https://github.com/pandas-dev/pandas-stubs/blob/main/pandas-stubs/core/indexes/period.pyi#L20

Missing these attributes, per https://pandas.pydata.org/docs/reference/api/pandas.PeriodIndex.html:

attribute	description
day	The days of the period.
dayofweek	The day of the week with Monday=0, Sunday=6.
day_of_week	The day of the week with Monday=0, Sunday=6.
dayofyear	The ordinal day of the year.
day_of_year	The ordinal day of the year.
days_in_month	The number of days in the month.
daysinmonth	The number of days in the month.
end_time	Get the Timestamp for the end of the period.
freq	Return the frequency object if it is set, otherwise None.
freqstr	Return the frequency object as a string if its set, otherwise None.
hour	The hour of the period.
is_leap_year	Logical indicating if the date belongs to a leap year.
minute	The minute of the period.
month	The month as January=1, December=12.
quarter	The quarter of the date.
second	The second of the period.
start_time	Get the Timestamp for the start of the period.
week	The week ordinal of the year.
weekday	The day of the week with Monday=0, Sunday=6.
weekofyear	The week ordinal of the year.
year	The year of the period.

And these methods:

method	description
asfreq([freq, how])	Convert the PeriodArray to the specified frequency freq.
strftime(*args, **kwargs)	Convert to Index using specified date_format.
to_timestamp([freq, how])	Cast to DatetimeArray/Index.

Example error:

error: "PeriodIndex" has no attribute "start_time"

Thanks for reporting this. Because of how pandas implements these accessors, it wasn't picked up when stubgen was used a long time ago.
