SD30TSR – Stock Doctor trailing stop loss 30% exit / 30% re-entry indicator (daily)


Following member feedback, Lincoln Indicators launched its technical indicator, SD30TSR in 2018. When applied to Star Stocks, SD30TSR combines both fundamental and technical analysis to assist in buy/sell decision making. Following further back-testing on Star Stock performance, the indicator was revised in 2020.

Stock Doctor's trailing stop loss 30% exit / 30% re-entry (daily) indicator provides investors with a simple to understand entry and exit signal, to help them manage downside risk to stocks.

This strategy is suitable for investors who are moderately sensitive to price declines, by setting a stop-loss limit at the 30% Trailing Stoploss line from the day a stock is listed. As soon as the price drops below the 30% Trailing Stoploss line, a 30% Trailing Re-entry line is established; which is a guide for the re-entry signal.   


How to apply as an exit strategy 

The stop loss level is set 30% below the stock price when a stock is listed. As the stock price reaches new closing highs, the 30% stop loss essentially ‘trails’ along ie. moves up to 30% below the closing high. Investors exit once the close price falls below this 30% trailing stop loss level.


How to apply as a re-entry strategy:
Investors re-enter once the stock rebounds 30% above its lowest closing price from when the stop loss was last triggered. As this strategy uses daily prices, investors need to monitor the triggers frequently.



  • Allows investors to minimise significant drawdowns (losses) within portfolios
  • Having a 30% buffer instead of a smaller percentage stop loss avoids significant churn to your portfolio.
  • The daily time frame provides a more active signal. It works well in fast-moving markets.
  • Simple to understand and implement.
  • Has historically improved portfolio returns during bear markets.


  • Usually, significant declines in the share price will lead to slippage ie. you will unlikely be able to sell the stock at a price which is exactly 30% below its closing highs.
  • The SD30TSR is a fixed percentage change in price and does not take into account the volatility of the underlying stock.
  • Following this indicator leads to higher churn and lower win rate than a non-rebalanced portfolio strategy.
  • There could be incidences where a stock may fall much more than 30% before the SD30TSR is triggered (i.e. when the stock falls close to 30%, rebounds but then falls again). As such investors need to be cognisant of their position sizing.

Utilising this indicator does not guarantee you will avoid all losses, reduce your losses or achieve improved investment performance.  The Indicator is an indication only of stock trends and is not a prediction of future outcomes.
