How professionals use this
Concentration is a feature, not a bug. The problem is when one event can break your plan.
Overlap matters. Different tickers can still be the same trade.
Correlation spikes in stress. Use the slider as a stress test assumption.
This is a screen. It does not replace full portfolio analysis.
Use it before adding size. Not after the drawdown starts.
Keep it simple. The goal is to spot obvious fragility.

What the score means
80 to 100: diversified enough for most regimes.
55 to 79: fine in calm tape, can bite during stress.
Below 55: concentration is driving risk. Reduce overlap or size.
