Show the working
- Risk budget = Rs 10,00,000.00 × 1.00% = Rs 10,000.00
- Risk per share = Rs 500.00 − Rs 460.00 = Rs 40.00
- Shares = Rs 10,000.00 ÷ Rs 40.00 = 250
How this is worked out
- Position size falls out of the distance to your stop, not out of how much you like the idea. A wider stop means fewer shares for the same rupee risk.
- Losses and gains are not symmetric: a 50% loss needs a 100% gain to recover. Capping the size of a single loss matters more than picking well.
- A stop placed inside the stock's ordinary daily range will be hit by noise rather than by being wrong. Size the stop from the stock's own volatility first, then read the position size off it.
On NEPSE
NEPSE has no intraday trading and daily circuit limits, so a stop cannot always be executed at your price. Treat the stop as a decision level, not a guarantee.
