Apologies to the OP if my question below is a "red herring" given his/her opening post, but since it seems some active ETF traders are contributing to this thread, I wanted to get opinions on the following ...
Have any of you yet noticed any effect on liquidity/spreads/volumes in respect of the leveraged members of "top 20/30 ETFs" since FINRA raised margin requirements for these on December 1st? I haven't, but I only follow closely a very small universe and so am keen to read the views of others ...
Thanks!
