Connors' TPS

Strategy Rules

The operation of TPS can be summarized as follows:

• trade an S&P 500 ETF
• make sure the ETF trades above its 200-day moving average
• open a 10% long position, if the 2-period RSI is below 25 for two days in a row
• increase position size by 20%, if closing price dips below the previous entry price
• increase position size by 30%, if closing price dips below the previous entry price
• increase position size by 40%, if closing price dips below the previous entry price
• exit, when the 2-period RSI closes above 70
• use the same rules (with opposite direction) for the short side

For more detailed information on these rules and the rationale behind them, refer to Connors' book High Probability ETF Trading. The full C# source code is included in the TuringTrader.org open-source repository. Our implementation of TPS implements the rules as published in the book. However, we slightly altered the entry and exit points. Further, instead of trading on the market close, we modified the strategy to trade on the market open. This change frees investors from the requirement of being in front of a computer at the market close and seems more suitable for our readers.

We like the overall characteristics of this strategy a lot. Unfortunately, TPS is not trading often enough to use its capital efficiently. With these characteristics, we see TPS as an excellent supplement to other strategies. By combining a conservative portfolio with TPS, investors can increase their participation in stock market growth, while taking on only limited additional risk.

Diversification

While the S&P 500 index is diversified across many companies and industry sectors, it still represents only a single asset class. Even though TPS's equity curve appears very smooth, its tail-risk is identical to holding the S&P 500 index. This is augmented by the strategy aiming to by pull-backs.

Returns & Volatility

The equity curve shows how Connors’ strategy performs smoothly in almost all market regimes. While TPS typically trails the S&P 500, it does so with significantly less volatility and a slightly negative beta.

The Monte-Carlo simulation shows that TPS significantly changes the distribution of returns: The likelihood of positive returns improves, while the average returns are lower. Most importantly, the strategy’s downside is largely reduced.

Account & Tax Considerations

Connors’ strategy typically holds its positions for only a few days, resulting in a large number of wash sales and short-term capital gains. Because TPS takes long and short positions, it is not suitable for retirement accounts.

As TPS only invests in a single ETF, it can be used successfully with about $5,000 of capital.
