In your 40s, resist diversifying into areas you don't understand. Instead, invest 70% of your capital into your core area of expertise where you have an information advantage. Allocate 20% to adjacent opportunities and only 10% to "moonshot" ventures outside your competency.

Effective due diligence isn't a checklist, but the collection of many small data points—revenue, team retention, customer love, CVC interest. A strong investment is a "beam" where all points align positively. Any misalignment creates doubt and likely signals a "no," adhering to the "if it's not a hell yes, it's a no" rule.

True understanding of a business often comes only after owning it. Taking a small (e.g., 1%) starter position can initiate the research process and shift your perspective from a casual observer to a critical owner, revealing nuances and risks not apparent from the outside.

Top growth investors deliberately allocate more of their diligence effort to understanding and underwriting massive upside scenarios (10x+ returns) rather than concentrating on mitigating potential downside. The power-law nature of venture returns makes this a rational focus for generating exceptional performance.

The asymmetrical nature of stock returns, driven by power laws, means a handful of massive winners can more than compensate for numerous losers, even if half your investments fail. This is due to convex compounding, where upside is unlimited but downside is capped at 100%.

To avoid emotional spending that kills runway, analyze every major decision through three financial scenarios. A 'bear' case (e.g., revenue drops 10%), 'base' case (plan holds), and 'bull' case (revenue grows 10%). This sobering framework forces you to quantify risk and compare alternatives objectively before committing capital.

Cramer advises against 100% diversification into index funds. He suggests putting 50% of a portfolio in an S&P 500 fund as a safety net, while using the other 50% to invest in a small number of deeply researched stocks that you have a personal edge or conviction on.

Afeyan distinguishes risk (known probabilities) from uncertainty (unknown probabilities). Since breakthrough innovation deals with the unknown, traditional risk/reward models fail. The correct strategy is not to mitigate risk but to pursue multiple, diverse options to navigate uncertainty.

To balance execution with innovation, allocate 70% of resources to high-confidence initiatives, 20% to medium-confidence bets with significant upside, and 10% to low-confidence, "game-changing" experiments. This ensures delivery on core goals while pursuing high-growth opportunities.
