I did some tweaking to the Highflier system after the last couple days: Buy funds which are above 55 on the 100-day RSI and above the 200-day SMA. Sell funds which are below 50 on the 100-day RSI and below the 200-day SMA. Get out when you can, not when you have to. Look on the other side of the fence for greener grass.

Largely the same as Mebane Faber and Jerry Robinson too. But they rebalance only yearly or quarterly.
The shared momentum list is not a strategy. However, elements of momentum (crossing negative or positive, significant shift, pair trades, value, contrarian etc) can be (and are) strategic tactical components.
You take your S&P ETF sectors and you rate them by relative strength and you put your money into the top-rated one, two or three ETFs and rebalance your portfolio as needed and you're supposed to beat SPY about 70% of the time. Beating the market isn't necessarily making money, though, because SPY could lose money.
