All tested models lost the vast majority of their alpha when tested out of sample. For example, DeepSeek 3.2's strategy generated +20.7% annualized alpha in-sample, and -1.0% out-of-sample. Bigger models had bigger drops in out-of-sample performance. More parameters just meant more memorization. Full writeup: vbase.com/blog/llm-alpha…

A new benchmark tested commercial LLMs' ability to pick stocks in two matched time periods: one inside their training window, one after. Meaning, your LLM's alpha might be mere memorization.

A backtest is only as clean as its dirtiest input, and in LLM-based strategies, the model itself may be the dirtiest input of all.

Serious investors ask every data provider the same question: “Is your data point-in-time?” When the answer is a credible yes, they lean in, and often pay a large premium. But why is point-in-time data so important? And why do so many providers who claim to have it, still face deal-killing skepticism and long trials? In our latest post, we break down why “point-in-time” has become the standard for top-tier data — and why so many still fail this basic test. vbase.com/blog/why-quant…

@AlfaMalli Which service are you using?

@InvestorMexican If you want to share a verifiable track record across multiple accounts, that's our cup of tea!

Many traders believe that if they can get good results, investors will beat a path to their door. This can be true but with some caveats. Investors have to trust the results, which can be a major challenge.

Creating a verifiable trading track record is shockingly difficult. To do it, you have to convince the person on the receiving end that a) What you're showing is complete and tamperproof. If they suspect you can go back in time to change any element of your record or that you can present an incomplete record (e.g. missing trades, accounts, start times, etc), your track record loses all credibility. b) You haven't cherry-picked the best of your many outcomes. How do you show that you haven't run other strategies the recipient isn't seeing? Plus, you have to do this while making the data easy to parse and analyze. Few people will spend hours parsing statements, trade data, etc.

Many aspiring traders and money managers believe they can use their brokerage statements to validate their track record to potential investors. Unfortunately, this approach lacks credibility and is unpersuasive to most employers and capital allocators. Why invest blood, sweat, and tears in building a strategy for beating the market only to have no one believe you did it? validityBase has built a better approach that is lightweight, low-cost and globally verifiable. vbase.com/blog/stop-usin…
