Key Takeaways
- Going public is about access: Companies go public primarily to gain legal, scalable access to public capital markets—not just to raise money once.
- IPOs solve visibility and accessibility: Public companies benefit from media coverage and easy stock trading, making capital raising much more efficient.
- P/E ratio reveals market expectations: A high P/E means investors are paying for future growth potential, while a low P/E might signal value or underlying problems.
- Price doesn’t always equal value: Stock prices are driven by market conditions, sector trends, and news—fundamentals often come last.
- Long-term focus wins: Ignore daily noise and invest in businesses you understand.
Introduction
Ever wonder why companies bother going public? Most people think it’s about raising money. But here’s what Wall Street doesn’t advertise: going public is really about getting a license to access other people’s money—legally, at scale, forever.
Understanding this fundamental truth changes how you think about the stock market and your investments.
What an IPO Actually Does
An IPO—Initial Public Offering—solves two big problems for companies:
- Visibility: It lets the whole world know about you through required disclosures and media coverage.
- Accessibility: It makes buying your stock easy—anyone with a brokerage account can own a piece.
This combination is like a superpower for raising capital. Before going public, a company has to pitch investors one by one. After? Capital flows in from anywhere in the world.
Why Being Public Changes Everything
Here’s what’s wild: going public transforms how a company is valued.
| Company Type | Annual Earnings | Typical Valuation |
|---|---|---|
| Private | $1 million | $1-2 million |
| Public | $1 million | $20-30 million |
The difference? The P/E ratio (Price-to-Earnings ratio)—the price investors pay per dollar of earnings.
The market pays for future potential, not just current profits. This is why some tech companies with minimal earnings can have valuations in the billions.
What Drives Stock Prices
Understanding what moves stock prices helps you invest smarter. Here’s the reality check—in rough order of impact:
- Market Conditions – Bull vs. bear market affects everything
- Sector Trends – Hot industries attract capital regardless of individual company quality
- News & Sentiment – Headlines move prices in the short term
- Company Fundamentals – The actual business performance (often last!)
Important: Don’t assume price always reflects real value. Short-term prices are driven by sentiment; long-term prices eventually reflect fundamentals.
How to Evaluate Stocks Like a Pro
When evaluating any stock, follow these steps:
- Check the P/E Ratio – Compare it to the industry average
- Understand what high P/E means – You’re paying premium prices for expected future growth
- Understand what low P/E signals – Could be value opportunity… or a warning sign
- Ignore daily noise – Most day-to-day price movements are meaningless
- Invest in what you understand – Focus on businesses you can hold long-term
Frequently Asked Questions
What is a P/E ratio and why does it matter?
The P/E (Price-to-Earnings) ratio shows how much investors pay for each dollar of company earnings. A P/E of 20 means you’re paying $20 for every $1 of annual profit. It helps you understand whether a stock is expensive or cheap relative to its earnings.
Why do some stocks with no profits have high valuations?
Investors buy these stocks based on expected future profits. Companies like early Amazon or Tesla had high valuations despite minimal profits because investors believed in their future growth potential. This is speculative and carries higher risk.
Should I buy stocks with low P/E ratios?
Not automatically. A low P/E can signal a bargain, but it might also indicate problems—declining industry, poor management, or hidden risks. Always investigate why the P/E is low before buying.
How often should I check my stock prices?
For long-term investors, checking weekly or monthly is plenty. Daily price movements are mostly noise and can trigger emotional decisions. Focus on company fundamentals and your investment thesis, not short-term fluctuations.
Bottom Line
Understanding how the stock market really works is your first step to financial freedom. Companies go public to access capital at scale. The market values future potential through the P/E ratio. And stock prices don’t always reflect true value.
Your strategy: Focus on businesses you understand, use P/E ratios to assess value, and ignore the daily noise. That’s how professional investors think—and now you can too.
