Atlas Rank — Sector Rotation

Sector Rotation — catching sectors as they turn, before they lead.

Buy rule

Sectors are ranked by how much their strength rank has IMPROVED over the last 63 sessions, starting from a below-median base. A name enters when its sector is among the 3 fastest improvers and it is top-3 there by composite.

Sell rule

Holds until its sector stops improving (and hasn't graduated to an outright leader), or the name drops past the buffer. The buffer is deliberate hysteresis — winners are left to run instead of being churned out on small rank wiggles, which also lets gains reach the long-term tax rate.

Universe

Trades stocks drawn from the Atlas-scored Nifty 500, evaluated every session.

Which names

When more names qualify than there are open slots, the highest Atlas composite wins the slot.

Position sizing

Starts 100% in cash and buys the qualifying set at the next session's close (no look-ahead). Each position capped at 10% (~10 slots), execution costs in the NAV, FIFO tax ledger on every sale.
