If you had a time machine and KNEW what stocks would do, would you trade every day?

Since trading affects the price, you would have a problem. Either the predictions are approximate for the short-term until you mess them up by trading. Alternatively, if the time machine knows the price based on its knowledge of whether you will trade or not, then it's already determined whether you would trade, and you can't change it.

Oh, and the SEC will take notice of your activities.

You wouldn't have to trade every day. You wouldn't need to worry about diversifying your portfolio or anything like that. I'd keep things simple by making fewer/bigger trades. Invest in one stock that's about to take off, then take that money and put it on another one that's about to take off. It would keep the bookkeeping simpler.

I already trade every day. Knowing what stocks to buy/sell would be the most fun you could have with your clothes on !

I would find one company that is going to grow a bunch and invest almost everything in it.

no, it is too much work

And would you then not diversify your portfolio no matter what the Bulls or bears said? If only you had this information exclusively

Sounds like a cristal ball!
