$begingroup$ I'm not sure That which you necessarily mean by "cross" results - the only real correlation is that they equally are capabilities of your modify in fundamental ($Delta S$)

The portfolio of bonds can have a particular DV01, which can be accustomed to compute the PnL. Can someone tell me if this is right or is there a thing more? For equities it ought to be just a straightforward sum of inventory costs at the end of day vs starting of working day? Is that this ideal?

And that i suggest "expected P&L" as the option premium (PnL) replicated by delta-hedging a position which can be calculated by subtracting recognized volatility from implied volatility.

So So how exactly does delta-hedging frequency just have an impact on the smoothness and variance of PnL if we could Obviously see it influences PnL alone in this example?

Which is dependent upon the rebalancing frequency. But "envisioned P&L" refers to a mean above all achievable price paths. So There may be not essentially a contradiction below. $endgroup$

In lots of situations (like bonds as part of your scenario) these prices are observed and unambiguous, That is 'marking to market place'; in other circumstances (where you might keep an illiquid more info exotic, just like a PRDC by way of example) this price tag is estimated through the Front Place of work pricer, This is often 'marking to design'.
