Terms of use
By using this website, you accept these terms in full. If you do not agree with them, please do not use the site.
Maineblock's tools and guides are educational. They are not financial, investment, medical, or legal advice. Verify anything consequential with a qualified professional.
Stock Valuation Studio
Valuations run on the feed price shown with each workup. Prices are delayed, fundamentals are cached, and the sources are unofficial. Every value the Studio produces is an estimate from a valuation model working on a company's public filings and on the model's stated assumptions. Estimates are inherently uncertain: reasonable models working from the same filings can reach different values, and an estimate is a model's judgment at a moment in time, not a prediction of the price a stock will trade for. Values change as new filings and prices arrive.
The Studio's charts display price history so it can be studied alongside each workup. The prices behind the charts are delayed and come from the same unofficial sources as the workup prices. Charts can be exported as images only. Maineblock does not redistribute raw price data: the Studio's data exports carry computed statistics, such as returns and valuation figures, and never a price series.
The Studio is published for educational and informational purposes only. Nothing it produces is financial advice or investment advice, and nothing is a recommendation, offer, or solicitation to buy, sell, or hold any security or to follow any investment strategy. The Studio does not know your circumstances, goals, or tolerance for risk, and its output is not personalized to you; it is not a substitute for advice from a licensed financial professional who knows your situation. Using the Studio creates no professional, advisory, or fiduciary relationship between you and Maineblock LLC.
Any decision you make is yours alone. Maineblock LLC and its tools are not a party to your decisions, do not share in their outcomes, and accept no responsibility or liability for any loss or damage that arises from relying on the Studio's figures. The underlying data comes from third-party and public sources and feeds; it can be delayed, incomplete, revised, or wrong, and Maineblock LLC makes no guarantee of its accuracy or completeness. Verify any figure independently before you act on it. Where the Studio shows results from earlier periods, they are shown to explain the method; past results do not predict future returns.
The Studio includes an AI assistant, MIA, powered by Claude, an AI service by Anthropic. When you ask MIA a question, your question and the text of the valuation workup on your screen are sent to Anthropic so Claude can compose the answer from that workup. MIA's responses are generated by AI. They may be inaccurate or incomplete, and they are provided for information only, not as financial advice. Maineblock is not liable for content MIA produces or for decisions made in reliance on it. Verify any figure that matters in the Studio itself.
Analysis Studio
Analysis Studio runs in your browser on the data you load; nothing is uploaded. Its results follow from that data and the method you choose, so they describe the data you brought.
Promotion: through March 31, 2027, every Analysis Studio module is free to use on screen. Downloads and copying remain part of the subscription during the promotion.
SAE Studio
SAE Studio produces model-based estimates for small areas. They are estimates, not counts, and how much trust each one deserves depends on the survey data behind it; the Studio reports the uncertainty with every estimate.
SAE Studio estimates proportions only: the outcome is a share between 0 and 1. In the free trial, a run shows at most ten areas of your own data on screen; a license shows every area.
The Studio's default disclosure preset (the Standard preset) suppresses estimates that do not meet its presentation rules, including a minimum effective sample size. At about 20 respondents per area, nearly every estimate falls below that minimum: measured at flagship scale, the preset published 0.93 percent of area estimates with frame counts supplied and 0.00 percent without them, so at that sample size it suppresses nearly all exported estimates. The methods report generated with every run carries the full measured record.
Maine Mood
Maine Mood results report what the survey's respondents said, weighted to match the state's population. They are a snapshot of opinion from the weeks the survey ran.
Daily 7
The Daily 7 is an educational watchlist, published for informational purposes only. It is not a recommendation to buy or sell any security. The seven names are drawn from market attention and the day's news; a name appears because people are watching it, and inclusion on the list is not an endorsement of the company or its stock. Prices update while the market is open and can move quickly. Check a live quote before acting on a pick.
The options commentary describes how the day's names are being traded and the leans other traders are taking. It is description, not a trade recommendation. Options carry substantial risk, are not suitable for every investor, and can lose their full value quickly.
Nothing in the Daily 7 is financial advice or investment advice, and nothing is a recommendation, offer, or solicitation to buy, sell, or hold any security or to follow any strategy. The list is the same for every reader; it does not consider your circumstances, goals, or tolerance for risk, and it is not a substitute for advice from a licensed financial professional who knows your situation. Reading the Daily 7 creates no professional, advisory, or fiduciary relationship between you and Maineblock LLC.
Prices can gap up or down between editions, and a pick can fall sharply as easily as it can rise. Any decision you make is yours alone: Maineblock LLC and its tools are not a party to your decisions, do not share in their outcomes, and accept no responsibility or liability for any loss or damage that arises from relying on the list. The figures come from third-party and public sources and feeds; they can be delayed, incomplete, revised, or wrong, and no guarantee of their accuracy or completeness is made. Verify the figures independently before you act on them.
Statistics and Data Analysis for Investing and Trading
The book's examples use historical data to teach each method. They are illustrations to learn from, not live guidance for today's market.
Automated Stock Valuation Suite
The suite runs in Google Sheets and pulls live public data feeds. Those feeds can be delayed or revised, and the suite's figures refresh as the feeds update.
Free calculators and templates
Every calculator states its assumptions and approximations (for example, the t-test power tool uses a normal approximation, disclosed on the page). Results are only as good as your inputs: garbage in, ruin out. The templates are starting points; adapt them to your own numbers before you rely on them.
Free downloads
Free templates are yours for any use, including commercial work. Premium products are sold via Gumroad under Gumroad's terms.
Licensing
A paid license covers one person. The license key is sent by email at purchase.
The license stays valid for the paid year, even if auto-renewal is turned off. Every license email includes a control that turns off auto-renewal from the email itself. The purchase receipt carries that control. The pre-renewal email carries it as well.
When a payment is refunded, the license tied to that payment is revoked.
Stock Valuation Studio is free. It has no license and no paid tier.
Refunds
Paid Studio subscriptions (SAE Studio, $149 per year; Analysis Studio, $299 per year):
A full refund is available within 14 days of the initial purchase, only if no paid feature has been used.
The first paid action closes the refund window. Paid actions include an export, a workbook or script download, copying results, a saved board or model, and a paid procedure run.
Renewals carry a 7-day grace period. A renewal is refunded in full if no paid feature was used in the new cycle. A reminder email is sent 7 days before a renewal charges.
Paid downloads (the book and the spreadsheet suite):
A download is a final sale once it has been downloaded.
A download that was never downloaded is refundable within 14 days.
Duplicate billing is refundable within 14 days.
Verified technical defects:
If a paid feature fails as documented, and the failure is reported and stays unresolved for 5 business days, a full refund is available within 30 days of the report.
