A 60-month non-principal-protected Nifty market-linked debenture (All Weather Equity, NPP) from Edelweiss. It pays nothing on Nifty gains up to 15%, then boosts the excess slab-wise, reaching a 40% return once the Nifty is up 30% and a 100% return once it is up 40%, above which the return is capped at 100%. The downside is one-for-one with the index.
