Models such as Heston or Bachelier assume different dynamics than the simple log-normal dynamics in the Black-Scholes model and they give the correct option prices, whilst the underlying still has to compound at riskless drift due to no-arbitrage between the spot and the forward. | |
Aug 3 at 7:35 | comment | added | Frido | @Arshdeep 's answer is in essence correct. At risk of stating the obvious I'd like to add that the asset needs to be a tradable to use $r$ as drift. If it's not tradable you can't buy/sell it and hence you don't need to fund it and hence $r$ is not required. | |
