● Historical calculator
Backtest a single ticker across every past call.
Pick a ticker, an amount, and a hold horizon. The calculator runs the math against every historical call we've published for that ticker — bought at the close on the call date, sold N trading days later. SPY comparison is over the same window so you can see whether the ticker actually outperformed the market. The site is new, so most tickers have fewer than 20 calls at any horizon; numbers below n=10 are illustrative, not statistically meaningful.
Pick a ticker to run the math.

Read this. These numbers are computed from historical close-to-close prices and treat each Bitinforming call as if you had bought at that day's close and sold at the close N trading days later. They include winning AND losing calls — nothing has been cherry-picked. This is not financial advice. Past performance does not predict future results. The signal that performed well over a small sample can stop working tomorrow. Use this to build intuition about distributions, not as a buy recommendation.
If the calculator changed how you see the signal, consider it.
Every digest costs roughly $3 in API spend (Claude for summarization, audio narration, historical price lookups). The site is free and ad-free. If the numbers above were useful, the tip jar keeps the pipeline running.
