Long-Short Trend Following

Prior Work

We had discussed the SMA On/Off Switch and its ability to escape the worst days. Based on this finding, we setup a Tactical Theme that would go long NIFTYBEES and JUNIORBEES if the CNX 100 index is trading above its 50-day SMA and move into LIQUIDBEES otherwise.

What if, we could go long and short?

Naive Long-Short

Here’s how going long above 50-DMA and short below 50-DMA on the CNX 100 since 2001 compares:

CNX 100.02-Jan-2007.28-Apr-2015.long.short
Long-Short SMA (black), Long-Only SMA (red) and Buy & Hold (green)

It looks like going both long and short is not significantly better than a long-only tactical strategy.

Long-Short with Volatility

But what if, we add a volatility metric into the mix? The logic here is that corrections are preceded by a bout of volatility. So if you go short if either or the volatility signal or the 50-DMA indicates a negative bias and long otherwise:

CNX 100.02-Jan-2007.28-Apr-2015.long.short.volatility
Long-Short SMA w/ Volatility (black), Long-Only SMA w/ Volatility (red), Long-Only SMA (green) and Buy & Hold (blue)

It looks like there is significant alpha in the combination approach.

Long-Short NIFTY and BANKNIFTY

NIFTY returns since 2001:

And the same for the BANK NIFTY since 2006:

CNX BANK.12-Jan-2006.28-Apr-2015.long.short.volatility

NIFTY and BANKNIFTY since 2011:

CNX NIFTY.03-Jan-2011.28-Apr-2015.long.short.volatility

CNX BANK.03-Jan-2011.28-Apr-2015.long.short.volatility

NIFTY and BANKNIFTY since 2013:

CNX NIFTY.01-Jan-2013.28-Apr-2015.long.short.volatility

CNX BANK.01-Jan-2013.28-Apr-2015.long.short.volatility
Long-Short Combo (black), Long-Only Combo (red), Long-Only Tactical (green) and Buy & Hold (blue)

Conclusion

It appears that there is long-term alpha in using a combination of volatility and 50-DMA to implement a long-short strategy. To put this to test using real-time data, we have created a theme to make it easy for you to follow along: Trend Long-Short.
