Pubmatic or Magnite which is the better buy

These two companies are in the CTV ad sector with competitors like Tradedesk I have both companies and I’m down 40% on magnite and down 11% on Pubmatic shall I continue to average down ? As I am in the advertising and marketing sector as my job so I’m very bullish on these companies even tho I’m confident on them I am worried about the economy and Fed issues I’m thinking is this the best time to deploy capital into the market since it has been very volatile
