The UNTHINKABLE is About to Happen to Stocks (but most will invest wrong)

Tom Nash•Oct 11, 2026

Summary

Tom argues that the primary reason 90% of investors fail is the lack of a structured decision-making framework, which leads to emotional trading during market volatility. Tom states that investors should treat stocks as pieces of a billion-dollar business rather than just numbers on a screen, emphasizing that earnings and fundamentals are the only metrics that truly matter. Tom explains that "brain pasta" occurs when too much conflicting information enters the mind without a system to process it, causing people to sell winners too early and buy at market tops.

Tom introduces a specific "Double Down DCA" and "Trim Rule" system to manage volatility without needing to time the market. Tom suggests doubling down on investments when the S&P 500 is down 10% or individual stocks are down 20% from their yearly highs. Conversely, Tom advises trimming 10% of a position when it is up 50% and 20% when it is up 100% to generate cash flow and reduce risk. Tom also provides a 125-point quality test covering revenue growth, operating margins, cash-to-debt ratios, and leadership quality to identify exceptional companies.

Palantir (PLTR): Tom argues that Palantir is a generational wealth opportunity that many investors missed because they lacked conviction and a system. Tom states that focusing on fundamentals allowed for holding the stock from $6 to over $200. Tom emphasizes that the business improvements are more important than the share price movements.

Data Dog (DDOG): Tom highlights Data Dog as an example of why investors need a system to handle volatility and avoid selling too early. Tom states the stock was added to Tom's academy in January and has gained 120% since then. Tom explains that the key question for this stock is whether the business is getting better while the price stays flat.

Nvidia (NVDA): Tom uses Nvidia to demonstrate that the journey to 1500% gains is never linear and requires extreme patience. Tom states that high-quality companies like this require the skill to ignore emotional chaos created by the media. Tom argues that quality is always more important than trying to time the perfect entry price.

Tesla (TSLA): Tom mentions that Tesla makes up 20% of Tom's personal portfolio and has contributed to significant market outperformance. Tom states the stock is up 78% since September 2023. Tom uses this position as evidence that a structured system produces outlier results compared to the average benchmark.
