The claim is directly corroborated by the readable DayTraders article, which quotes The Kobeissi Letter and repeats the precise figures: ratio 0.41 and lowest since April 2025. X search results also surfaced the specific Kobeissi Letter post at https://x.com/KobeissiLetter/status/2042005062893879335 making the same statement. However, I could not fetch the X post itself, and I did not obtain a primary Bloomberg page or underlying index dataset in this run. Because the available evidence is consistent but mostly secondary/social rather than primary, the statement is best assessed as likely true rather than confirmed with high confidence.
