## Instruction

```
All input files are under `/app`. Save your output file(s) under `/app/output`.

For this task, estimate the 95% Value at Risk (VaR) for a stock portfolio over two periods (2005-2006 and 2007-2009): compute daily returns, form equal-weighted portfolio returns, calculate losses, and take the 95th percentile of losses for each period; save the outputs to "result.csv" in the required format with exactly two columns named "VaR_95, 2005-2006" and "VaR_95, 2007-2009".
