$MAX S&P 500 4X Leveraged ETN (SPYU.US)$ under profile says ...

under profile says this is spy except tech based off $Proshares S&P 500 Ex-Technology Etf (SPXT.US)$  aum. the largest holding is Amazon.  there's no msft appl nvidia. I think they do this for less volatility because it's 4x. either way it pretty much follows spy to a t. I've held it through many corrections and it'll jump back up quicker than anything else.  several times I've been down a lot then back up again the same amount the next day. very good tool to learn the way spy moves . in a downtrend id jump into it deep in red or buy a share wait for it to dump then buy more later that day would be top position. leap of faith into bloodbath. get in low enough you really don't want to sell then objective here is to outperform the market
