YES!
If I'd liquidated on the close yesterday I would have missed the premarket EXPLOSION today. That's why I held it!!!!!!
Here is a very simple swing system that should demonstrate to anyone that there is value in holding overnight, and value in buying pullbacks in a trend.
The following system was run over the past 12 months, Oct 9, 2002 to Oct 9, 2003.
BUY RULE: Create a list of the DOW 30 stocks. Log the daily stochastic (RawK, 8 period) of each stock. When the overall AVERAGE RawK of all 30 stocks is below 30, buy all the next morning. (This is a good way of determining a market bottom, for any trading system that goes long.)
EXIT RULE #1: Do nothing for one day. The first day that the stock closes up, AND closes above your entry price, sell at the close of that day.
or
EXIT RULE #2: If stock has not sold after 5 days, wait until stock reaches entry price, then sell at the close of that day.
RESULTS: 337 trades. 79% profitable. 2.16 Win/Loss ratio.
225 net points gained. Average hold for winners: 4 days.
Note that this system did not specify the conditions on each stock at the time of purchase. It bought only on the average of the Dow 30 stocks. You can use your imagination, or your backtesting software, to comprehend the gains if you had looked at a larger universe of stocks for better opportunities when these same conditions existed.
You may also note, if you chart this system, that these conditions occured regularly each month. And each time this occured, it was an excellent buying opportunity.
And who said that technical studies are useless in a random market?
