The answer in plain English

Expense ratio describes recurring scheme costs; tracking difference describes a return gap; tracking error concerns the variability of periodic gaps. The market spread is a separate trading cost. AUM can provide implementation context but cannot guarantee that a large trade will execute near a displayed reference value.

What to check

  • Record the official product identity and benchmark before comparing figures.
  • Use the same return period and sign convention for tracking difference.
  • Read current dated expenses rather than an old “lowest fee” article.
  • Inspect executable quotes and quantities, not simply the last traded price or daily volume.

A useful comparison

Expense ratioWhat recurring cost is disclosed?Does not include every trading cost
Tracking differenceHow large was the realised return gap?Historical and period-dependent
Tracking errorHow variable were periodic gaps?A low value can coexist with a steady shortfall
Bid–offer spreadWhat gap separates quoted buyers and sellers?Can change with time and trade size
AUMHow large is the scheme at that date?Not a guarantee of liquidity or performance

Make the distinction clear

Example: a hypothetical 0.05-percentage-point fee saving is not automatically worth a much worse one-time execution price for a small holding period. Compare costs in rupees over the intended amount and period, without assuming future spreads or tracking. Do not compare gold-mining equity with a physical-gold ETF as if the exposures were identical.

One final question before acting

Does the figure or document match the exact scheme, plan, option, period and purpose in your question? Keep the source date with the answer. For a real transaction or personal decision, the current scheme documents and your own records take priority over a saved educational example.
