Interesting question and very important one too and the answer is it is not a good strategy. Instead work on improving stop loss strategy. Let me explain in detail -
We traders are playing a probability based game. As it happens often, markets hits stop loss and then turn profitable, there is an equal probability (in fact slightly more) that markets may continue the journey much beyond stop loss creating huge losses.
Markets are known to create false beliefs and then trap traders. This scenario is just one of them. We place a trade, it hits stop loss, we are out and then market turns around. We feel we should not have kept stop loss and so we don’t do it in following trades and many times they turn out to be big losers wiping out all our profits. There are many who have taken deliveries in 2007-2008 and earlier and are still waiting having lost almost 100% of the capital. In fact this happens day in and day out with some or the other stock. Scan the markets on monthly charts and you will see many examples. In fact while Nifty/Sensex are making all time highs, there are only 10-20% stocks following them, rest of them are not. Run a Relative Performance scan on monthly charts for NSE/BSE all stocks and you will see what I mean. And it does not happen to only you and me, it can happen to any one. For e.g Rakesh Jhunjhunwala had bought A2Z maintenance which he recently sold for just 1/10 to 1/20 of the purchase price. But he can afford it, we cannot. He is a much smarter investor and has many more multi baggers. I have mentioned this e.g. just to illustrate that any one can have such huge losses.
Instead of removing the stop losses, one should work on stop loss strategy. Here are some guide lines
-Best way to determine correct stop losses is to back test and do walk forward testing.
-When trading with trend one can keep wider stop losses to avoid getting stopped out and missing the big move.
-In counter trend trades one should have tight stop losses since when the original trend resumes, it can move very sharply.
-Similarly stop losses should be tight while trading within narrow ranges. Any breakout could be a violent move and if happens against the trade will result in huge losses.
-In volatile markets, one should have wider stop losses to let the trade work out.
-Some possible stop losses - below/above recent swing lows/highs, high/low/close - atr multiple, n-period high/low/close (e.g. lowest low in last 2 days for long position), Parabolic Sar, Super Trend, Moving Averages, Trend lines and channel. List is endless. All of the above can be used individually or in combination. Also most of them can be used as trailing stop loss. One common technique is to use larger MA (50 or 20) initially and then shorten the MA period (to 20 or 10) as trade becomes favourable.
-One can combine position sizing with stop loss to keep same amount of risk on every trade. e.g. If SL is 10 one can may buy 100 while if the SL is 20 one may buy only 50 to keep risk of 1000 in both the scenarios.
All of the above are my personal suggestions but would advice to refer to authoritative sources
-Charles/Chuck LeBeau is one of the pioneers of computerised back testing and has worked extensively on Stop Loss and Exit strategies. He has several video courses which are very good.
-Dr. Van Tharp - very good material on risk management and position sizing.
Some final thoughts -
In simple terms stop loss is just a risk management process that helps in preventing unforeseen huge losses but it is the most important one. Remember the saying cut your losses and let your winners run - its stop loss that helps in cutting losses and trailing stop loss help in letting the profit runs.
Most important thing in trading is capital preservation. If one has capital one can always trade again but if one losses all the capital than how will one trade. Remember its not important that every trade be winner, but to be profitable over a period of time. Its like losing small battles to win the ultimate big war.
We win some, we lose some but in the end our win sum should be more than lose sum. While most of us concentrate on entries, it is the exit strategy that determines the out come.
