What you are encountering is the large % of market cap in QQQ that is represented by what is called the Mag 7. Only 100 stocks in QQQ so those 7 affect QQQ more through their market caps being a higher % of the ETF than with the SPY ETF, which is 500 stocks. So, actually your're pretty much trading those 7 stocks, more or less in QQQ and of course they have been on an upward trend, except for recently.
Focusing on one asset only can make you a master, but only on just that. What will you do when the market is not good for you to trade that?
I am all for just focusing and trading just one asset, I mean we all know a bunch of people who only work on gold and make awesome money from it, so why not do the same in sticks? I do realize the mechanisms of both assets are different but the similarities are there too.
True. As is always the case, the devil is in the details. Perhaps, OP does have a real edge compare to me. I just bet on the bull market.
I day trade futures. I started trading Russell 2000 ~ 2 decades ago. As time went by, I added more and more futures. Now I trade ~ 20 - 30 futures. More futures - more trading opportunities. Most importantly, you can use intermarket correlations. You rarely see day traders trading one futures in the trading houses.
look at rty vs es vs NQ. A few minutes ago, US index futures went down. rty was the most trendy. ES and NQ movement was rather choppy.
