$ In the "operate case" you liquidate the portfolio at $t_1$ realising its PnL (allow me to simplify the notation a little)

Vega and Theta are sensetivities to volatility and time, respectively, so their contribution could well be:

ExIRExIR 16711 bronze badge $endgroup$ one $begingroup$ Thanks for supporting, but does that imply theta pnl only partly offsets Gamma pnl instead of completely although implied vol = realized vol? Mainly because assuming interest charges are zero, there is no other source of building money. $endgroup$

So, can it be accurate to state then delta-hedging rebalancing frequency specifically influences the quantity of P&L then? $endgroup$

$begingroup$ Why does Gamma Pnl have exposure to realised volatility, but Vega Pnl only has exposure to implied volatility? I'm puzzled concerning why gamma pnl is afflicted (much more) by IV and why vega pnl isnt influenced (more) by RV?

Be aware: I realize for those who hedge discretely rather than consistently there'll be considered a hedging error, but remember to overlook this mistake for the objective of this query.

The purchase won't matter for unbiased brute-force P&L or for threat-theoretical P&L (Taylor sereis approximation in the P&L working with deltas - 1st order and gammas and cross-gammas - second buy chance measures). I believe you're inquiring about RTPL? $endgroup$

$begingroup$ Underneath the assumptions of GBM - specifically that periodic returns are impartial of each other - then hedging frequency should have 0 influence on the envisioned P/L with time.

Alternatively, the gamma PnL is paid to you personally about the side, not on the choice top quality, but in the investing pursuits inside the underlying you execute your hedging account.
