TrimTabs International Free Cash Flow ETF (TTAI)
Outgained $SPX +16.26% since March 2020 swing lows. Fund only came into existence 4 months prior so no other practical comparison can be made. Although the founder Charles Biderman has been an expert on this subject since at least the mid 90's that I know of.
Curiously also the fund made a low March 12, '20 or 11 days prior to $SPX. Canary in a coalmine for the next drop?
edit: "Fund only came into existence 4 months prior" - actually looked at chart again and it has been open since mid 2017 and sideways mostly, till March '20 drop and then pop. Return since as I said above.
