In the event you hedge every moment, you wouldn't notice the total pnl of the larger sized SD moves however, you do capture the entire pnl in the smaller intraday moves. Conversely, if You merely hedge when a day, you won't notice the total pnl in the scaled-down intraday moves (like within your example) but you'll in return realize the complete pnl from your greater SD moves.
To create the two solutions similar it is best to visualize investing/borrowing $PnL_1$ at amount $r$ to ensure it stays while in the program until finally $t_2,.$ At that time your

You can even analyse the skewness and kurtosis of your time period PnL by getting 3rd and 4th moments of click here $Y_t$ respectively. Presumably you can conclude that for two sequence with equivalent expectation and variance, you will desire the one with constructive skew or lessen kurtosis, but perhaps not depending upon the confidence of the marketplace watch, etc..

The 2nd move is to move each and every variable that can impact your pnl to measure the contribution that a transform On this variable has on the overall pnl.
El reencuadre de PNL nos pone en el papel de un viudo evitando el dolor del duelo dando un salto hacia una relación con una mujer más joven, sin detenerse para decir un adiós apropiado a su esposa muerta".
