   Say this

   Give a number and build it, do not dodge it. Decompose into earnings growth and multiple: start from current index earnings, apply a growth rate you can defend, apply a multiple with a reason, and you have a level. Then give a range and say what the options market is currently implying, because that is the market's own answer.

   Then walk it

   1. The build: index level equals earnings times multiple. If earnings are growing 8 percent and the multiple is unchanged, you get 8 percent, and then you argue about the multiple — rates, risk premium and the growth outlook.
   2. Give one number and one range. 'My central case is up 6 to 8 percent from here, so roughly X, with a plausible band of minus 10 to plus 15.' Point forecasts are dishonest and no forecast is evasive; the number plus band is the professional answer.
   3. Then the market-implied cross-check, and this is where a derivatives candidate distinguishes themselves: the options market gives you a distribution for free. The at-the-money implied volatility annualised over the remaining period tells you the one standard deviation range the market is pricing, and the skew tells you the market's asymmetry.
   4. So you can say: the market is pricing about a plus or minus 12 percent one standard deviation range with a fat left tail, and my view is inside that range but with less downside than the skew implies — which is a trade, not just a forecast.
   5. Then the trade expression. If your view is modest upside with low volatility, sell a put spread or buy a call spread rather than buying outright calls. Matching the structure to the shape of the view is the point of being on a derivatives desk.
   6. And the risk to name: the level is driven by the multiple far more than by earnings over a one-year horizon, and the multiple is driven by rates and risk appetite, neither of which I can forecast. So the honest version is that my earnings number is a view and my multiple number is an assumption, and I would sensitise it.

   Where candidates lose it

   Refusing to give a number, or giving one with no construction. Both fail. Build it from earnings and multiple, then use the options market to give the range — that second step is free evidence and almost nobody does it.

   Expect next

   • What is the options market implying for the range?
   • Which part of your build are you least confident in?
   • How would you express that view in options rather than futures?
