BAC has been s a bit lackluster, but using numerical analysis lets see what could have been done...
If the daily high had gone 5.6% or more above the previous day's high, that was an OK "go long" signal. 5.6% below the previous day's high was an OK "go short" signal. Buying should have been at the signal price, but selling should have been at the close following the signal.
Using this method for the past 12months would have given 213% compounded return with a drawdown of 18%.
There were 4 buy signals and 25 sell signals last year.
Another way to trade it would have been:
Go long if the price rises 1.4% above the open, go short at the next open. This would have given 315% in 55 long/short round trips. 13% drawdown.
Finally, this--
Go long if price was 4.1% above last closing price. Go short if price is at or below the last closing price.
Would have given 301% return, 11 long, 11 short round trips with 15% drawdown.
Only only one long/short switch per day, max for any of these systems.
Incidentally, just going short the whole year would have made 70% with 27% drawdown.
