$begingroup$ If you check out just an individual instance, it may appear to be the frequency of hedging immediately results the EV/Avg(Pnl), like in the problem you explained exactly where hedging each individual minute proved to become more rewarding.

$begingroup$ Undecided it is a legitimate issue! Gamma p/l is by definition the p/l because of understood volatility getting distinctive from implied.
The net influence of all that is that elevated delta hedging frequency does just have the smoothing effect on P/L about very long enough time horizons. But such as you indicate that you are exposed to just one-off or scarce suggest reversion (or development) effects, but these dissipate above massive samples.
So the considered listed here is the fact that a trader who delta-hedges each individual moment, along with a trader who hedges every close of day at sector near, will each contain the similar predicted earnings at alternative expiry and only their PnL smoothness/variance will vary. Let us put this to your check.
How Is that this legitimate nevertheless? Delta-hedging frequency incorporates a direct effect on your PnL, and not just the smoothness of it.
Now that's a very important amount (that gets described, and so on.) but that does not give you a lot of information on what created that pnl. The second action is to maneuver every variable that can have an effect on your pnl to measure the read more contribution that a improve On this variable has on the full pnl.
The second term is because of your modify in desire charge. $varepsilon$ is solely what You can not make clear. If every thing is neat, your $varepsilon$ shouldn't be as well significant. You can even see this is quite near a Taylor expansion when all the things is linear, And that's why you can use your length being an approximation for your 2nd time period.
However, the existence of significant autocorrelation in the return process would trace that we can easily trade employing futures/linear merchandise on the intraday horizon which would probably (just after accounting for liquidity and theta) establish far more rewarding to trade as opposed to delta hedging technique.
$begingroup$ I estimate every day pnl over a CDS situation utilizing the unfold adjust periods the CS01. On the other hand I wish to estimate the PnL for an extended trade which includes absent from a 5Y CDS to some 4Y with connected coupon payments. Lets contemplate:
