Timing my next S&P 500 Lump Sum (10k-12k) considering Midterms and Geopolitical Volatility?

I’ve been a long-term S&P 500 investor for about 5 years now. Due to high international wire transfer fees ($50 per transfer), DCA is not a viable option for me. Instead, I usually do a Lump Sum of 10k–$12k USD about 2 or 3 times a year I had some bad luck with my timing earlier this year: I invested in mid-January, the day before Trump started the Greenland crisis, and the index has been falling ever since. I understand long term investors shouldn't be that concerned and I have no plans to withdraw funds for at least a decade, but I’d like to optimize my next investment as much as possible 1. **Midterm Elections:** historically, months leading up to midterm elections tend to be volatile, followed by a year of good performance. Would it be wiser to wait until late October/early November to invest? 2. **Iran War:** is right now a better time to invest, considering current prices? What are your personal strategies for investment this year? thanks
