Frequently Asked Questions
What does this Shares calculator actually do?
It combines five fundamental ratios, Price-to-Book (P/B), Price-to-Earnings (P/E), Return on Equity (ROE), Dividend Yield, and a Margin of Safety derived from the Graham Number, into a single 0-100 score and a Buy / Hold / Sell verdict tuned for Nairobi Securities Exchange listings.
What is the Graham Number and why does PesaCalc use it?
The Graham Number = √(22.5 × EPS × Book Value per Share). It is Benjamin Graham's intrinsic-value formula for defensive investors, it caps P/E at 15 and P/B at 1.5, which is the historical "fair value" zone. We use it to set your Buy below price (Graham × 0.70, a 30% margin of safety) and Sell above price (Graham × 1.30, a 30% premium).
What P/E ratio is "good" on the NSE?
Long-term, the NSE 20 average P/E sits between 8 and 14. Anything below 10 is generally cheap, 10-15 is fair, 15-20 is rich, and above 25 is expensive (unless growth is exceptional, check the PEG ratio). Banks (KCB, Equity, COOP) usually trade at low single-digit P/Es; Safaricom and EABL trade higher.
When is the best time to buy a share?
Three signals stack together: (1) Price is below your "Buy below" target (Graham × 0.7), (2) P/B < 1.5 and P/E < 15, (3) ROE consistently > 15%. If all three line up and the company's sector is not in structural decline, that is the textbook Graham buy zone. Time the entry to dips during sector-wide selloffs, not company-specific bad news.
When should I sell my NSE shares?
Sell when one of these triggers fires: (1) Price exceeds your Sell above target (Graham × 1.3), (2) Fundamentals deteriorate, falling ROE, rising debt, profit warning, (3) You found a clearly better opportunity with higher score. Avoid panic selling on news alone, re-run the calculator with the new fundamentals first.
Where do I find P/B, P/E, EPS and book value for NSE stocks?
Free sources: NSE Daily Equity Report (nse.co.ke), the company's annual / half-year results PDF (Safaricom, Equity, KCB all publish these on their investor relations pages), Business Daily Africa Markets, Cytonn Weekly reports, and broker dashboards (Genghis, Faida, Dyer & Blair, AIB-AXYS). EPS = Net Profit ÷ Shares Outstanding. Book Value/share = Shareholder Equity ÷ Shares Outstanding.
How does the AI assistant work?
Click "AI Analysis Prompt" and the calculator builds a structured prompt containing every number you entered plus the computed signals. Copy it and paste into Claude.ai or any LLM, you will get a written investment thesis, risk flags, and sector context based on the company's fundamentals, no API setup required.
Is this financial advice?
No. PesaCalc is an educational tool. Share prices move on dozens of factors the calculator cannot see, politics, currency, management changes, accounting issues. Always cross-check with the company's latest filings, read the auditor's report, and consult a CMA-licensed investment adviser before committing capital. Past performance does not predict future returns.
