I have a portfolio management service as a trader where I charge $500 a fixed fee and then 25% of profits every month with $150 as fixed monthly fee.

Over the past 8 months, I have been managing 9 accounts for $150,000+ and have generated a cumulative return of 428% on the portfolio with 25% as my share of the profits. Not willing to expand my customer pool but do you suggest I increase the profit percentage to 35%?

The clients are happy but they won't be happy with 35% I believe.
