    Excited to be a contributor to Bloomberg Money, a brand new personal finance vertical. I’ll be doing a weekly-ish Q&A on the wild world of ETFs drawing on our team’s research. First one is out and on (what else?) SpaceX that I did w @joelwebershow. Link in

    Interesting, while LeverageShares has by far won the volume race, ProShares' $SPCF has taken in most cash $184, next most is only $45m (all of them took in at least something) for total of $308m. Won't really have clear pic for a week or two re who The One is.

    Another 41 ETFs filed by Corgi. Fun fact: there were 100 ETFs launched in June so far, Corgi was 50(!) of them. Never seen the zone flooded like this.

Who this account is

@jseyff is a widely followed public account. Traders typically monitor this account for headline-driven sentiment changes that can create short-term trading opportunities. In the last 30 days, its content clustered around general updates.

This section is written for traders: who this account represents and why its posts can matter for markets.

Alert strategy ideas

  • Treat this as a high-signal account: lower posting frequency can make each post more informationally dense for swing and macro positioning.
  • Build theme-based alerts around "etfs", "filed", "just" and map those to the sectors or instruments most exposed to that narrative.
  • Use the peak posting windows (12:00-13:00 UTC and 00:00-01:00 UTC) to tighten monitoring during likely headline clusters.
  • Pair instant post alerts with your execution checklist so you can react during the first market repricing rather than after social commentary spreads.
