Talk Your Book: Invest by Avoiding the Losers

Avoiding Losers

Julian Koski from New Age Alpha emphasizes the importance of avoiding losers rather than picking winners in investment portfolios. He explains that traditional methods focus on predicting future winners, which is inherently uncertain. Instead, his approach uses historical data and current stock prices to calculate the probability of a stock failing to meet its growth expectations 1. This method aims to minimize risk by avoiding stocks with high failure probabilities.

Picking the winners requires you have knowledge of the future. And the future by definition is not known.

--- Julian Koski

Koski's strategy involves analyzing financial statements and stock prices to determine the implied growth rate and the likelihood of achieving it 2.

   

Probability-Based Investing

Probability-based investing is central to Koski's methodology. He argues that risk comes from human behavior and market sentiment rather than traditional metrics like beta or volatility 3. By calculating the implied revenues and comparing them to historical performance, his team can assess the probability of a stock meeting its growth targets.

We're looking at the forward-looking odds of that. We're saying, based on where that stock price is today, the scariest thing of the market today are people or humans and human behavior around the stock price.

--- Julian Koski

This dynamic approach allows for adjustments over time, ensuring that the investment strategy remains relevant and effective 4.

   

Market Mispricing

Koski also focuses on identifying market mispricings through quantitative analysis. He believes that large-cap stocks, often considered efficiently priced, actually offer the best opportunities for his strategy 5. By betting against analysts' forecasts, which he argues are often influenced by human biases, Koski aims to exploit these inefficiencies.

Because nobody is looking at risk this way. Nobody. And when you look at risk this way, that's when you see where the inefficiencies actually are.

--- Julian Koski

He provides examples like Boeing and Pfizer, where market sentiment may not align with the companies' actual performance, highlighting the importance of waiting for proof before investing 6.
