$iShares Russell 2000 ETF(IWM)$ What some don't understand in terms of the difference between mega caps and large caps which are very liquid in terms of moving money into and out, small caps are much less liquid, or illiquid. So as money rotates out of Mag 7 and other large caps, it doesn't take much to move small caps up significantly. US Banks (large ones) have shown well with their earnings, and this is also parlaying into regional banks (small caps) as well as anticipation of going into a lower interest environment. Obviously there will be bumps in the road, and the past 4 trading days are extremely unusual. the question then is........"is the trend your friend" as well as the changes in the Fed rates and washed out valuations in small and also midcaps. they've been in pretty much a bear market the past 3 years. For those who bought IWM, Good luck and do your own DD too.
