Relative Strength · CSE
Compare CSE returns with ASPI or S&P SL 20, then use correlation to see whether the same stocks have tended to rise and fall together. This is historical context, not a forecast.

Leave the selection empty for a benchmark-led view of current market leaders. Add stocks when you need a focused comparison.
Current scope
Benchmark-led market view

The service supplies a broad relative-strength ranking, and the leading six valid rows seed the correlation check.
2Set the comparison
Short windows emphasize recent moves; longer windows smooth some daily noise.
3Read the results
A positive relative-strength value means the stock returned more than the benchmark during the selected window. It does not mean the stock is cheap, safe or likely to keep outperforming.

Relative to ASPI
No valid result yet
Answer one · relative performance
Bars show stock return minus benchmark return over the selected window.
Answer two · co-movement
Pairs are easier to read on a phone than a matrix. Strong positive correlation means similar daily direction—not diversification, causation or guaranteed future behaviour.
Add at least two stocks, or wait for a valid market-led set, to inspect co-movement.
Method and limitations
Relative strength Stock return minus benchmark return over the chosen rolling or year-to-date period.
Correlation Pairwise daily-return correlation. It describes past co-movement and can change quickly.
Selection Market mode displays leading available rows; manual mode restricts the calculation to chosen symbols.
Not a ranking of quality Outperformance says nothing by itself about valuation, liquidity, risk or future returns.
