double almost overnight.

Betterment founder Jon Stein, who launched during the 2008 crisis, advises that uncertain economic times are ripe for new ventures. Fear reduces competition and can create unique market openings for founders willing to build while others are hesitant.
