Catalyst

An event or piece of information that triggers a significant price movement in a stock.

What Is a Catalyst?

A catalyst in investing is any event, announcement, or data point that triggers a significant change in a stock's price. Catalysts are what transform a static stock into a moving one — they provide the "reason" for the market to re-price a security. Without catalysts, stocks would drift sideways indefinitely.

Types of Catalysts

• Earnings reports: The most common and predictable catalysts. Every public company reports quarterly, creating 4 predictable events per year.
• Guidance changes: When a company raises or lowers its forward guidance, it changes the market's expectations for future quarters.
• Analyst actions: Upgrades, downgrades, and price target changes from influential analysts can move stocks significantly.
• FDA approvals: For biotech and pharma companies, a drug approval or rejection is the ultimate binary catalyst.
• M&A activity: Acquisition announcements typically cause the target stock to gap up toward the offer price.
• Macro events: Fed rate decisions, economic data releases, and geopolitical events affect entire sectors or markets.

Earnings as the Ultimate Catalyst

Earnings reports are unique catalysts because they're scheduled in advance. Unlike surprise news events, you know exactly when earnings will be reported. This is what makes EarningsShot powerful — you can prepare, analyze, and make your prediction before the catalyst hits, then see how the market reacts.
