Duration (as in interest rate sensitivity) is very important for long term equity selection, especially at the moment with interest rates so low. High duration stocks (little pricing power, big current asset bases) – banks spring to mind - seem overpriced too me unless interest rates don’t move up for a long time. Duration margin seems negative in the equities market to me at the moment. However some of the lower duration stocks are much more attractive from a long term perspective. One of the few opportunities left in this time of financial suppression.
Basically the negative duration premium in equities makes the yield chase occurring now dangerous but still leaves opportunities for buying long term growth at a reasonable price.
Without voicing disagreement about the points made on interest rate sensitivity, the concept of duration as applied to equities when the phrase 'duration on XYZ stock' is used is calculated as per a bond. However, instead of coupons/capital, the FCF to equity owners or Dividends are used in making the determination. Hence, it is possible for an equity holding to be very long duration in circumstances where the company does not carry any debt at all.
I do not know of anyone who prices along an implied discount rate/duration curve in equities. I have only seen the calculation done once in the wild.
In this context, we can think of duration as the marginal change in the valuation of a stock for a small change in the discount rate implied from the FCF/DDM forecasts and current price. The longer the duration, the more sensitive it is to changes in the discount rate.
