How to avoid Major Drawdowns?

Written by 2 min read

There are many methods to identify if markets are overheated (Sellers Market) or under heated (Buyers Market), We can use

  • Historical PE vs Current PE

  • Historical book Value vs Current Book Value

  • Number of Stock making highs

  • Breadth of market (Number of up vs downs)

  • Overall Volume across markets and many more

In this post I want to delve on a simple Moving Average Cross Over Indicator.

The crux is below

You monitor 10 week and 20 week EMA, if the 10 week EMA > 20 Week EMA then you are long otherwise you are out of market or short

I used this indicator for NSE 500 (India) , S&P 500 (USA) and ASX 200 (Australia) the results were pretty consistent as you can see below, the indicator moved you in cash on multiple key crash points in past

Weekly SPY chart from 1999 to 2024 with a 10 vs 20 EMA background: green when in the market, red when out, including the 2001, 2008 and 2022 falls
Weekly NSE 500 chart from 2000 to 2024 with a 10 vs 20 EMA background showing in-market green and out-of-market red periods
Weekly ASX 200 (XJO) chart from 1998 to 2024 with a 10 vs 20 EMA background showing in-market and out-of-market periods

The Green background in chart indicates, that you were long or ‘in’ market , the red background indicates you are short or out of market

I also looked deeper how this would have fared in large crashes, I evaluated

  • Dot com bust

  • Global Financial Crisis

  • Covid Crisis

  • Russia Ukraine War

Lets look at NSE 500 for each of the above crashes

Dot com bust - Approx. 560 days out of market saving 50% of your money

NSE 500 during the dot com bust: out of market from 17 Apr 2000 to 3 Dec 2001, a 45.6% fall over 595 days

GFC - Approx 420 days out saving more than 50% of your money

NSE 500 during the GFC: out of market from 25 Feb 2008 to 20 Apr 2009, a 56.7% fall over 420 days

Covid Crisis

As the fall was very sharp, it would have only protected 13% of money for approx 125 days out of market

NSE 500 during the Covid crash: out of market from 2 Mar to 6 Jul 2020, protecting a 13.3% fall over 126 days

Russia - Ukraine war

Approx - 125 days, saving 10% of the money

NSE 500 during the Russia Ukraine war: out of market from 21 Feb to 1 Aug 2022, an 11.8% fall over 161 days

if you want to add this indicator in your armour below is Trading view pine script code

//@version=5

indicator(“10 EMA vs 20 EMA Background”, overlay=true)

// Calculate the EMAs

ema10 = ta.ema(close, 10)

ema20 = ta.ema(close, 20)

// Change background color based on EMA conditions

bgcolor(ema10 > ema20 ? color.new(color.green, 90) : color.new(color.red, 90), title=“Trade Window”)

// Plot the EMAs on the chart

plot(ema10, color=color.blue, title=“10 EMA”)

plot(ema20, color=color.orange, title=“20 EMA”)
