Is it a good investing strategy to always to execute a "stop loss" on a stock at the purchase price so that you can go and quickly repurchase at the lower price the stock is moving too? Logically to me this makes sense, but not sure if this is considered overly risky or bad practice. I understand the even with a stop loss I may not get my exact request, but still sounds like it may worth doing.
You will lose out on your spread, you always pay a spread. Also, if you are looking at a strategy for using stop losses, try taking into account the support lines if you are going long. So, if the stock is on an upward trend but is dropping back from profit taking, your best best is to take a position closest to the next support line. You place your stop just below the support. this will give you the best chance of a winning position as most technical analysts will have looking towards the support as a buy back area. Obviously, in a bear market the opposite is true. If you have taken your position and the market move past the first resistance line, then bring your stop to just below that line as once resistance is broken, it then becomes support. You then have a profitable position with profit locked in. Leave the position to break the next resistance and repeat.
