< Hopefully you guys will be able to help me out. I will be watching your trades and learning from you.>-Jodi Segal-Lankry Jodi, based on the results of YOUR trading, asking us for help would be like that U.S. carrier group in the Gulf asking Liechenstein for help to take out Saddam Hussein. ROFLOL Nevertheless, let me offer my two cents. I presume that when you say "stop loss" that you are referring to a mental stop rather than an actual stop placed with your broker. It is well known that MMs will drop the bid in a Philly minute to scoop up stops. I put together a little Excel spreadsheet that attempts to address the following question about exit points: A stock runs up. Do you hold, waiting for further runup, or sell all or sell part? (Or a stock runs down, waiting for further weakness) The inputs to the sheet are: the number of shares, purchase price, runup price, projected 2nd runup, and fall back price, if the stock turns down. (Alternatively, you can also enter 1st drop, 2nd drop and rebound price for those issues that are falling). Spend some time picking these points or use a range of values. The spreadsheet computes profitability for various mixes of sell/hold % across perceived runup probabilitities. The PERFECT decision will be SELL or HOLD ALL.. However, individual risk/reward ratios and runup probabilities will produce a wide range of selections. The more you hold, the greater the potential for profits but the guaranteed minimum returns will decline as well. Different individuals will sacrifice some of their Min profit for potentially higher Max profits. As such, they will select different % sell/hold mixes that suit their own comfort levels. The spreadsheet also calculates something I call the Isoprofit Runup Probability (IRP). The IRP corresponds to the runup probability that yields identical expected profits for any mix of selling/holding. Thus, if your perceived(actual) runup probability is higher than the IRP, then you should hold all; otherwise sell all. Again, in practice, you will probably ignore the IRP and choose a sell/hold mix that satisfies your own requirements for safety(Min) while increasing your wishes for wealth(Max). NO MODEL OR PERSON CAN MAKE THIS DECISION FOR YOU. The model is but a guideline to use. If totally in doubt, trash the sheet and sell 50 % and hold 50 %. Historically, though, all stocks tend to pull back after a large runup. The sell all (after the 1st runup) decision should be the tie breaker when in doubt. You won't reap the rewards of the 2nd runup,should it occur, if you sell all. However, you'll most probably get the chance to buy back in after the pullback. On the other hand, if you hold all, and hold too long, you may not have the funds nor the desire to buy more shares after the pull back. If anyone has a web site, or if it can be done in SI, I'll E Mail the file for review. TG
