Dotcom-Style Surges and Crashes, What Lessons Do Small Caps Teach?

The dotcom-era pattern of rapid rise followed by rapid collapse is a drama small caps often repeat.

The 1999~2000 dotcom bubble is a representative case where small-cap techs surged under market concentration in a short time.

Retail investor: "I missed that then, is there still a chance?"

Opportunity and risk always come together.

Liquidity drying up and earnings gaps typically follow a surge.

Why do small caps rise more?

Liquidity concentration and leverage from expectations are large factors.

Liquidity means prices move more when trading crowds into a stock.

What happened in the dotcom bubble?

Around 2000, related stocks overheated and valuations diverged widely.

Expectations were overvalued and not backed by earnings.

What about the KOSDAQ bio and game rallies since the 2010s?

Some bio and game names surged on clinical and new-release expectations.

After the rise, only a few were confirmed by earnings and long-term survival diverged.

Common recovery pattern after a surge?

Initial crash, short-term rebound, and prolonged trading range often appear.

Recovery speed depends on company fundamentals and how quickly market trust is restored.

PER → a metric showing how many years of earnings the price represents based on one year of profit.

What about delisting and dilution risks?

Among surging companies, some repeat rights offerings to raise funds.

Increase in shares → existing shareholders face dilution.

So, what to check first

→ 1. Check earnings and cash flow before following the price action.

→ 2. After a surge, watch volume and liquidity changes first.

→ 3. Size positions within a loss tolerance you can bear.
