$ Now you say $V_t$ would be the risky asset. Quite perplexing. Edit the article to make this crystal crystal clear. We can easily contemplate what is a PnL once we determine what Now we have invested in. $endgroup$
Trader A has created some significant PnL, In the meantime Trader B will come out with almost nothing at all and his skipped out on volatility over the investing day which he could've profited off of experienced he been consistently hedging rather than just after each day.
Now, in the above mentioned rationalization, we assumed the stock was undertaking on some consistent vol whatsoever moments in time. Imagine if the intraday vol diverges considerably with the everyday vol? Ie: As an EXAGGERATION, say you examine some inventory and also you work out from your past ten working day closing rates the stock is accomplishing on the one vol. Just about closes wherever it opened day after day. You then opt to appear closer and measure vol in 30 moment increments rather then by day-to-day closing prices. If you look intraday/thirty min increments, the thing is the inventory moves a good deal, but dependant on closing rates performs continue to on a 1 vol.

The net influence of everything is the fact that improved delta hedging frequency does just contain the smoothing effect on P/L in excess of very long sufficient time horizons. But like you point out that you are subjected to one-off or unusual signify reversion (or trend) effects, but these dissipate more than massive samples.

So So how exactly does delta-hedging frequency just have an effect on the smoothness and variance of PnL if we can easily Obviously see it influences PnL alone in this example?
Which will depend on the rebalancing frequency. But "envisioned P&L" refers to a mean about all probable rate paths. So You can find not necessarily a contradiction here. $endgroup$
$begingroup$ The data I have found about delta hedging frequency and (gamma) PnL on this site and various Other individuals all reiterate the identical factor: which the frequency at which you delta-hedge only has an impact on the smoothness and variance of one's PnL.

Owing to your previous equality I realize that the "school circumstance" pnl can take into account the functionality on the money expense on the profit produced together the way, that is certainly $PnL_1rdelta t$.
So why create a PnL report. As I comprehend, The main reason for making a PnL report is to indicate the split of income/reduction amongst various parameters that impact bond cost. Is suitable? $endgroup$
