I think you mean Bloat. Code doesn't take satisfaction from ruining
your day, it just feels like it does.

Your problem, as you have half realised, is the variables are not
initialised. The simple answer is to make sure they are initialised.
Put something like this as the FIRST line of your script:
$StockPrice = $ExercisePrice = 0;
Include all of the numeric variables into this line. You can replace the
'0' with an empty string if you prefer.
Your conditional check for the 'Reset' and 'Submit' will set those
variables that it needs to, and the remainder will still have default
values.
This will save you bloating the code with the 'IsSet' checking.
